wrong ram in duo a few posts back somebody mentioned that the duo might crash if it has the wrong kind non self refreshing of ram in it my duo crashes sometimes after sleep and i am wondering if there is any software which will tell me whether or not i have the right kind of ram installed i had thought that the problem was the battery connection thanks in advance archon fung

re centris video problem i m having it also from push media mit edu pushpinder singh subject re centris video problem i m having it also date sat apr gmt when the computer is set for colors and certain operations are done particularly vertical scrolling through a window horizontal white lines appear on the monitor which generally but not always spare open windows these lines accummulate as the operation is continued if a window is moved over the involved area of the screen and then moved away the line disappear from that area of the screen this problem is not observed if the monitor is configured for colors or a inch apple monitor with colors is used i suspect a bad video ram chip but cannot be certain the problem has been apparent since day but has gotten worse etc has anyone not had these problems in the given configurations that would help eliminate design flaw as the explanation

re x x how do they compare in article bd c a zeus ieee org michael ameres f n z fidonet org michael ameres writes i believe it goes or will go powerpc pentium i think this kind of comparison is pretty useless in general the processor is only good when a good computer is designed around it adn the computer is used in its designed purpose comparing processor speed is pretty dumb because all you have to do is just increase the clock speed to increase speed among other things i mean how can you say a is faster than a without giving is operational conditions can you say the same when you are running a program that uses a lot of transidental functions knowing that does not have transidental functions building in to its fpu and does can you say that is still faster anyway i hope people do not decided upon wether a computers is good or not solely on its processor or how fast a processor is based on its name because one can alway do a certain things to a processor to speed it up but if we restrict our arguements to for example pure processor architectural issues or how one processor will work well and another will not based on its design then we can get somewhere with our discussions chung yang in a resent article in one of the macmags i think a mhz accelerator was slightly slower than a mhz accel but this is using a system designed for the so it stands to reason that a system designed for an ie quadra would do better so overall i d figure or so along the same lines the new powerpc stuff is supposed to run the system at the level of a fast quadra but system or whatever will allow times the speed of a in the powerpc based systems and wait for the i think it laps the pentium pro life pro women michael ameres internet michael ameres f n z fidonet org

re computer engr vs computer science in article tecot xenon stanford edu tecot xenon stanford edu edward m tecot writes a professor of mine once said the difference between a computer engineer and a computer scientist is about meaning the engineer makes more than p s the is not just a joke scott for the most part this is a bunch of bunk i ve got a computer engineering degree yet i ve spent the last years writing software that people actually use moreover the salary distinctions are incorrect i received job offers upon graduation the two jobs that actually used my hardware experience were year lower my advice is to decide which classes and projects most interest you and pick the major that allows you to take them emt well here is my worth advice from a grad student i agree with the gentlemen who wrote the comment before me the important thing is pick what ever interest you the most and learn as much as possible about it in my five years of education in this field though brief compare to alot of people i had to think about this kind of question a lot did i make the right decision in going into electrical engineering as opposed to computer engineering or cs the more i go thru school the more i believe that this kind of question is irrelevant i have come to believe that choosing cs because one does not like hardware or choosing hardware because one does not like to program is really doing an injustice of building and computer and making it useful for something everything is interwoven and inseparable cs ce and ee are all a part of a really great discipline and do depend on each other my advice is don t limit yourself but make a decision based on which major will give you the best opportunities to learn that of course depends on the curriculum at your persective school i would choose a major that allows me to explore as much as possible beside i don t know why the school would make a student choose a major before her his sophamore year hey you may be so interested in this field that you decided to learn all about the making of computers in which case you suffer a little more and go to grad school about the money don t look at the averages if you are good you are going to earn more money than anyone else if you are a superstar programmer you will earn millions like wise if you are a hotshot computer designers chung yang

