re what is rom accelerated video in article apr reed edu especkma reed edu erik a speckman writes in the macuser article on the new centris and quadra machines mentioned that the c and the q and not the c had rom accelerated video what is it i don t recall seeing it in dale adams post of course it was in dale s post just not in the words that macuser used rom accelerated video just means that some quickdraw commands has been rewritten inside the rom to take advantage of the addressing modes commands that do fills should be slightly faster since the new instructions fetch bytes at a time versus one

re printer blp elite in article ghoetker nova glen hoetker ghoetker nova sti nasa gov writes i m in the market for a post script compatible laser writer my needs are pretty modest so dpi pages a minute would be just fine my budget is also pretty modest so inexpensive would also be good it will be working from a single mac but networkability would probably be a good investment for the future with that in mind anyone have comments about the suitability quality value of a gcc blp elite printer i just recently purchased the gcc blp elite and i really like it my needs are much the same as what you describe in addition i wanted to get one that i could access via appletalk so that eliminated the new line of inexpensive printers from apple the print quality is good to excellent based on what font you re using and what paper you use i m still experimenting with different papers but a medium grade laser printer paper seems to work fine printing envelopes transpariencies letter head or other single feed jobs is very easy there is an adjustable automatic centering guide on top of the sheet feeder which aligns the paper properly and doesn t feed a sheet from the sheet feeder as some do i have no affiliation with gcc just a satisfied customer earl d fife department of mathematics fife calvin edu calvin college grand rapids mi

re daystar again in article c fqno hh news udel edu bill johnston johnston me udel edu writes i m going to buy a daystar with mhz for the se since there were so many mails about problems with this board my questions does the board work with and a ux does anybody know problems with any kind of software well i haven t seen any reports of problems with the turbo but to my knowledge daystar has not released a version of the board that works with anything but the iisi and iici and they have not finished tweaking testing for use with a ux this may not happen until the a ux upgrade is released my guess so i d recommend waiting or buying the mhz board and upgrade later when a ux compatibility is assured turbo interface cards for the ii iix se iicx etc will probably be available sooner but if a ux compatibility is a requirement it is probably best to be patient and let someone else be the pioneer an added advantate of waiting for the daystar for the se is that just as with the power cache the accelerator will plug into the cpu socket leaving the pds slot free for a video card or ethernet card with daystar s upgrade path it s a no lose situation earl d fife department of mathematics fife calvin edu calvin college grand rapids mi

re ad conversion b clark nwu edu brian clark writes in article apr vax oxford ac uk roes vax oxford ac uk wrote i am working a data acquisition and analysis program to collect data from insect sensory organs stuff deleted another alternative is the use of the sound input port can you really make due with the non existent dynamic range of an bit converter of probably dubious linearity and monotonicity and perhaps ac coupled as well it clearly depends on the type of questions you are asking but in many cases it will do fine the critical information from the neuron is in the firing frequency maximum about action potentials per seconds and not in the amplitude of the signal or in details of the signal shape so the resolution of about you get with an bit convertor is more then sufficient ac coupling does not have to be a problem either since in many cases you are not interested in the dc level my pre amplifier is ac coupled also the critical point is the lowest frequency that will pass if the cutoff point is to high the action potentials will be slightly distorted but even that normally does not matter since it is the occurrence of the spike that is important however i do want to know what exactly i can expect before i start battling with the toolbox to get it going as yet i have no clue were to start looking for the technical specifications peter roes vax oxford ac uk

re to fix trackball in article br a auvm american edu br a auvm american edu writes the trackbal on my pb no longer moves in the horizontal direction when i called the nearest authorized apple service person i was told that it probably needed replacing and that would cost me over ouch can anyone recommend a less expensive way to fix this problem one strange symptom of the problem is that when i take the ball out of the socket and shine a light into the hole i can make the cursor move horizontally by moving the wheel with my finger it works fine that way but won t work if i turn off the light any suggestions or comments ben roy just a poor college student internet br a american edu ben since you re obviously adept enough to understand how the trackball works the only thing short of repairing it that i can think of is a thorough cleaning of all the parts and then checking for the proper placement of the little blue rollers since they aren t fixed in position on their stainless steel pins you might try sliding them into a slightly different position on my powerbook i can slide them almost completely out of contact with the trackball in fact one of the notes from sumex on fixing the trackball advocates sliding the roller so that its edge contacts the ball not the center cylindrical area i ve done this with my pb and it does seem to improve the feel but needs to be adjusted from time to time i just popped open one of our office s pb s and while there isn t as much latitude for movement one could still adjust the roller slightly if your pb is the same it might help i would suspect the most likely culprit to be a slippery blue roller if you can take it out clean it with a mild soapy solution or isopropyl alcohol also be sure the ball is grease free if you drop the ball in minus the retaining ring roll the ball and see if it is actually causing the axle to spin if all this still doesn t solve it then maybe a new one is in order it could be an electrical connection in which case replacement would be necessary but my experience with both mice and trackballs has been that dirt has been the normal problem not an electrical malfunction hope this helps murray murray m altheim ils ont l orteil de bouc d un chevreil l oreille instructional consultant la corne d un chamois la face vermeille csu sacramento comme un rouge croissant dancent toute nuict altheimm csus edu dedans un carrefour ou pres d une eau qui bruict

