I have an MCA board here (probably pulled from a PS/2, but I really am
not sure where it came from).
Its marked as an Intel Above Board MC. And currently has 8 30 pin SIMMS
on it (1 MB each it looks like). From what I can find, I think this is
just a normal above board memory expansion card (max 32 MB?)
However, there is also a 50 pin IDC connector on it. Is that for
connecting to a daughter card? I just want to confirm that fact, and that
this isn't really some kind of a SCSI controller with a nice buffer on
it. I thought the Above Boards were just memory cards, but you never
know. (maybe if I could find something about them on Intel's site... but
their AboveBoards support section seems to have vanished)

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.

Hi - somewhere around this mess of equipment in my office/computer room
(though i cant find it at the moment) i have a Wang 286 - not MCA - that
i upgraded long ago with an intel Above Board and and an Inboard 386 and
i seem to recall there being a connector that gave the Inboard 386
processor direct bus and memory acess to the Above Board instead of
having to go through the usually slower system bus - hope this bit of
info is correct and useful to you -billp

I have an Intel Inboard 386/PC installed on one of my IBM PCs and a
bunch of docs and programs from the original Intel archive. Including
softset.exe ( !! thought it was gone for good. )
They mention a connector which is for the 386/PC piggyback
memory cards, Imeg (pcib1210), 2meg (pcib1220, and 4meg
(pcib1240).
The 386/AT was a bit different and did have a cable for
connection to expanded memory.
I'd kill for one of the PC piggyback cards. I like original machines
but I get great joy in pushing their parameters.
