I've already posted this to the PS/2 newsgroup but thought I'd drop it in here
too just in case - I believe the machine in question is old enough (or odd
enough) to qualify.
Basically I'm in the process of restoring a Model 50 I was given recently and
was wondering if anyone could point me at a technical reference guide for the
machine?
I also have a couple of questions.
1) The machine contains what I assume to be the hard disc controller, what
capacity/type of drives will the machine accept - and where can I get one?
2) Can the machine accept 2.88Mb drives (this one is purely out of interest)?
3) There is an expansion card with no markings on installed in the slot
farthest away from the PSU. It is connected to what appears to be the
processor socket ('286 right?) by a section of flexible PCB.
The card has a daughter board attached which is about half as long as the
card. The visible part of the main PCB contains three (empty) 72-pin SIMM
sockets.
Any ideas on what this may be (some sort of turbo board, 386SX upgrade, etc)?
Was it fitted as standard or was it added later?
4) The "paddle" on the power switch has been broken off. Can I get a
replacement switch or do I need to get a new PSU?
Thanks.
TTFN - Pete.
