Re: Data Becker CBM-8000 hi-res graphics

Preliminary look at the ROM. At the start there is a giant jump table, so it looks like all the commands will be via SYS.so:
SYS to $9000, $9003, $9006 etc to see what happens. If you get syntax errors then you know there must be additional parameters IE: SYS $9000,X,Y etc
An interesting board for sure.

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.

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
