Hi folks,

Been rummaging in the garage for stuff I'll be exhibiting in the UK in July
and found this:

It's a 4-slot cage containing:

M7270 11/03 CPU
M7944 4K RAM (x2)
M8027 LP11

There's a fault label on the M8027 saying it occasionally drops characters.
Question is, anyone know what it was out of?
