The UART on PS/2 Model 80 computers is integrated into a VLSI chip so it
is not user-replaceable.

There are four different UART types used on the PS/2 Model 80.  You can
tell which type is used by the part number of the computer (8580-xxx):

-041, -071
NS16550 (FIFO mode not normally enabled)

-111, -311
NS16550

-081, -121, -161, -321
NS16550AFVV

-A21, -A16, -A31
NS16550AFVV (supports DMA transfers)

Note that this list only applies to the integrated serial port on the
planar board of the Model 80.

But how much data are you likely to get out of a cache? If you have
a meg or more then sure, local bus or EISA will be beneficial. For 256k,
the benefit is less visible. Granted that most controllers with cache
offer large sizes, the point remains: the cache only helps on a hit,
and transfer speeds return to normal on a miss.

I've seen very few large ISA cached controllers in any case, so the
whole debate may be academic.

I am looking for information about the Wangtek 5525ES tape drive.
I have the following questions:
1) Is the 525MB only valid if data can be compressed (such as text files) or
    is it a "real" 525MB capacity?
2) What lower density formats can the 5525ES read and/or write? (For example
   60MB, 120MB, 80MB, 150MB, 250MB etc)
3) What drivers are available (ISC 2.2, ESIX 3.2D, Dell, Destiny, etc)?
   What features have these drivers? Do they support all the modes the
   hardware is able to do (see question 2)?
4) Does it work reliably with the Adaptec 1542B?
5) What does it cost at the moment in the US? You know we have a quite
   low dollar exchange rate at the moment :) I found only one offer
   in Computer Shopper ($899 for the bare drive).

Thank you in advance.

The modem doesn't receive and respond to that string.  It sends it
when it detects loss of carrier.  Moreover, as has been pointed out,
it sends it mainly for the benefit of the user, as the terminal
emulation software should be detecting a hardware indication of the
carrier which is also sent by the modem.

If that string causes problems, the software is at fault.

Need help! 

My 2 year old 386 25Mhz fails to setup its CMOS to recognize
a 212 Mb IDE hard-disk from Western Digital. The BIOS is :
  
    386 Modular BIOS V3.02 from AWARD

Questions:
1) Is is possible to upgrade the BIOS with a newer type, which ?
2) What would be the cost of the operation ?
3) How do I contact the AWARD people ?

Norbert Jaffa's encyclopedic disseration on math chips ("What you always

August 1992 of its 38D87 chip with another (slower but more accurate) chip.
This chip is marketed in Europe as the 387+, but here in the US is still
called a 38D87. Since I bought my Cyrix 387 in August of this year, I have
no idea which chip I really got, the old one or the new. Two questions:

1) Can I tell by inspection (markings) or operation (results of instructions)
   which chip I got?

2) Any speculations on the reason(s) for the switch? (Copyright violations or
   mask change to reduce manufacturing costs?)

Any informed information will be appreciated. If email volume warrants, I

I bought a gateway. I am  on my third monitor, my third video card,
and my second power supply. I updated my video card and was charged a
thirty dollar *restocking*  fee for a defective part. People I talk to

supply is functioning normally?

In short: Some idiot sold me a motherboard over the phone.  Motherboard
doesn't work.  Idiot (still over the phone) insists that the power supply
is "non-standard" (he uses the term as though it was magic) and insists
that I give him more money to "fix" the problem.  I try to take him to
small claims court.  The slime hires a lawyer who seems to have specialized
in obfuscation in law school.

I have an analysis of the power supply from an impartial third party.  The
impartial third party says that the voltages and ripple voltage are all
good.  No spikes.  The idiot and his lawyer are certain to claim superior
knowledge and say that the numbers are too far off (or something).

The question then is this: Where do I find the ultimate authority on what
constitutes a bad (or a good) power supply?  Is there a reference book I
could get?  Someone I could get a letter from?  I need to nail this idiot
good in order to get my money back.  Any ideas?

I find it hard to believe that your modem sees that string and hangs
up the line for you.  I suspect it's probably more like some slimy
terminal program that looks for "NO CARRIER" instead of watching the
DTR line like it should be doing.  Try switching terminal programs
and read that article again.

