recommend me a ps printer i m in the market for a laser printer used printers are fine non apple printers are fine but whatever printer i get must fit the following required features postscript dpi emough memory to download fonts the cheaper the better i d prefer under nice things anything over pages per minute scsi output for a font disk smallish footprint don t care about postscript level ii networking its just for me and always will be color i know about freedom of press but i ve also heard that its painfully slow i can tolerate about ppm but anything slower than that and i m not going to consider the price savings worth it i d be curious to hear people s experience with it tho i also infinitely prefer laser over ink i used to use hp deskjets in my last job and wasn t impressed with the quality i m a laser bigot and the first to admit it i ll be using the printer to layout pages of a book i m writing the page will include multiple fonts ps graphics scanned line art and maybe greyscale pictures not sure yet the quality doesn t need to be spectacular but it needs to be clear and readable printers i ve been looking at used laserwriters the plus the nt the ntr its my understanding that only the ntr has a scsi out for a disk true personal laserwriter ls and ntr i have access to the apple employee discount i work for one of apple s spinoffs so i can get these reasonably cheaply i ve heard bad things about the ls comments i m leaning towards the personal ntr cause it has a nice small footprint laserwriter select i hear it doesn t have postscript but i haven t seen anything for sure i heard mumbles once about a postscript upgrade used hp laserjets i ve worked with the ii and iip on another platform and they were painfully slow are they that bad on the mac i ve seen ads for an epson ps laserprinter that is running quite cheap any comments on this printer i hate the styling too many ouput trays but if its a decent printer i ll consider it thanks for any comments laura lemay lemay netcom com writer of trifles in shadows and blood

re stereo sound problem on mac games in article qsfak skc network ucsd edu doug p book dpb sdchemw ucsd edu writes hi i think i have a problem with the stereo sound output on my quadra but i am not totally sure because my roomate has the same problem on his powerbook any info or experience anyopne has would be greatly appreciated when i hook my quadra up to my home stereo system the following types of sounds mono as far as i can tell all play fine through both speakers system beeps already provided ones such as indigo and ones i record armor alley spectre spaceward ho but the following games only play out of the left channel lemmings out of this world awesome game btw glider oids but still stereo system beeps do play in stereo through both speakers the one i m specifically referrring to is apocolyptic beginning which my roommate downloaded from some ftp site sumex all of the symptoms are the same on my rommates he can t run ootw because he doesn t have color we re both running system does anyone with lemmings or the other three games i mentioned above get sound out of both speakers on a mac ii class quadra lc powerbook or greater centris se etc stereo machine i used to have a mac ii and i sort of rememeber lemmings playing in stereo on that machine not just on the left channel i could be mistaken though if there were a problem with the quad s and pb s i am wondering why the system beeps still play in stereo if there isn t a problem with our machines i wonder why the games above are apparantly written to support only one channel of stereo when they could just use mono sounds so the mono sound would at least come out of both speakers like spectre etc do quadra s and powerbook s have the same roms to my knowledge so maybe this is a rom problem if so though why wouldn t system patch over this problem thanks for any help you can provide in article apr kth se jon wtte d jwa hemul nada kth se writes mac sound hardware is diverse some macs play in stereo and mix the output the se for instance while others play in stereo but only has the left channel for the speaker while some are truly mono like the lc developers know that stuff played in the left channel is guaranteed to be heard while the right channel isn t some send data to both some only send data to the left channel the first is preferrable of course okay i guess its time for a quick explanation of mac sound the original documentation for the sound hardware im documents how to make sound by directly accessing hardware basically you jam values into all the even bytes from soundbase to soundbase x this was because of how the mac and some later machines generated sound was by scanning this block and d aing every even byte the odd bytes went to the floppy on some machines when the mac ii and apple sound chip was invented it was designed to generate stereo sound it was also designed to be compatible with we had once documented so storing bytes at the even values at soundbase meant i want to play a mono sound and so it was emulated but apple had since retracted the documentation on soundbase and decided not to document the lowest layers of sound generation so apple never explained where to stuff bytes if you want to make stereo sound enter game developers the sound driver and current sound manager are inconveniently lame for making games furthermore people who port from the ibm don t want to learn more apis so it has become popular for game writers to write to soundbase to make sound since it is very easy since the mac ii apple has had many different kind of sound output hardware and the only things they have in common are that writing to soundbase works on some hardware mac ii iix iicx iici at least writing to soundbase gets you mono sound through both speakers on some macs quadra at least writing to soundbase gets you mono sound on the left channel only both are technically correct interpretations of the original specification but one is obviously preferable for asthetic reasons if developers use the sound manager and i think the sound driver mono sounds will typically come out through both channels regardless of the underlying hardware it is possible to specify you want to generate left channel only but no one does if developers write to sound base their games will only come out the left on some games the other problem the original mac ii only producing left channel sound on the internal speaker while the se mixes both isn t really related it is due to the post generation amplification used on the motherboards of the different machines it only affects true stereo sounds sounds which are actually mono will play on the internal speaker no matter what machine you have now to more directly address the question the games you list lemmings out of this world awesome game btw glider oids and also hellcats super tetris oxyd and many more these are just what i ve tested cheat and write to soundbase and so are only left channel on quadras other games you list armor alley spectre spaceward ho and also pga tour golf civilization and more these are again only from personal experience use the sound manager and work fine on all machines the more of the story is to developers don t cheat really i am absolutely positively not allowed to do what i am about to do but i m going say it anyway stop cheating on sound really soon you will be sorry as even those without external speakers will be disappointed with your sound on future hardware the grace period is about to end the sound manager is understandable now and works pretty well and will work even better soon so use it in conclusion to doug it isn t a hardware problem at least not a bug to jon it isn t a choice to developers as to whether they want to send sound to both channels if they do it the right way it is taken care of automatically if you cheat there is not way to make it work on all hardware have fun disclaimer number i don t work on sound here at apple i m just pretty well informed so don t write me with sound questions disclaimer number if it says up above that i wrote anything like the grace period is about to end then it is a bug in your news feed since i am catagorically not allowed to say anything like that you know what i mean disclaimer number i don t speak for apple just me steve bollinger