re help duo problems bcherkas netcom com brian cherkas writes chess cats ucsc edu brian vantuyl chess writes i just got a duo and i m having some difficulties if the machine is plugged in to the wall adapter put to sleep unplugged from the wall and woken up it crashes of the time there s nothing but the original system software on the machine the battery has plenty of life i think this must be a power manager problem but i don t know what to do about it also the speaker occasionally makes a high pitched hiss the noise is irregular but seems to favor sleep and restart commands i ve had my duo for a few weeks now and suffer from both of the above problems i reinstalled my system software twice in an effort to combat the problems thinking they were system software problems initially reinstalling the system seemed to help but not anymore occasionally when i try to wake up the duo i get a solid screen of horizontal lines on the screen it freezes i also get the high pitched hiss occasionally but only at startup i ve called the apple hotline sos appl three times already and finally they agreed something is astray after my duo s screen would go dim and the hard drive spun down by itselft and put itself to sleep this problem only occured twice apple sent me a box to ship my duo to be looked at in new york but the problem now is intermittent and i can t afford to be without my duo at this time anyone out there with these same problems brian cherkas bcherkas netcom com i aol brianc compuserve netcom online communication services san jose ca yes quite a number of people it seems from discussions i ve had me included i bought my machine a couple of weeks ago as well and started to experience these problems apple australia via my dealer said that this problem has a number of potential causes faulty applications faulty third party hardware modems memory etc system software pram corruption and power manager corruption and the duo hardware itself none of the above are relevant in my case except the last two maybe no applications were running the system software was re installed i have no additional hardware i have found that clearing pram appears to help for a while at least hold down command option p and r on startup unfortunately the problem returns suggesting that pram is being corrupted by something system software bug i don t have any non issue inits in my system apparently the power manager can be reset by holding the reset and interrupt buttons while powering up apple s advice but since the duo does not have an interrupt button i m not sure what they mean in this case this may also help if someone can decipher apple s advice for me beyond this apple suggest that you should follow the technical procedures to check the hardware of this duo since so many others appear to be having the same problem it would seem to me that there has been a system software bug introduced somewhere along the line and quite recently too since it only seems to be recent duo purchasers who have this problem any more comments from others in the same boat are welcome particularly apple duo engineers cheers brucet bruce tulloch sydney australia brucet extro ucc su oz au complex problems have straight forward easy to understand wrong answers

attn c and duo owners be very careful when you plug in a external monitor and a external speaker make sure that all the power cords are in the same strip if you don t you take a chance of having a very bad audio buzz this is caused be a ground loop and the only way of getting rid of this loud buzz is to make sure that you have a common ground make sure that all the power cords are going in to the same strip or off the same outlet this will assure you of a common ground tim keanini sound designer timk broder com broderbund software blast crl com

asante en sc hangs scsi devices i just hooked up my mac iisi to a relatively old year asante en sc adapter the base t connection works like a charm i installed the newest drivers from asante s ftp server the problem begins when i attach one more device to the scsi chain specifically a mb drive i power up the drive then the mac the mac tests memory etc just before the happy mac face normally shows up the power light on the en sc goes out and the boot process stops so i can use the network or the external drive but not both at once this makes the asante box pretty much unusable it doesn t look like a purely electrical scsi problem because if i turn on the drive just a second or so too late so that it doesn t get noticed during the initial scsi polling the mac boots normally and the adapter works even though the hard disk is powered on and connected the mac has never once failed to boot from its internal drive up to now and i ve had it for over a year here is what i tried changing the scsi id s of the en sc and the disk several permutations changing the order of devices i e the en sc at the head or tail of the chain overterminating with an external terminator both devices have internal ones underterminating i e removing internal resistors from the hard disk trying another en sc box trying another identical drive trying several different scsi cables has anybody seen this more importantly does anyone have a solution thanks a lot e eric behr illinois state university mathematics department behr math ilstu edu or behr ilstu bitnet please avoid

re wrong ram in duo here is the macweek article describing the duo ram situation w o permission i hope that is ok jose bad ram brings some duos down random access memory boards for apple macintosh powerbook duos macweek v n feb copyright coastal associates publishing l p by raines cohen austin texas some third party memory expansion cards for powerbook duos depart from apple specs in ways that could cause crashes data loss and other problems technology works inc a ram and network vendor based here last week issued a warning about three problems it said it had found in duo ram products from some competing vendors which it declined to identify other vendors and an apple spokeswoman confirmed that the problems exist self refresh the duos require a kind of dynamic ram called selfrefreshing which can recharge itself while the system sleeps but technology works said some vendors have sold duo cards with nonselfrefreshing dram which can cause the system to lose data or fail to wake from sleep most leading memory manufacturers include the letter v in the part number stamped on their self refreshing chips nonself refreshing chips instead have an l according to techworks the chip label however may not tell the whole story newer technology of wichita kan said it uses nonself refreshing chips but adds its own circuitry to keep them refreshed while the duo sleeps speed some ram card vendors have put nanosecond dram on duo cards rather than the nanosecond type the requires technology works said however some chips labeled as or nanosecond are certified by the manufacturer to run at a higher speed kingston technology corp of fountain valley calif said it offers duo ram cards with nanosecond chips but only for the duo which is compatible with the slower chips space technology works charged and apple officials confirmed that some third party cards are too large to fit properly forcing the corner of the duo keyboard up and preventing the system from starting up normally when in a duo dock lifetime memory products inc of huntington beach calif said it originally shipped cards with this problem but has since offered all customers free upgrades to cards that fit

