It seams like there are several different ROMs
available - or schould we call it different cards ?
I have at least one version with a ROM to suppurt
the Mumps system.

Like the original Softcard - a bit glue logic to
adapt the signaly and take over the whole system
(inhibit the 6502). There was also a 6809 Card
with seperate Memory, I just don't remember the