driver i have an old jasmine drive which i cannot use with my new system my understanding is that i have to upsate the driver with a more modern one in order to gain compatability with system does anyone know of an inexpensive program to do this i have seen formatters for buit have no idea if they will work i have another ancient device this one a tape drive for which the back utility freezes the system if i try to use it the drive is a jasmine direct tape bought used for w tapes techmar mechanism essentially i have the same question as above anyone know of an inexpensive beckup utility i can use with system all help and advice appriciated

calling all mac gurus question for those familiar with quadra vram i put k vram simms in my quadra in the slots closest to the ram simm slots and i got no results whatsoever i have been told that the built in video should support at least bit and maybe bit color on a macintosh color display however the monitors control panel still lists bit colors as the highest possible does it make any difference which slots you put the simms in do you have to do something to activate them do you have to do something to the monitors control panel btw i am running system with megs of ram charles p cox jr computer engineering case western reserve university cpc po cwru edu cox snowhite eeap cwru edu

re non apple mini docks available in article c pc f n i rahul net jonathan mecca epri com writes a a deguzman deguzman after math uiuc edu wrote my boss is considering the purchase of a powerbook or duo he is leaning towards a because of the math coprocessor for mathematica but would get a duo if he could find a mini dock with a coprocessor have any third parties announced such a beast i believe that e machines might produce something of this nature yes e machines makes two mini docks the powerlink presente and the powerlink desknet the presenter offers a variety of video out options including ntsc rgb and svga it also has sound out floppy drive port and a power port unfortunately no scsi port and it blocks the serial port the desknet has the standard ports plus built in ethernet alas none of these have an fpu in the future rasterops is putting out a mini dock but the name escapes me now it is supposed to support bit color and quadra comparable video speed no idea if it has an fpu hope this helps beth corbo

re syquest in article hydra gatech edu gt a prism gatech edu anthony s kim writes i remember someone mention about a meg syquest has anyone else heard anything about this i d be interested in the cost per megabyte and the approximate cost of the drive itself and how they compare to the bernoulli i think you must be talking about the syquest code named mesa i believe it is a winchester technology drive pretty much like the other syquest drives in terms of how it works according to the latest macleak the drive has a ms access time mb s sustained throughput these figures are from memory so they could be slightly off but they give you an idea of performance nonetheless the drive was originally released for the pc and just recently was released for the mac world don t ask me what the differences are and through they are currently in limited supply according to a syquest rep they are in the process of ramping up for mass production i have already seen them advertised by a number of manufacturers in macleak including pli massmicro clubmac and macwarehouse s poweruser the pli and massmicro units are priced at just around the lesser name brands are going for around for an external drive cartridges which hold mb sell for about each at these prices the drives and cartridges are cheaper and better performing than the mb drives cost per megabyte compares favorably with other cartridge drives and bernoulli drives but for large amounts of data optical is still cheaper and more reliable personally i m excited by the new drive and look forward to getting my hands on one chris wand egotism is the anesthetic that dulls the pain of stupidity frank leahy

