The first few bytes are vectors to $B009 (start) and $B076 (restore), followed by $42 $30 $EA $EA $EA. To me it looks like a CBM80 signature partly padded out, like Commodore at an early stage had planned to autostart the IEEE-488 interface, but decided against it. For comparison, here is the EPROM dump from the Handic IEEE interface. It also maps to $B000, but starts at 45056. Only the first 2K are significant, the rest is garbage. http://www.cbm.sfks.se/files/ieeerom.bin Maybe someone finds it interesting to compare the VIC-1112 ROM dump to this other interface and see if they have anything in common. -- Anders Carlsson Message was sent through the cbm-hackers mailing list
