	Umm, excuse me, but what it sounds like, is that you're implying the
lack of parity bits in the memory on Macs is the reason that Macs can trash
the OS when they're not shut down properly.  This is simply not true.  The
reason is that the Mac uses a higher performance file system, and buffers and
caches stuff, with MS-DOS doesn't, so, if you shut off a Mac before it writes
out the cache, or during a write, you can hose things up.  This has nothing
to do with parity memory, and everything to do with the OS.  Unix is the same
way, for instance, I run Unix (Mach386) on a 486/33, I don't dare power the
machine down without doing a shutdown.  And, I assure you, the memory in my
486 is parity (1X9 SIMMS).
	I realize that this is getting off the proper track for this newsgroup,
and it's possible that I misread this, but I just couildn't let it stand the
way I read it.

There are other reasons besides IBM and Microsoft gobbling diskettes.
OEM's are shipping more PC's with 3.5" drives then ever before.  This
number is expected to increase as more desktop, portables, and others
use these drives.  Consequently, YOU GUYS, i.e. consumers, are also
partly responsible.  You need disks to feed these drives.  Finally,
none of the manufacturers anticipated the demand.  Same thing happened
when 5.25" HD diskettes were in short supply 4 or 5 years ago.

The greatest shortage lies in bulk media.  This is typically the media
duplicators and developers use to duplicate their product.  Why?  More
money to be made labeling these disks and selling them over the counter
in pretty boxes to consumers.  This drives up demand even more since
duplicators and developers try to hoard whatever supply they get.

It's tough everywhere, even in 3M.

It *would* be an Intellish thing to do, but nope: there is one for the
sx, and one for the dx.  More accurately, there is the P23T, which
plugs into the upgrade socket (found only on 486sx motherboards,
AFAIK); and there is the P24, which is pin-compatible with the real
486.

People have suggested that speed-sensitive BIOSes may bogue out at

Generic CADD can output DXF files.  That isn't a standard defined by an

Followup-To: comp.sys.ibm.pc.hardware
Organization: SCRI, Florida State University

Since there have been several threads involving the purchase of
386 motherboards on the net lately, I thought it might be beneficial
to report on my latest purchase.

I bought a 386/33 motherboard from System Dynamic Group (800-373-6467).
The price for the board was $265, and I had them put 4 megs of memory
on it, at $40 a meg.  Total 265+160+5 shipping.  Took five days to get
here, from the time I phoned in the order on a credit card.  Sent UPS
and nicely packaged.

The board is nice.  It is a mini-AT board, with 64KB of onboard cache,
an AMD 386DX, AMI Bios, no numerical processor.  The only drawback is
that it does NOT have a 32-bit slot.

I had an old AT (original IBM) with a 286 on it.  I pulled the motherboard
out of there, slid this one in, transferred the I/O boards (FDC, video,
serial I/O and an ethernet card) plugged the floppies and hard disk in, and
it came up running like a champ.  I let it run tests all night, and it was
still going the next day, and has been running ever since.

I have no connection with the company, other than just as a satisfied
customer.

There is an easier way to do it with a little help.  The help comes from
another type of video board.  It must be a different type than what he has.  If
he has VGA get a CGA or mono board and monitor.  EGA is not different enough
(same setup type).  When the bios detects the different board it will get upset
and jump to the setup.  We had to do this at school a few times.  

Have fun!

Is this the same as DMA?  Does it go beyond DMA?  With DMA the CPU still
needs to start transfers, but doesn't have to filter through all the data.

My bet is that your i/o card is set up with the same IRQ for COM1 (your mouse)
and COM2, your modem.  It' likely that they are both on IRQ3, because most
modems don't let you change the IRQ corresponding to the various COM's.

Open your box and check the jumpers on the board.

known if there are any problems with Stacker 2.0 but I'm using it personally
on a 386-25 with qemm 6.0 and a soundblaster 1-1/2 both with and without
smartdrv. Your motherboard should have one switch or jumper for the monitor
type (close to the power plug?) but that usually only reports a bios setup
error if it is in the wrong place.

I recently bought a used 20-MB Irwin external tape backup, and
I've formated the tape.  The Irwin had no documentation.  The
software, EzTape 2.2, had the Compaq logo welcome screen.  I have
no idea what the model is.  The tape I formated was a DC2000.  I
don't have a bulk eraser.  I tried using a speaker to erase it,
but it didn't work.  The data, formating, and servo track
remained intack.  I've been going around town looking for a bulk
eraser.  So far, the only place I found one was at Radio Shack at
$50 Canadian.  If I find it at another store, it'll probably cost
$25.  I'm going to keep looking.  (I hate Radio Shack.)
 
My advice is to buy a DC2000 and see if it works.  If it works,
that means the DC1000s don't work on your drive.
 
I'm going to write Irwin and see if they provide documentation on
my machine.

I wonder, would you rather have you hardware when someone tells you your going
to receive it, and it won't work, or wait for it to be work and receive it
much later.  I ordered the modem also, but I don't really care that they
are delaying shipping orders due to problems with the modem.  The price is
great , and I think it's worth the wait.

Running DOS on a system like yours is nonsense. Try out OS/2 2.0,
which has just been released. I do not think you can use PC-anywhere
(I am not sure), but you can take advantage of the power in your
system in a way you can only dream about with DOS. Join the
comp.os.os2.misc group for more informataion. Get the OS/2 FAQ list -
you will find the instruciotns in Timothy SIpples signature.

	Just call Always and order the VCN-1.02 ROM and place it in the
controller This supports > 2 hard drives with DOS 5.0.  With other OS's I don't
know.

	Ok.. I have this super cool zenith flat screen monitor.. its a perfectly
flat screen with a brilliant anti-glare coating.. However its only 14" in
size and can handle 640x480 maximum..
Does anyone know if Zenith manufacture screen similar to these with larger
tubes and higher resolutions.. preferably 1024x768.

Thanks
