Has anyone come across a spem internal memory expansion?
How was this implemented in the QL?
Was it one that simply plugged into the 8301 socket - with through
connector and wired to the 68008?
A Spanish customer has a dead QL with one in. I am trying to get better
info from him (8-)#
... I suspect the ROM additions are a red herring. Anyone a clue as to
what is there? An original Sinclair EPROM fudge?