The name of the product is The Complete Communicator.
It is manufactured by a company called The Complete PC.  I got one at a
Sam's Club for $200 about a month ago and love it.  I have seen them in
Egghead for $399.  It is an answering machine, fax and 2400 baud modem all
on a single card.  It is more than a basic voice mail system.  It can
handle up to 999 mailboxes and automatically forward messages to any number you
specify.  Also the modem and fax can have their own mail boxes.  With this
capability a caller can leave a voice message, fax a message or talk to the
computer via modem (assuming their is bbs software, etc running).  All this
can be accomplished with a single phone line.  There is even Windows
software so that it may be controlled from Windows, including sending
faxes.  Also, it can be controlled remotely from any touch tone phone so
that message may be sent out if desired.  There are too many functions to
describe here but it is well worth the price.  I highly recommend it.  PS
I don't work for The Complete PC.

Sure, Centronics (printer) type parallel ports come in three flavors:

The earlier kind, which for some reason won't allow you to connect a device
like a parallel port hard drive - I don't know the specifics, but these
critters are rare these days.

The "standard" parallel port and "bi-directional" parallel port.

On the "standard" type there are eight output only data lines which can
send a byte to the device and four input only status lines which the device
can tell the computer what's happening (busy, out of paper, etc.).  For a
storage device, the computer sends a full byte at a time.  However, it can
only receive a nibble (half a byte) at a time by reading the four status
lines.  The storage device sends two nibbles via the status lines which the
device driver reassembles into a byte.

For a "bi-directional" type of port, the eight data lines can both send and
receive data a full byte at a time.  Bi-directional ports are standard on
IBM's microchannel machines and slowly gaining popularity in the clone
market.

BTW, in theory, a device driver that uses the status lines to get data from
the storage device should work with both standard and bi-directional ports,
however these drivers have some problems with bi-directional ports.  If you
have a machine with a bi-directional port, contact the parallel port
storage device manufacturer for a device driver designed for the
bi-directional port.

Yo !
This is the deal, a few weeks ago I bought my father an old 286
without a harddisk. I also got him a HD and controller card but ....
I've tried to install, configure, or what you call it, but it refuses
to work. The HD is OK (checked), the controller card is OK (not checked)
 The 286 is a SPERRY and it's a kind of funny pc. 
It will only boot on a special dos 3.3 from commodore.
Anyway, the HD is a miniscribe model 3425, the card is an adaptec ACB2002
and the pc is thus a SPERRY 286. When I try to configure it it
gives me the message - ERROR READING FIXED DISK.
Is there anyone that have any ideas ?
It would be greatly appreciated !

What you'll get is an expensive 720KB drive. 1.2MB drives use 80 tracks,
360KBs 40, so you double the capacity. What you won't get without
a suitable driver (not DRIVER.SYS) is double stepping (except for some rare

Apart from that, you can always patch you controller (details if you email me).

No.  You leave the irq9 signal *alone*!

I would suggest the following procedure for disabling use of IRQ2 by
VGA/EGA cards:

1) Most modern boards of the just-above-bargain-basement-price-or-better
ilk have a jumper that can be opened to disable use of IRQ2.  Check your
board's documentation, or look for a suspicious jumper.

2) Most of the boards that *don't* have a jumper have a special PCB
pad that is specificly designed for cutting.  Again, check your board's
documentation, or look around for such a pad.

3) The IRQ2 pin is the fourth pin from the rear pannel on the non-component
side of the board.  You can try to trace it, say using a stylus or your
finger, to see where it goes, but with complex multilayer boards this is
not easy.

4) If you must cut the trace to the IRQ2 pin (because you fall into
category 2 above, or because you don't even have a special pad), do the
following: 
  a) Select a portion of the trace near the IRQ2 pin (so you can find it
  later) that is not excessively close to other traces (so you don't
  accidentally cut them) where the trace runs straight for 10 millimeters
  or so.

  b) use a single edge razor blade or xacto knife, and cut perpendicularly
  through the trace in *two places* a milimeter or two apart. 

  c) Then *lift up the copper* between these two cuts.  This assures that
  the trace is actually opened.

*disclaimer* :  Should you, doing the above, cut your thumb off, ruin your
board, or become late in your taxes, don't blame me.  Your life is *your*
responsiblity!