re lcd overhead projectors in apr ug eds com jan camhpp mdcbbs com jan vandenbrande writes i am looking for one of those color lcd screens you place on an overhead projector and control the presentation with a mac can you recommend me a particular brand what price are we talking about for a good display you must get an active matrix panel and a very bright overhead projector designed to be used with an lcd panel i e stage must not get too hot i tried out a proxima ovation unit and liked it but i needed a brighter projector i used it with a m it is also too expensive for what you get imho prices of active matrix panels are rumoured to drop substantially sometime this year something to do with tarrifs being lifted i think in canadian dollars the proxima ovation models ranged in price from about to and a good overhead projector about to for that kind of money you can get a brighter image from a three beam projector but sacrifice portability oh yes proper room lighting is extremely important especially if you want your audience to have enough light to read handouts and not have that light wash out your display at the front of the room tricky to get right

converting keyboard for mac plus i have an old mac plus a couple of years ago i bought a shiney new lc it came with apple s new keyboard with abd ports i replaced it with a mac pro plus extended keyboard which i thoroughly enjoy thank you very much well i have this extra keyboard which i would like to use on the plus but there s a little problem the plus uses an rj jack for keyboard input and the new keyboards don t i got an extra adb cable from my local apple dealer they re such nice people but they couldn t tell me the order of the wires there are four wires in the adb cables black white red tan i know one s a ground one gets the serial signal one supplies volts and i forgot what the fourth one does anyway if you hook them up wrong you ll fry a board and i really don t want to do that if any brave souls out there have done this before please e mail your experience directly to me i would greatly appreciate it especially since apple s original keyboard is not ergonomically correct btw i did take apart my new keyboard to see if i could find the correlation between the wires for the rj jack and the adb since it has both but no such luck the connections are soldered inside of little boxes oh well tis the blink of an eye tis the draught of a breath from the blossoms of health to the paleness of death from the gilded saloon to the briar in the shroud o why should the spirit of mortal be proud william knox shagberg vm cmp ilstu edu

mac portable ram problems coprocessor not installed i just recently bought a mb ram card for my original mac portable backlit and have since had some bizarre crashes it happens when i put the machine to sleep and wake the machine up sometimes it will just freeze the cursor and lock the machine up forcing me to push the reset switch other times it will give me the usual bomb box with the error message of co processor not installed i know one solution is not to put the machine to sleep but does anyone have any ideas on what could be causing this or better yet what might fix it the memory card is psuedostatic ram and goes into the pds slot that probably figures into the problem the manufacturer is king memory not kingston from irvine ca they say the problem is in my machine any ideas gene wright gene jackatak raider net gene wright jackatak raider net

re interesting adb behaviour on c in apr waikato ac nz ldo waikato ac nz lawrence d oliveiro waikato university writes i have heard of no such warnings from anybody at apple just to be sure i asked a couple of our technicians one of whom has been servicing macs for years there is no danger of damaging logic boards by plugging and unplugging adb devices with the power on the problem is that the pins in the adb connector are close to each other and if you happen to bend the cable a little while inserting it you short the adb port if you take it to an apple repair centre that means a new motherboard though a component replace is physically possible same goes for serial ports localtalk as well cheers h jon w tte h nada kth se mac hacker deluxe this article printed on recycled electrons

