My EISA one does not have a 16550 UART

My EISA motherboard has only a socket for a Weitek chip, no overdrive, no
pentium.

No it's on the EISA Bus. There is no local bus on the EISA machine.

The EISA has 8 SIMM sockets for 2,4, or 8MB simms (in pairs only)

>What is the cost of a single 16MB simm upgrade?

Who cares? it won't run on the EISA model. You need 2 8MB simms; but my
question is.. why buy upgrades from Gateway? They are in the box business, not
the chip business. Chips will probably be cheaper on the open market.

Also, unless you are going to load the system down with either large-memory
requirement scientific research programs, or lots of network software, 8MB is
sufficient for running OS/2 with 4-5 DOS or windoze apps simultaneously. At
work, I have 16MB memory, but I am running IBM's TCP/IP for OS/2 and will be
adding the NEtware Requestor for OS/2 in the near future. That kind of loading
requires lots of memory - the more the better. At home, without the networking
stuff, 8MB is fine (OS/2 2.0 in both places).

A lot of problems with large (>14 inch) monitors is due to external magnetic
fields... The easiest way to test/fix them is to turn them on, wait a few 
minutes, turn them off, wait a few minutes, etc... This allows the degaussing
magnets to "adjust" the screen to the external magnetic fields...

If this doesn't fix the problem it should be aligned where it is being 
operated to cancel out any residual magnetics (the earth's field is the worst)
This should fix a good monitor, and make a bad one tolerable...

NEC no longer makes the 4D or 4DS line. You can however buy one of the last

Even though IBM and the other brand-name x86 manufacturers have called

the original IBM PC?  Isin't there enough similarity between that "PC"

Don't they already have their own groups, with the names Amiga, etc,

(comp.sys.powerpc.*) so I don't see how it confuses the situation.

From: akhran@krypton.mankato.msus.edu (Scott V Buresh)
Date: 21 Jan 93 21:18:47 -0600



  Well, here's a question I'm almost sure has been asked before:  Can
you have a SCSI drive, specifically a Quantum prodrive 210S, and an IDE,
a Seagate(107 MB,I forget the #) with a DTC 3280AS SCSI host adapter and
a no-name(think Toshiba chipset) IDE card co-existing in the same system?

  We have the drives set to different IRQs (11 and 14) and their ROMs 
mapped into different address spaces.  The SCSI is set up as type [none]
and the IDE is type 47+ (custom).  The system is a clone 386sx-25(AMD chip)
with a Soundblaster and Diamond Speedstar 24x VGA card.  We can get either
drive to work alone, by making it drive 1 and setting the CMOS so the other
one isn't listed.  We would like to keep both drives in the system
(obviously :).  Do we have to make the IDE a slave drive?


   Has anybody done this sort of thing?  All replies/comments are 
welcome.

Hmmmm

What is "big bucks" here? How much more will a local bus IDE
paddle card cost compared to an ISA one? I thought one endearing
feature of local bus is supposed to be that it is cheap.

My guess is that if you want a small Novell server you'll see the 
benefits of local bus IDE, otherwise you'll only notice it at some
times (eg when loading apps).

I'm surprised at these comments about the recent (future?) release of the

that was advertised in the December BYTE.  They offer a 486/33DX machine
with VESA and the Viper card at a price point comparable to a Gateway 33SX.

Anyone have general comments on Comtrade, specific comments on this machine,
or speculation on whether they're counting snakes before they hatch?  We're
tempted by the until recently unblemished Gateway name, but if we can get
this much more performance at the same price, we'll find it very hard to
resist.  I'll summarize to the group if there's sufficient interest.

I own the 550i.  I may be wrong because its been four months since
I studied up on these two devices.  So with that disclaimer stated,
I *think* the only difference is the tube (Sony Trinitron) on the 560i.

This is a very difficult practical problem because of the history of
the parlance.  On the sofware side one solution has been to use the
word msdos instead of ibm.pc, but how can we do the same on the
hardware side so that it is nether too narrow or too broad, because
both will invite problems.

Hi, 

 I am thinking about getting a second IDE hard drive.  My current configuration is
that I have 2 floppies, and a single 80Meg (18ms) IDE hard drive.  Is it pretty
simple to get another IDE drive and plug it right in?  I heard that I may have to
worry about putting the faster one as the boot drive, or something like that.

 Also, I am thinking about getting a tape backup drive.  Does anybody have any
good recommendations?  Things that I'm concerned about are:
	* Speed
	* Price (of course!)
	* Being able to easily plug it into my system
 The last point above is crucial.  Does these tape drives come with their own 
card, or do they plug into the existing card (mine is going to be full), or can I
use one of those fancy parallel port SCSI devices?

 Any help is much appreciated!!  Please send replies to 'gt8389a@prism.gatech.edu'
or post a follow-up article.

 Thanks again,

If America uses common TV cabling, this should have 75 Ohms impedance,
