Hi all,  Has anyone heard of this board? It's a  486DX2-33/66.   If so, does anyone know if it will work with BSD or Linux?  A local PC vendor has this.  He says it's a U.S. brand.  Please e-mail if possible.  Thanks,
Does anyone have any experience or is familiar with the Cardinal P9000 VL-Bus graphics card?  Would appreciate knowing what you think of its capabilities.  Thanks.

I need info regarding a miniscribe 3.5" half-height drive. There is a sticker on it with the following,     MODEL   HDA    PCBA   UNIQUE   TDA     8425F   09AA   03AB   03AA     - But the sticker on the biggest chip on the MFM interface has this,     MODEL   PCBA   TDA      FXX    03AB  What is the spec of the drive (# of cyl, heads, etc)? How fast is this drive? Can I use it as a RLL drive?  I also have a SCSI interface that seems to match all the connectors for this drive. It has this description,     MODEL   PCBA   E-P   TDA      AXX    01A    29A Can I replace the MFM interface by the SCSI interface and use the drive as a SCSI drive? What would the drive size be? There is a set of jumpers on the SCSI interface with "6SEL" besides it. What is the use of it?
Help!   I'm trying to configure NCSA Telnet v2.3.05 to work with a 3C503 ethernet board.  I can use FTP fine, but whenever I attempt to use Telnet, the machine hangs with a blank screen and a blinking green cursor.  Any ideas?
I was just reading in PC Magazine that the peripherals in a PC with an ISA bus can only access 16MB of memory.  Also, that some video cards on the ISA bus look for a memory aperture to map their memory to.  So that if I wanted to put 16MB of memory on my PC, my video card wouldn't have anywhere to map it's memory to.  Can someone explain this in more detail.  Is there a way around this limit.  If you email me a response, I will summarize. 	-Bo	begolej@csgrad.cs.vt.edu
I am looking at getting a laptop for work and I was trying to decide between the Toshibas and Gateway's Nomad.  The price is about the same,  but the Gateway has significantly better performance (200MB vs. 120MB  hard drive, 50Mhz 486DX2 vs.  25Mhz 486SL) and much cheaper accessories  (extra batteries, modem...)  The concern I have about Gateway is the durability and reliability. Does anyone out there have any experience with the Gateway Nomad?  Thanks,

I think it all depends on your motherboard and the cards you have in your system.  Your HD stopped boot probably because your HD controller can't handle the faster BUS speed.  I have a 486-33DX, I set my bus divider to CLK/2.5, that is close to 13MHz.  I can gain singificant performace increase on my Video card and harddisk transfer rate when I boost the bus speed.  And my system work flawlessly under this setting.  And you know what, when I go to CLK/2(17MHz BUS), my HD refuse to boot.    Just my 2 cent.

Husak - husak@ux1.cso.uiuc.edu - Univerisity of Illinois  Does it do it to all tapes?  Were the two tapes that it unwound of the same type from the same batch?  The reason I ask is that I bought some generic tapes that did this and found that the tape markers were not fully punched out and had closed the little marker hole.  It was only on a few tapes of a set.  Did you open up the tape cartridge and put the tape back on the reels?  If you have not yet, open it up by removing the two screws on the bottom of the tape cartridge and snap the plastic shell away from the metal base.   As you are pulling the tape through the assembly try not to touch any more  than you have to.  As you are doing it, look for a couple of little holes in  the tape.  These are the marker holes which let the tape drive know when it is  at the end of the tape.  The holes are spaced a couple of inches apart.  My best guess is that the drive finds the first marker and then stops on the second marker?    Anyhow, If the tape has the holes, then check to see if the mirror on the tape is clean.  The function of the mirror is to detect the marker holes.  The tape drive shines a light at the mirror and has a pickup in the area where the reflection would come out.  When the hole goes by, the pickup detects the  light that was allowed to pass and it knows when to stop.  If the mirror is dirty or out of alighment (unlikely since it is made into the case) you might have a problem detecting the end of the tape.  If the tape drive does it on all tapes and the tapes all look good, then either the pickup or the LED of the sensor system has failed or is dirty.  If you open the drive door you will see the sensor assembly to the left of the R/W head assembly.  If it looks clean and nothing is in its way, then the drive may need to be serviced.  It is possible that the LED is burned out or the sensor is out.   If it is still in warranty, you might be able to send it back to CMS for repair.   --- Scott Hiles whiles@relay.nswc.navy.mil

I ended up having to destroy the connector, put heat shrink tubing on the individual pins and  then plug them into the SB connector in the correct order.  It works great  this way so this turned out just fine.  It certainly sounded easy based on other people's experiences but my attempts did not go too well...

It's an interesting idea, but the worst-case data patterns developed to test magnetic media are totally different than the patterns used to detect common faults in memory chips.
In case anyone was wondering about upgrading their 386 or 486 class machine without spending a lot of money, I looked into replacing the processor on those machines and here are the facts (as I understand them).  If you have a PS/2 Model 70 or Model 80, you can replace the i386 chip with either 1) a Cyrix 486DLC chip for $130 which will increase your processing power by about 60% for normal fuctions, and not at all for math functions. This chip will only run at your original clock speed, ie. if you have a 16MHz machine the Cyrix 486DLC will run at 16MHz. note: Windows does not use the math functions, so it is a good upgrade if you are running Windows. Or, 2) you can get a Kingston 486/NOW platform for $450 with a 25MHz i486SX on it which will increase your normal processing power by about 100%, if you were running at 25MHz originally. But again it will not increase the speed of your math fuctions.  I think that it will continue to run at 25MHz even if your original processor runs at a slower speed. There is also 3) the Kingston 486/NOW platform for $750 with a 33MHz i486DX on it.  This might speed up your math functions as well, but I am not sure.  If you have a PS/2 Model 70 B21 or other PS/2 machine with either an i486SX or a non-clock doubling i486DX (ie. it runs at either 25 or 33MHz) in it, then you can get an Intel Overdrive chip (which is really an i486DX2 chip) and replace your chip with it.  You should get about 95% better preformance for both normal and math functions.  The 25/50 Mhz version of the Overdrive chip costs $450 and the 33/66MHz version costs $700.  The replacement for the 25MHz 486SX chip is an espeacially good deal as it provides the math coprocessor which the 486SX does not have.  Note that the speed ratings on the Overdrive chips are the maximum speed at which they can run.  If you have a 20MHz 486SX, then the Overdrive chip will run at 20/40MHz, ie. 20MHz externally and 40MHz internally.  There is no reason to buy an Overdrive chip which is rated at faster then your machine, you will not get faster performance.  You should be able to buy these chips from any of the microchip merchants that advertise at the back of PC Magazine or PC Week.  You might want to shop around as prices do vary.  If you need a name/phone number for a source for a particular chip, e-mail me, and I will respond with a couple of sources.  Lawrence Khoo
