I spotted this PS/2 at local store pc reseller/repair and watch/clock
combo store (One block away. cute!) from trade in, offered $40 CDN
(accepted, will pick it up with cash in January, cuz I'm strapped
for rest of this month.) for whole thing (keyboard included maybe?)
Clean condition, just a blue button floppy eject missing which I can
repair.

I know this an MCA bus and I do have small collection of MCA cards.
(Dual async 16550AFN card and minor other things.) I do not know
which motherboard type 1 or 2 yet. Both type 1 and 2 used either
16mhz or 20mhz version. I happen to have 386/387 20mhz and Rapid CAD
set. Did this boards used different one OSC chip used for each 16mhz
or 20mhz? Because I'm considering hopping it up to 20mhz this way by
this OSC swap and pull the original cpu just in case if's buggy
batch. I'm still looking for a Axx 25mhz with or without 486 upgrade
platform motherboard (TYPE 3, and it's 64k cached BTW.) for this
model 70 IF the price is still cheap. :))

If you have any info or comments, as I'm focusing on getting most
performance out of it. So I welcome yours words. :)

One side comments:
I also have a model 50Z motherboard to play
with too. This board is one of fastest 286 that IBM ever designed.
It requires 85ns or less to work properly in 0 wait state mode. But
dumb thing that IBM did was limit it to 2mb max. (!!) Therefore,
requires proper fast memory expansion card in MCA slot to get 16mb.
Oh, this stupid 16mb limits happens with all early PS/2 286, 386dx/sx
and early 486 still limits to 16mb with a card because IBM usually
limits about half of this. :(( Is Model 80 is free of this silly
thing?

Dust off your trumpets and drums and start a big racket, throw
tinsels: This model 70 WILL hit 10year mark this January, fitting
timing!