mac ibm info version send follow ups to comp sys mac advocacy sorry about the header but the pnews here does not let one easily change the headers and i gave up after a year of trying this sheet is also available by ftp on sumex aim stanford edu in the info mac report as mac ibm compare txt mac ibm info version the reason for this general data sheet is to consolidate and condense the information out there so that people in both camps can be clear and accurate about what they are saying about their machines since computer technology is always changing there are always going to be points in which the sheet will be lacking or incorrect on information so please just don t say the sheet is incomplete or incorrect but also give me clear and concise information to make the needed corrections all prices are in us dollars to keep this data sheet organized please provide if possible article citations for the information provided or corrected and keep the opinions to a minimum as this is a general data sheet keep the info provided simple so i can understand what is being talked about and can explain it to others finally keep the information relevant to the section corrected for example os code in rom is software contained in hardware so no more of the but it is supported in os disk software data for the hardware section please thank you note for proper reading off line this document

drivers video and operating systems in the ibm world intel microsoft and other hardware and software developers are working out plug and play standards pc week color support display mac mhz pixel clock standard all present macs support the use of bit color through bit color quickdraw in rom bit color quickdraw allows an almost transparent capability to display and edit x bit images in y bit color and retain all the colors of y bit color where x and y independently are or regardless of monitor resolution dpi color to dpi palettebook or monitor type including autosynchronous vga mcga and svga monitors with ranges including hz vertically and khz horizontally and only a hardware video adaptor macuser aug older machines that supported color se ii iix and iicx had only bit color in rom and needed a software patch to use bit color macuser special to keep costs down and speed up most macs have only or bit display capability built in but most of those can be expanded to display bit color presently quickdraw is optimized for dpi display quickdraw qx will change this in addition quickdraw allows in macs with a nubus slot more then one monitor to be used in any combination from two monitors showing the same thing to multiple monitors acting as one large large monitor with any degree of overlap of the pictures vram video ram standard for present non powerbook mac s handling of built in video from a bit color palette vram provided runs a bit color x display expandable to bit color or a bit x display sound output standard in all macs since the k stereo sound became standard with the se ibm even though pcs have rom bios definitions of how the operating system interacts with the video hardware nan zou the use of drivers bypassing bios video hareware inconsitancies see super vga below and nonstanderzation of clone bios have left resolution of video display hardware os and program interaction up to the os and video hardware in question faisal nameer jawdat in addition ibm and clone makers never bothered to provide a standard hardware mechanism for software to determine what display mode is actually present matt healy nor a standardized screen drawing toolbox like mac s qd as a result the os must be very well written to detect some modes especially with some third party cards or to use them consitantly at present things are so dependent on the interaction of the program os print driver and monitor card that editing bit pictures regardless of color mode os and monitor type card combination as one can do on the mac is impossible with an ibm for example one cannot edit a bit color picture done on a os with a svga monitor on a with vga bit color palette and dos and still have all the colors one started out with later ibm machines will have integrated graphics accelerators faster processors and modular upgradeability and may have built in sound cards cd rom and ethernet pc week mda monocrome display adapter original character mapped video mode no graphics x text cga color graphics array x colors or x b w color palette bad for the eyes ega enhanced graphics array x colors from color palette and some lower res some versions could run at colors bearable on the eyes vga video graphics array x at colors x at colors and some others these two are the most commonly used all modes have a k clut from a to bit ibm or a bit mac color palette mhz pixel clock mel martinez monitors use analog input incompatible with ttl signals from ega cga etc mcga multi color graphics array subset of vga that provides all the features of mda cga but lacks some ega and vga modes like vga x x dictionary of computer terms dct common on the initial ps implementation from ibm and some ps models svga super vga this is not a standard in the way the others were but instead was a catch all category for a group of video cards as such with each manufacturer using their own implementation scheme svga was chaos with people debating as to what is svga and what is not in an effort to make svga more of a standard vesa was established and is used in the newer units but things are still a mess video is either k or m today resolution of x and x at and colors are common newer ones since have the sierra hicolor ramdac giving bit colors at x some of the very newer ones can do bits per pixel usually at x speedwise too much variation some