I'm an MCA freak and have a good majority of the PS/2 models. The
IBM internal SCCI connector was 50pin and some models had
onboard SCSI as you likely know.
I checked my archives and got this from an MCA AboveBoard thread
I culled from the PS/2 newsgroup. No mention in the thread about a
50pin connector tho. Mainly about getting the memory recognized.
The memory chips were as you describe.
ftp://download.intel.com/enduser_reseller/above_board_memory_boar
ds/abmc.exe
Includes the SOFTSET.exe utility
It came up blank and the archive no longer had the enduser_reseller
folder. Some zealous employee must have seen the reseller title and
deleted it. Blast !! That means the Softset.exe is also likely gone.

Most early PS/2s had a 16MB limit from the 8580 on, but there were
workarounds.
