     thank you.

 That requires an expansion board, right? The little info I can find
 suggests that 3 2M SIMMs is max, onboard. 
 I thought I was the only PS/2 fan here :P 
I was one of the developers who worked on Linux/MCA.

  Depending on the model of your board, you could
have a max of 6mb or 8mb.
 To add more memory, you would need an expansion board. One of the better
 boards I that I used to use in model 60 machines was made by Kingston and
 took up to 4 72pin simms. 
I believe the BXX series could do 16 MB on the board.  Plus the 72-pin
SIMMs weren't your standard plain-vanilla ones.  They had PS/2 Presence
Detect (PPD) feature on them.

  One of the best non IBM references I ever found
for the PS/2 line is a
 book called "Upgrading and Repairing PCs", written by Scott Mueller, and
 published by QUE. The last edition that had the PS/2 info in it was the
 4th edition. I never owned a hardcopy of the 4th edition, but I have an
 electronic version of it that came on cdrom with the 10th edition. I
 completely wore out my 2nd and 3rd editions of the book. (If anyone has a
 4th edition in good shape that they don't want, I'd be more than willing
 to pay shipping.) 
I have a better source.  I have the internal IBM technical manuals and
schematics for every PS/2 ever made, including rare ones like the N51SX,
and the 43SL.
