  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? 
you can only use drives originally assigned to the machine unless you want to 
go scsi external...
...

  2) Can the machine accept 2.88Mb drives (this one is purely out of  interest)?
...
   no. not supported. 

...
   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)?

run peter wendt's adaptor card id'er program. goto 
http://members.aol.com/mcapage0  the program is listed on the ps2 support 
page he has.

only way to fix is replace ps from a parts machine.

  Thanks.

    TTFN - Pete.
