I have been working on an IBM PS/2 Model 80 (8050-071) today  and 
have  encountered  a few problems. These are  listed  below,  but 
immediately  I am after a second hand 486 Motherboard  which  can 
replace the one currently in the PS/2 80.

Current problems are:

1) When I boot, I get an error 2401 *unless* I leave the SVGA
   monitor unplugged and plug it back in after it has done the#
   POST

2) The battery is flat/gone - what should be on the speaker
   assembly? Any old lithium battery?

3) There seems to be a problem with the "Video Graphics Array" 
   cicuitry. I get an error 00240900 during the diagnostics
   of the video

4) There are two IBM Memory modules plugged into the board, each
   is 1MB. One of the pins on bank 16  (motherboard  side)  is 
   broken, yet the POST reports 2048K OK.....

5) Are the modules in 4) the sum total system memory?

6) Are MCA SCSI-2 cards easy to come by?

7) Has anyone got a suitable IBM PS/2 Model 80 486 motherboard with 
   SVGA onboard they are prepared to pass on/swap??