very slow western digital paradise based for example some very fast s c based for example some are so so like tseng et a very popular chipset some limiting factors overcome by mhz vl bus s linear address mapping were mhz isa bus at architecture where the cpu looks at the card through a k window etc other non svga standards a ibm s own standard interlacing graphics accelerator with graphics functions like linedraw polygon fill etc in hardware some clone implementations from ati are the fastest video available today though some clone models do not have interlacing tms high end graphics co processors usually some do bit speeds up vector oriented graphics like cad xga extended graphics array newer and faster than a only available for mca bus based ps s clones are coming out soon emulates vga ega and cga dct max resolution at x x b same as a also some bpp modes xga accelerates graphics functions up to times faster than standard vga in windows and os including line draws bit and pixel block transfers area fills masking and x y addressing has an intelligent way to detect and co exist with other xga cards so multiple desktops like on the mac may not be far away since this is an architecture its resolution and color depth isn t fixed ibm implements only bit color while other companies can have bit color through ibm technical licenses refresh rates up to hz ensures flicker free rock solid images to reduce visual discomfort and is vga compatible up to x on os some monitor types usable by mac see mac section above for specific details expansion both mac ibm scsi only external device expansion interface common to both mac and ibm allows the use of any device hard drive printer scanner nubus card expansion mac plus only some monitors and cd rom main problem there are a lot of external devices which are internal terminated which causes problems for more then two devises off the scsi port a scsi chain is supposed to be terminated only at the begining and at the end any other set up causes problems for either mac or ibm scsi devices per scsi controller bit asynchronous mb s ave and synchronous mb s max transfers difference is due to scsi software drivers fast scsi is a misname for bit scsi in scsi mode see scsi for details scsi devices per scsi controller in scsi mode scsi is fully scsi compliant and bit scsi tends to be implemented as a very fast scsi since it does not require the different controller interfaces in hardware and software that and bit scsi do transfer speeds are mb s with mb s burst bit mb s with mb s burst bit and mb s with mb s burst bit wide and fast since bit scsi can use scsi software drivers and hardware at bit scsi speeds and as such is limited to devices sometimes it is mistakenly called fast scsi bit fast scsi requires a scsi software driver and scsi electronics but can still use the scsi ports wide bit and bit scsi require a different scsi port electronics and software driver from scsi which makes them more expensive than other scsi interfaces mac scsi asynchronous scsi built in standard since the plus even though apple developed some specifications for scsi controlers the os scsi manager needs to be rewritten to take full advantage of the features of both scsi interfaces as a result present scsi macs use bit scsi as a fast asynchronous scsi presently quadras are the only macs with a scsi controller chip built in digital review oct v n p though they lack some other parts of the hardware like the wide scsi port interface since other macs require a nubus card to use scsi older nubus macs had a bottleneck due to the speed of the nubus and cpu rumor some cyclone macs june will come with a wide fast scsi port standard and have a rewritten os scsi manager ibm scsi scsi is not too wide spread yet generally not bundled with systems except as add on eisa and vesa local bus adapters avalable like the mac bit scsi is used as a very fast scsi by most controllers out there unlike the mac ibm has no exact scsi controller specifications which results in added incompatibilities for scsi mac memory expansion with a few exceptions the mac has used non parity pin bit simm memory expansion since the plus while pin bit parity simms could be used in these macs only special iicis could make use of the parity feature by convension both simm types are called pin simms the iifx used pin parity simms the lc iii c and q all use a new pin simm that is accessable by bits at a time and is used in ibms the mac does a complete memory check at startup by writing reading every memory location if something is seriously wrong with a simm the mac will not boot and give a sound chord indicating what the problem is since macs made before feb managed memory baced on data path simms had to be installed in pairs bit or in sets of bit the centris and quadra eliminate this with a new memory management setup that allows memory to be upgraded one simm at a time if the simms are the same size are used then the memory is interleaved across the two simms resulting in a performance boost on ram access macworld apr printers adbs and modems built in interfaces standard monitor interface and

burst mode mb s byte in development cpu expansion handled either through the pds or the nubus unlike pds nubus cpu cards example radius rocket allow use of multiple processors at the same time this is like having two or more macs in the same box able to dual task or joinly process depending on the card or software involved each nubus card needs its own memory but most nubus cards of this type come with mb ram simms on the card standard ibm memory expansion parity simms non parity simms some newer models do a mac like simm memory check or a dozen or so different types of memory boards hd

