Apparently yours and mine interfaces are autostarting, changing vectors in 
the low 1K. If there is no "exit routine" included in the EPROM, it should 
be possible to write or load one that just restores all the vectors to 
default. I could dump the contents of my Dams interface for easier 
disassembly. I would bet the firmware in your cartridge is very much alike, 
except for all references to $Axxx are at $8xxx and of course some I/O 
addresses through which the cartridge communicates with the computer.

I'm not sure when I'll find time to look at this, but at least I should be 
able to dump (read) the VIC-20 EPROM tonight.

Best regards
