[comp.sys.ibm.pc] Buying a 386

Ordania-DM@cup.portal.com (Charles K Hughes) (05/30/90)

  This has probably been discussed repeatedly here but I'm new to this 
group so I'm going to ask for the discussion again. :)

  I am planning on buying a 386 IBM-compatible computer.  I can put it
together myself so buying it in pieces is no big deal.  My question is
'what should I get?'.  I want the capability to run a decent UNIX.  I 
don't give a damn about OS/2 :).  I want to be able to use the various
disk utilities out there for optimizing a hard drive.  Things I would
like in my system - 3.5" & 5.25" HD drives, a hard drive 65 or 80 MB,
a VGA card (that supports the lower modes also but nothing above 800x600 is
needed), a Multisync color monitor (that supports 800x600), a standard
port card (2 serial, 1 para), and some sort of game card for games.
  My general uses are text processing, telecommunications, and (of course)
games.  CAD, Animation, MIDI, Drawing, etc are of no real use to me.
I do program - C, Assembly, etc - but I don't think this has a whole lot
of bearing on exactly what I buy.
  Given that and a budget of $2000 (preferably a LOT less) what mistakes
have I made above, in assuming what I want/need/can afford?
  A more specific question is - what would be the difference to me, apart 
from speed, of buying a 386SX-16MHz compared to buying a 386-20MHz.  I
do not intend to buy a co-processor (unless they get as cheap as a surplus
ram chip :).

Thanks

Email is fine, but I think others in a situation like mine would prefer
you to post.

The price of SX support cards will be much cheaper due to the narrower bus.
I think you may also be able to use off-the-shelf AT cards until SX-specific
cards are made.			-ted-

There are no (as far as I know) any such thing as 386SX specific cards---all the
386SX computers that I have seen use the AT ISA bus. The whole reason
intel designed the 386SX was so that 386 computers could be built easily
and use AT equipment, memory, etc, and to keep the price real low!\

The other two buses are the Micro-Chanel and the new but AT
compatible EISA bus.

20mz 386sx's are just being announced now, so that may be a better 
choice than a 20mz 386.

The second point noted is true in nearly all cases, and holds true for
true 80386 systems as well. I'm running a ZOOM 2400 XL in the 8-bit slot
of my NEC Powermate in addition to an Intel Above Board 286 (sic). The
NEC is no great shakes as a system, particularly due to its appalling
approach to memory upgrades, but it's given me no compatibility problems
to date. And, since the SX uses the 16-bit AT bus, what would make something
SX-specific?