se rom i just bought a select and rushed home to print some grayscale pictures for my kids when i discovered that grayscale and photograde are not available if you are using an se even if you are running with an cpu you won t see this in the printer s docs and the apple rep didn t mention it to our users group either it seems that se roms won t support those features okay i guess i should have somehow known that this was the case let the buyer beware huh apple be that as it may i have been thinking about the problem and i m puzzled why can t a defencieny in the rom be made up for in software i write software for a living on unix platforms and i don t understand the it just can t be done responses i ve gotten from those i have asked so far isn t mode or somesuch piece of soft ware just such a fix anyway i was hoping someone knowledgeable about mac internals could set me straight is it simply impossible for a mac se to print grayscale or could someone armed with enough info and a little pro gramming experience cook something up that would supplement the rom s capabilities also how does one know if one s mac can support the grayscale and photograde that the select is supposedly capable of short of buying the printer and trying it out like i did thanks for your help bill wright wgw netcom com

mo driver compatibility it s my understanding that when you format a magneto optical disc the formatting software installs a driver on the disc if you insert the disc in a different drive then this driver is loaded into the computer s memory and then controls the drive and if this driver is incompatible with the drive then the disc can not be mounted and or properly read written is that correct thanks jim frazier compuserve com

card questions i m considering buying one of these to offload the internal video in my iici and to get bit color capability on my monitor what s the deal on them do they come with varying amounts of ram if so what is the max and min how much do i need for x x bits what bit depths are supported one and are all these cards accelerated or just some is it true that modern accelerated video cards are at least in general faster what bit depths are accelerated all or just bit i ve heard that some applications actually run slower with this card if they write directly to the screen or something like that is this a frequent problem how much slower is it didn t i read when system first came out that the card was incompatible if so how was this corrected finder patch some init or other has it been kept compatible with are there many other apps that it is incompatible with games or important i e non microsloth apps for example if you have a strong opinion on it s value for someone in my position let me know what you think a reasonable price is to pay for it thanks a lot for you input rick rick roy usenet rick howtek mv com america online qed disclaimer my employer s views are orthogonal to these the early bird got worms

re quadras vram question daniel salber salber imag fr writes i have a question regarding quadras vram i have tried to find info on this but i could not get precise answers on one hand we have a quadra with a monitor which is capable of bit color how much vram does it have to display millions of colors on a monitor you need mb of vram in the q on the other hand we have a quadra with a monitor which is capable of bit color only so it must have ko of vram correct this is the amount of on board vram that the q comes with i would like to take vram simms for the and put them in the so that both machines have bit color capability is it possible and if yes how many vram simms should i take from the yes this is possible technically you only need to take out of the vram simms but leaving in the other two will not get you anything because the cannot really do anything with mb of vram it only knows mb and mb from the documentation i have the quadra must get mo vram to have bit color is that correct yes this is correct you get to mb by putting k vram simms into the vram simm slots on the q s motherboard bonus question where do vram simms hide from the documentation they seem to be behind the power supply do i really have to take off the power supply to access the vram simms yup you have to take off the power supply it s only a couple of screws so you should be ok just make sure that everything is disconnected from it and watch out for static discharges

re why does apple give us a confusing message ubs carson u washington edu university bookstore writes bunt student tc umn edu monthian buntan writes does anyone know why apple has an ambiguous message for c regarding fpu in all mac price lists i ve seen every c has the message fpu optional i know from what we ve discussed in this newsgroup that all c have the fpu built in except the configuration why would they be so unclear about this issue in their price list i think this is mostly the fault of the people who write up the literature and price lists being confused themselves since there are two possible processor configurations and one of the them doesn t have an fpu it does seem to be an option even though it really isn t i m planning to buy the c cd pretty soon but i m now getting confused with whether it comes with fpu or not well then allow me to end your confusion the c only come with an lc in the base configuration if you are not getting this configuration then you are getting an fpu why say optional if it s built in good question i have been wondering that since feb th if you get the centris with cd configuration you are getting a mac with a rc processor that has built in math coprocessor support my understanding is that the optional fpu refers to your option of purchasing the centris without fpu or one of the other configurations with fpu this is possible but an option is something that you are supposed to be able to request when you want it what apple has done is given the buyer a choice between configurations and not an option apple does not offer an upgrade from the non fpu system to become an fpu system and it is unclear whether the processor on the non fpu system a lc can be replaced with a rc supplied by another vendor this is not unclear at all in fact apple has included in the roms of those machines with lc s code to recognize the presence of the full s fpu and use it thereby making the upgrade as easy as switching chips you pop the lc out and pop in a full apple did send a memo out at one point sating that the centris which only comes with a non fpu lc processor cannot be upgraded to support an fpu the pin configurations of the two chips apparently do not match so you cannot swap one for another again according to apple s memo they did i think i would double check this it has been stated countless times in this newsgroup by two of the centris hardware designers that the lc and the full are pin compatible and that the c can be upgraded to a full hades

