The top two boards remind of somewhat of Multibus boards in early SGI
systems, though those two boards are clearly not Multibus. I'd imagine the
larger header connector on the processor board is the memory bus, which is
similar to what you see in older SGI and VAX systems. (Can anyone verify
if the 6821/6822 are some sort of bus interface chips?) My best guess
would be that they are from some sort of 68k workstation or system, but I
have no idea which. The date codes of the chips/boards might help you
narrow it down some.

The bottom board reminds me of boards I've seen from Tek and HP rack-mount
test gear. It looks like the EPROM and DRAM have been 'borrowed' from the
board though.