adding int hard disk drive to iicx i haven t seen much info about how to add an extra internal disk to a mac we would like to try it and i wonder if someone had some good advice we have a mac iicx with the original internal quantum mb hard disk and an unusable floppy drive we also have a new spare connor mb disk which we would like to use the idea is to replace the broken floppy drive with the new hard disk but there seems to be some problems the internal scsi cable and power cable inside the cx has only connectors for one single hard disk drive if i made a ribbon cable and a power cable with three connectors each for motherboard for each of the disks would it work is the iicx able to supply the extra power to the extra disk what about terminators i suppose that i should remove the resistor packs from the disk that is closest to the motherboard but leave them installed in the other disk the scsi id jumpers should also be changed so that the new disk gets id the old one should have id it is no problem for us to remove the floppy drive as we have an external floppy that we can use if it won t boot of the hard disk thank you torbj rn rognes email rogntorb idt unit no

disappearing hard drive in lc the internal hd in my lc disappeared for a day last week and i d like to hear any reasonable theories folks can suggest for what happened it is an lc with mb of ram and an mb internal drive running system with a few scsi devices in a so far as i know properly terminated chain i had shut down the system for a day i was out of town and we sometimes have thunderstorms this time of year and upon restarting got a blinking question mark i booted from a floppy and saw that my external hd seemed okay but there was no sign of the internal i installed a system folder on the external and was indeed able to boot from it i tried things like disk first aid and silverlining to inquire about the internal drive they either could not find it or got errors in trying to talk to it silverlining claimed it was a connor drive but it is a quantum well i d backed things up so i was able to work but at some point i noticed that the internal had reappeared now disk first aid says that all s well etc things seem to be fine but what happened was this a warning that something the internal hd or something else is about to die i m definitely nervous and if this is a signal that the internal hd is sick is it true that i can only put up to a mb drive inside an lc some folks have claimed there s a limitation in the lc other n size or power while others and that includes lacie over the phone say anything that fits is okay thanks for answers

re lc ram upgrade will be slow douce tfsquad mn org andrew geweke writes i cannot speak for dale but i am quite sure that the macintosh uses the full bit or bit data path to its full advantage that is it is running as fast with two or four pin simms as it would with one pin simm now it may be that longword accesses assuming a bit data path here get the first byte from the first simm the second byte from the second and so on this would mean that each longword of memory is actually split among four simms one for each byte on the other hand it could be that the simms are interleaved by word or longword not just by byte or they could be successive in memory and the memory controller deals with the eight bit data path that each one has i suspect though that they are interleaved to some extent so that bits can be read or written at once this would indicate a byte level interleave i am not confusing this with the new machines longword interleave with two pin simms of the same sort although that seems to be the same sort of idea there you get an essential bit data path ro excuse me to ram instead of just a bit one yes the cpu can t handle it but when writing to successive addresses it speeds something up so dale am i right pin simms are interleaved by bytes allowing the full data bus or as is common with usenet and me in particular am i as clueless as everyone else what conclusion can be drawn from this i m trying to figure out what kind of memory configuration for the lc iii bit datapath would be fastest any ideas thanks jason macdonald jason scott macdonald jsm cornell edu jsm crux cit cornell edu technology sufficiently advanced is indistinguishable from magic cats exist so that we arthur c clarke may caress the lion

re quadra scsi problems in article qm hvinnseq shelley u washington edu tzs stein u washington edu tim smith wrote 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 that s fine but would you name the industy experts so i can try to track this down this doesn t sound right to me don t quadras use the c if so the mac has nothing to do with the scsi timing that s all handled by the chip yup that s why i m kinda curious most scsi problems i ve encountered are due to cabling noah noah apple com macintosh hardware design sun decwrl apple noah not the opinions of apple computer inc

re what to put in centris internal bay in article c jfnp fcx world std com jbailey world std com jim bailey wrote hades coos dartmouth edu brian v hughes writes tzs stein u washington edu tim smith writes jbailey world std com jim bailey writes yes you get internal mixing of the analog cd audio outputs with the mac generated audio on the mac motherboard also you can sample the cd audio using the sound control panel by clicking on the options button next to the microphone icon how do you click on the options button i ve never seen it undimmed the latest word on this is you have to disconnect the microphone cable on the motherboard then the button is supposed to un dim the audio will simply select the cd audio when the microphone is removed i don t believe the button un dims since there s nothing to select i haven t tracked down a centris to check this on though sorry i assumed that the the various new machines with the internal cd rom bay worked the same as the quadra obviously they don t yup i made the same mistake several months ago when this issue came up before noah noah apple com macintosh hardware design sun decwrl apple noah not the opinions of apple computer inc
