Hmmmm...

I always thought these SIMMs had 2 1Mx4 DIPs (or DIL (Leg=
surface mount? or whatever they call em...)) and 1 1Mx1 DIP.
No one makes 1Mx3 chips. Mebbe they had a good deal on 1Mx4
chips and it was cheaper to waste the other 3 bits on one 
chip than buy 1Mx1 DIPs. 

Now.. does it really matter whether your SIMMs have 3 or 9
chips? 

btw.. does anyone know where to get "low profile" SIMMs?

I have a problem and a few general questions about the basic Sound Blaster card,
not the Pro.

I have the card installed in a no-name 386-40.  The card is currently set for
address=240 (not the default 220), dma=1, IRQ=7;  test-sbc works fine as does
parrot, fmorgan, and sbtalker.  I have two childern's games that use the card,
KIDPIX which works ok and "THE PLAYROOM" which doesn't.   "THE PLAYROOM" will make
certain sounds, but then will hang the system a other repeatable points.  There is
no hang if I tell the game not to use sound (but its is boring).

KIDPIX asked for the address of the card and I told it 240.  THE PLAYROOM didn't ask...
so could my problem be that PLAYROOM assumes the IO address is 220?  If so how does
it make the sounds that it does.

Now the general questions,  I know there is the FM part and the digitized part of the
sound board,  what makes what use of DMA, the io address, and the IRQ?

It's broken. 

Have the cards been pulled and re-seated?

Have the cards been swapped with known working cards or tested in working
systems?

Has anyone ever heard of Compex ENET/M Ethernet adapter? It is an

drivers are all there are on the supplied disk.

Does it emulate some other well-known adapter? I'm mainly looking for
a packet driver for it, but any information would be useful. The
WD8003E packet driver was able to dig the right ethernet address out
of the card, but it didn't do anything else.

If you can't afford a premium SCSI adapter, then you might as well go
with the IDE interface.  The cheaper SCSI controllers don't give
substantially better performance than a good IDE controller and\

Hi everyone!
I recently ordered a Gateway 2000 486 system, but since they
have problems with the 17" monitor ($195 upgrade) it would
take 4 weeks to get it plus the Telepath modem is not shipping
until May and I wasn't even able to order it, since, apparently,
it is not approved for overseas...
So I might cancel the order and buy from PCUSA in Walnut, CA
(800) 354-5566 which has a very good offer, too.
It's a 486-33 ISA with 8MB 70ns RAM (up to 64MB), 2 TEAC Floppies
245 MB 10ms SEAGATE (6MB data transfer rate), 256k Cache, 
Diamond Stealth VRAM SVGA, 15" MAG 15F 1280x1024 NI Monitor,
Focus 5001 keyboard, MSDOS, Windows, Mouse.

Price: $3050

The only problem is that I have never heard of PCUSA before.
Does anyone have any experiences with the company? They offer
a two year limited warranty and lifetime tech support. How is
their support? How long has the company been in business and
how's their reputation?

Any information is very appreciated.
Thank you in advance

Does anybody know of an ANSI driver that deals with 132x60 correctly?
Currently, the best I can find will somehow disappear the cursor when you CLS 
or otherwise tell the driver to clear the screen, and also 4DOS' SELECT and 
LIST commands seem to clear the screen to blackness, no cursor, and might 
possibly be functioning, or not, but neither of them are terribly useful 
blind.  Exiting them by hitting the escape key works normally, and they both 
work in other modes.

Anybody  else seen this problem?
Matter of fact, while I'm asking, anyone ever had problems with a Tseng 4000

I have a 33 MHz 386 with 64K cache form Myoda (from a Chicago suburb).
Overall, I am pleased with the computer, although I did have a couple problems.
The Chicony keyboard that came with it did not work And I had to go back
and have it exchanged. Later on, the mouse did not work, though this may have
been my fault. 

The speed of the computer is pretty good, though I am not exactly sure what
to expect from a 33 MHz machine (compared to other slower computers I have
seen). The speed of the VGA card seems adaquate, and as far as I can tell
it is very compatible (stuff that required a "100% compatible card or
100% register compatible card worked), so that should not be a problem.

The front panel provides a keylock, and a speed switch to switch "on the fly."
(I have the tower case, 4 drive bays, 1 remaining after 2 floppies and HD)
The 80 meg hard drive I have is 19 ms.

There is one weird aspect of it. The 5.25" drive can not be closed without
a disk in it, otherwise it will break. So I have to keep a disk in the drive
in case I close it. But overall, I would recommend it, even though there are
a few glitches I ran into.

You can can get RJ12 (6 wire) phone cable and DB9 and DB25 adapters
that the RJ12 plugs into. I've used this and it's fine for short
runs. I've got some doubts that a long run will work at 115kb. If
you can't find a local source call Dalco at 1-800-445-5342. A 100
ft. RJ12 cable costs $12.35 and the adapters cost $3.00 to $3.50.
Radio Shack sells the adapters, but not the RJ12 cable last time
I looked.

Considering that you only need to do it couple of times a week it
might be faster to ZIP the file onto one or two HD floppies and
use Sneaker-Net. If FASTLYNX doesn't do data compression, ZIP it
anyway before you transfer it.

Hello, netters; A question about CMOS batteries:

I aquired a new Taiwan made motherboard that has a NiCad cell soldered onto
the board, and still has the 4-pin external battery connector.  What is the
Nicad for?  I assumed that while the PC is on, the nicad would recharge and
provide power to the CMOS, regardless of the presence of an external Lithium
battery.  However, even after leaving it on all night, when I power down and
then power right back up again the CMOS is jumbled to the point it won't even
start a POST - I have to jumper a connector on the motherboard that's
supposed to drain the CMOS so it can start from scratch again.

So, then - what is the Nicad for?  Do I need to have a Lithium battery
connected anyway to keep my CMOS from scrambling every time I glance at the
big red flipper?  Or does the nicad recharge so slowly that overnight is
not enough?  Or is the Nicad for something else entirely?  Or do I have to
jumper the external connector somehow to enable the nicad????  And so forth.

Any help appreciated, email preferred.

My poor little AT clone is near useless now. I really need the memory

How much do 386 motherboards cost? Obviously I want to get a fast one,
but I'm not wealthy.

Are there major differences between the various cheap 386 boards?

Can I just drop the 386 board into my AT case and still use the same

Will I need to buy new ram or can I use my 80ns drams?

Is the installation easy or should I pay someone?

floppy cable), B: 1.2 MB 5.25 inch Teac floppy drive (middle
connector).  Floppy cable is twisted.  Both drives set for second
drive select (i.e. DS1 out of zero to three).

The drives seem to work OK, but should I have a terminating resistor
set somehow for one of these drives?  Which one?  Is there such a
thing as a terminating resistor pack on floppies?  Is it a jumper
setting (which is the only thing I can seem to find)?

Thanks in advantage for any help.