of os and hardware commands have been put into rom this allows apple to control its machine by putting key hooks for the mac os quickdraw menu commands print mouse scsi sound drivers etc in rom which require clone makers to use the rom chip or read rom on to disks which requires access to the proper mac since different macs have slightly different rom chips plus vs classic for example with key hooks for the os support interface in rom programers do not have to worry as much whether the disk os has the necessary hardware commands or that those commands are consitant and therefore can write smaller programs this also allows apple greater control over hardware software standards and that the disk os can be smaller and with some of the tookbox command code in rom with lower ram

may keep some old system fonts from the previous system inside the system file this can eat up any ram benefits and cause other problems apple itself recommends removing all fonts from the system file a ux unix needs mb ram mb suggested mb hard drive and a or equivalent to run this bit preemptive multitasking os is large due to being unix and needing translators between it and the mac roms price note sound output was supported in oses to by many formats including the following snd wave asnd fssd qssn smsd soun dc d and dcfl in the sound manager was optimized for the sound standards snd and aiff which causes some playback problems for the old formats though most still play ibm machiness have little gui code data and hooks present in hardware for programmers to work with so most of the coding must be provided in the os since hard disks were slow the disk os code is read into ram in addition what little rom code there is also read into ram a process called shadow rom this results in faster implementation since ram is faster then proms or eproms having most of the os code on disk has the advantage of being able to better optimize the code given a certain piece or collection of hardware which is harder with a rom based system due to the patches needed in addition it reduces the need for and size of patches if a major revision of the hardware support is needed side note the ftc charged that microsoft formed a os trust by not providing all feature documentation for its oses to developers outside ms and designing its windows and dos apps to fail under os undocumented windows and there is deliberate code in windows nt beta which causes the install to abort if os boot manager is present gregory hicks info ibmpc digest v due to a conflict of intrest by one member the vote of the ftc judicial council for action against microsoft was a tie which resulted in no action rumors the ftc will presue the matter likely to the point of choosing a new member or whole new council in addition the government has turned down microsoft s copyright of windows which would allow it to charge a fee for developers using their hooks pc week microsoft oses dos has a k barrier

cause program aborts and would abort to the dos prompt at the point where they occured most present compilers handle this better result there is little consistent handling of numbers between dos windows and os programs nor between programs for just one os networking includes printing wysiwyg printing can be a problem with either mac of ibm machines especially if one sends truetype fonts to a older style postscript printer mac hardware built in localtalk network port and a built in printer port localtalk has moderate speeds kb s requires special connectors for each machine and up and can be run off of either the printer port to include very old macs or the network port standard today built in ethernet is becoming common but many older macs require a pds or nubus card at about for each machine these cards provide three connectors and transceivers thick thin and baset for ethernet the macintosh quadra family and some centris models includes ethernet interface on motherboard with transceivers available tokenring has been a network option since software appletalk the suite of protocols standard with mac os which can use variety of media types appleshare client software included with the os as well and can connect to file servers such as novell netware com open banyan vines dec pathworks apple s appleshare servers system file sharing machines and afp servers running on variety of unix hosts mactcp allows typical tcp ip communications telnet ftp nfs rlogin a later version will have unix x open transport interface xti built in by the end of macweek third party software to connect to nfs servers dec pathworks provides decnet support peer to peer file sharing software built in to system see os section full server software is extra printing requires connection of the printer and the printer being selected in the chooser changing printers is by selecting a different name in the chooser the same is true of connecting to servers printing bugs monaco truetype font is different then the screen bitmap font quickdraw qx is suppossed to fix this and similar problems ibm hardware localtalk not widely used ethernet and tokenring software novell netware banyan vines decnet windows work groups appletalk protocols and appleshare subset of appletalk each of the ms dos networking schemes are in general totally incompatible with the others once you have chosen one you are pretty much locked in to that product line from then on windows work groups is a little more forgiving and removes some of this problem novell netware is the biggest percent of the corporate market and in general is more powerful and offers better control management security than appleshare but it s also more complex to set up and manage this will change due to the use of the mac finder and file management system by novell pc week infoworld dec macweek printing very os dependent dos if it s a single user then you plug the printer into the parallel port and don t worry about it tweeking may be needed with poorly written software network printing is not controlled by the system but is mostly implemented by the actual program therefore performance varies from one software program to the next windows x supports standard drivers and can do a good job of showing jobs in the print queue but it always lists printers as active even if they are not this becomes a problem if there are several incompatible printers on the same net because there s no way for software to reliably determine which printer is active right now windows for workgroups is more mac like and intelligent about this os mac like the os deals with printers with apps making calls to the os printing bugs due to poor programing some programs for all the above oses do not have wysiwyg printing this is the fault of the programs in question and not that of the os involved price issue this is very dynamic with mac providing more build in features than ibm and ibm being more get only what you need then mac and price wars by both worlds the ibm machines modualar nature prevents any kind of true hardware standarization which in turn requires oses and programs to be very complex to handle all the variation in hardware when one adds all the standard mac hardware features to an ibm built in input output sound support scsi pds built in monitor support built in networking standard mouse interface and nubus in higher machines the mac tends to be cheaper then an equivalent equipted ibm machine especially since some ibm monitors can be used with macs which cuts some more of the

