Hi Ruud and Steve,
it doesn't look like the supersoft board.
It's only the 6545 with some ttl's to access bitmap graphics instead of the
prebuild chars and the 16kb ram board.
I read the eprom and disassembled it short in the monitor.
It runs at $9000 and has several jumps for a lot of graphics subroutines in
the first bytes.
I think at $9000 is the init routine.

Here are pics:

And the rom-extension: http://www.ceffy.de/cbm8000.bin

@Ruud: Please send me the disassembly to vossi@ceffy.de

Has anybody a 6502 disassembler for OSX ?
I tried DiStella - it works - but it's VCS2600 specific....

greets