re centris math coprocessor option david anthony guevara cup portal com writes sorry if this is a faq i don t normally read comp sys mac hardware i am purchasing a couple of centris s i configured the systems as follows eight mb ram ethernet mb vram math coprocessor option my purchasing agent told me about the math coprocessor option and sent me the apple summary documentation to prove it i ordered the coprocessor option but i m really not sure that we needed it i thought the chip had a math coprocessor built into it has apple had a math coprocessor chip architectured to keep up with the speed of the chip in the centris i am concerned that i may have set up a hardware bottleneck apple has really confused people with this whole thing i think we ll be answering this question for about the next year or so there is no option to get an fpu on a c what you have is a choice of cpus there is the lc that does not have an integrated fpu like the full and is only present in the base model of the c appleusa and there is the full which you get when you order anything other than the base configuration therefore since you have ordered one of the mb versions with on board ethernet models you will not be getting the lc but even if you wanted to have the lc you wouldn t be able to order a c with mb ram on board ethernet and an lc it s not an option also a note to people out there that have c s and c s thinking that there is an optional fpu the class chip cannot recognize an external fpu so there is no socket on the motherboard for a fpu chip and you cannot go out and purchase an fpu on a pds card or something like that the only way to get an fpu in these machines is to replace the lc with a full and if you have a c you will not need to worry about a heat sink if you do replace the lc with the full but if you have a c you do need to have a heat sink hades

re tcp ip routing localtalk ethernet in article qpn uinnjs stimpy css itd umich edu bchuang css itd umich edu ben chuang wrote here is the story i have a network with macs on localtalk one of them has an ethernet card and is currently connected to a next don t laugh i got it for the price of a mac iisi the next is connected to the internet over slip running on a baud modem currently we can telnet from the mac w ethernet to the next and then telnet out again to the rest of the world what we want to know is if there is some sort of hardware that will route telnet sessions from the localtalk macs to the next via the ethernet mac from what we have heard air doesn t do the trick software solutions would be good too but my impression is that there aren t going to be any our immediate interest is to be able to get to the next and telnet out again the slip connection doesn t allow us to assign ip numbers to machines so everyone shares that number oh well what you need is a hardware router such as etherroute tcp made by compatable systems this will allow you to connect your localtalk network macs to your ethernet network next and ethernet mac it will route tcp ip protocol between the two networks software routers are also available for less money but i m not sure if they work with tcp ip paul

full page pb screen hi i am working on a project for my marketing class and i d like to ask your help the assignment is to come up with a product and create a marketing plan for it technical issues are not terribly important at this point well my group s plan is to market a full page monitor for laptop computers it would be a third party product to be installed by authorized repair centers like newer technology s palettebook screen the idea is that the screen would fold in such a way that you would get twice the screen height of a normal screen remember technical issues aside in fact by adjusting the fold of the screen and the monitor configuration you could have regular or full height the screen would probably be monochrome the motivation behind this is that laptop computers seem to be very popular among business people business people also commonly use word processing and spreadsheet applications for which it is very convenient to see a large portion of the document because of the target users and applications color screens aren t really a neccessity we could hopefully keep the cost between and now please don t write this off as completely ridiculous i really need some constructive feedback so if you would please reply to me via email and let me know if you would consider buying a full page laptop screen how much you would be willing to pay for it any helpful commentaries on the idea also if you take this idea and make a lot of money off it doubtful but who knows please send me some thanks in advance mike

se hard drive problem i have an se with a meg hd which dates back to april when i originally purchased it i experienced the failure to boot problem this was fixed soon after by a rom upgrade on the hard drive lately a similar problem has been occuring when the computer is powered on the hd light flashes a few times and then i am given the no disk to boot from icon however upon turing the computer off and on again the drive always boots up just fine furthermore if instead of turning the power on and off i press the reboot button the same problem occurs but as i said turning the power off and on always works this problem is different from the boot problem in that before it often required several power off and ons to get it to boot does anybody have any suggestions as to what the problem is or how it can be fixed i m wondering if it s getting old and requires more time to come up to speed now is there a pram or scsi setting that allows me to tell the computer to wait a little longer before trying to access the hd thanks altan j stalker astalker nickel ucs indiana edu indiana university computer science dept