re quadra scsi problems attention mac quadra owners many storage industry experts have concluded that mac quadras suffer from timing irregularities deviating from the standard scsi specification this results in silent corruption of data when used with some devices including ultra modern devices although i will not name the devices since it is not their fault an example would be a sony inch mo without the special mac compatible firmware installed one solution sometimes is to disable blind writes to the best of my knowledge there aren t any problems with quadras and blind transfers trouble with blind transfers usually means the programmer screwed up the tibs or didn t test their driver with the device in question well designed tibs poll or loop at every point where delays of sec occur this usually occurs at the first byte of each block of a transfer but some devices can hiccup in the middle of blocks if this happens in the middle of a blind transfer there is the possibility of losing or gaining a byte depending on which direction the tranfer was going in anycase the scsi manager will eventually return a phase error at the end of the transaction because it is out of sync actual data loss would only occur if the driver didn t pay attention to the errors coming back note that this effect is not caused by anything actually on the scsi bus but rather by the transfer loops inside the scsi manager the problem occurs when the processor bus errors trying to access the scsi chip when the next byte hasn t been clocked yet also note that the bus error is dealt with by a bus error handler and doesn t crash the machine clinton bauder apple computer

re iisi question the si has a single expansion slot that can be either pds or nubus but not both together the card lies parallel to and above the motherboard hd and requires an adaptor slot to do this there are nubus and pds adaptort cards thus what kind of slots you have depends on what kind of adapter card you have with the exception of the radius rocket all nubus cards i know of work in the si pds slots and thus cards are mac specific thus not all pds cards work in all macs from planet bmug the firstclass bbs of bmug the message contained in this posting does not in any way reflect bmug s official views

re cache card for iisi can some people with cache cards please post speedometer numbers they get with the cards i have only one report which seems to indicate that a k cache card gives you only about a speedup ok i have a record that shows a iisi with and without a kb cache it s small enough that i will attach it i have also measured some real programs with and without the kb cache the speedup varies a lot from app to app ranging from to i think an average of is about right the subjective difference is not great but is sometimes noticable a simple cache card certainly does not transform a iisi into something enormously better i do not have an fpu the conventional wisdom says that cache cards from all of the makers offer about the same speedup and that there is not much difference between k and k caches i bought mine from third wave for well under i have had absolutely no problems at all with it if you get complete speedometer runs for a k cache i d like to see them let s check the conventional wisdom the so called performance rating numbers by themselves are of no interest cheers peter newton newton cs utexas edu

re stereo sound problem on mac games steve bollinger buzz apple com writes enter game developers the sound driver and current sound manager are inconveniently lame for making games the sound driver is pretty ok since it s fast sound manager used by the book is useless disposing of sound channels as soon as sound has completed is out of the question for games with smooth animation it s too slow the sound driver is so much snappier than sound manager unfortunately system supports it poorly making programs crash occasionally the more of the story is to developers don t cheat really i am absolutely positively not allowed to do what i am about to do but i m going say it anyway stop cheating on sound really soon you will be sorry as even those without external speakers will be disappointed with your sound on future hardware the grace period is about to end the sound manager is understandable now and works pretty well and will work even better soon so use it well i want my code to work on old systems too i don t know about sys but at least on there are bugs in the sound manager that causes channels to hang with no error message this happends when i keep a channel open for long periods necessary for performance and play many sounds stopping sounds halfway callbacks seems not to be reliable then only way i can safely tell if a sound has stopped playing is to inspect private variables in the channel qhead i think it was and the only way i have found to tell if a channel is hung is to inspect an undocumented flag and modify it am i happy with this nope i consider writing to soundbase simply to get rid of the bugs any better suggestions silent games is not among the acceptab e solutions ingemar ragnemalm dept of electrical engineering uunet mcvax enea rainier ingemar university of linkoping sweden ingemar isy liu se
