[comp.sys.ibm.pc] microchannel memory

guarna@uicsrd.csrd.uiuc.edu (06/08/89)

I am trying to locate a 32-bit, microchannel add-on memory board (4 Meg)
for a 20 megahertz PS/2 Model 80.  The IBM boards are a bit pricey..does
anyone have anyone have any experience (either good or bad) with
other vendors' products?  In particular, I have been considering
something like an AST Advantage 2/386 with "low-cost" SIMMS from
one of the mail order places.  Is this asking for trouble?
Any review articles that I might be able to read?

I have an IBM MCA expansion board type 6450367, with 2 megs on it.
It takes three little daughtercards each with 2megs, for a total of six 
megs possible. The thing died when an IBM repairman replaced the
motherboard of my 16 Mhz Model 80. It took three days, four service
calls and a near resignation on the part of the serviceman before it
worked again. A couple of weeks ago it died again. This was after our
on-site prepaid warranty ran out- -but the board itself had a carry-in
warranty. It took a week to get a new one ("they're back ordered
to Jupiter - they all die"), but luckily it works now. And I
so far have not been able to get another source for the little
daughtercards. Our computer store sells them (2 megs) for $984.


So IBM cards, at least this kind, suck also. 

If anyone knows of a source of daughtercards for the 6450367, please
post the info.
