[rescue] Need motherboard for IBM RS/6000 42T

[leaknoil]

I found an old 42t thats in great shape other then it doesn't work. Just 
says 212 on the front display and nothing else happens. Looks like a 
memory system error of some sort. I'd really like to get it working again.

When I first tried turning it on it went past the 212 display and seemed 
to be going through it's normal diagnostics. It would always seem to 
stop at some number though. Most of the time it was 212. Never got 
anything on the monitor but, I think the 13w3 adapter I had wasn't wired 
right for this.  After a few more boot tries it just went to 212 as soon 
as powered on and stayed there. I opened it up and there was a simm 
hanging half out of the socket. Reinserted it but, still 212. Played 
with taking ram out and moving it around and no change. I imagine it 
probably took out the motherboard.

Unless anyone has an idea what else it might be I suppose I need to 
replace the motherboard. Anyone have a motherboard they can part with. ? 
I suppose I would be interested in a whole 42t if taking the time to 
pull it out is a hassle. I'm in California but, shipping a motherboard 
from anywhere in the world probably isn't out of the question. Shipping 
a system from outside the US probably would be. Any help appreciated.

Total off subject but, I also need to find  MPE on dat for a HP3000/957.
