As I already have the data for most ROMs, it can verify against the library data and also list the opcodes on screen as it reads them. I am hoping to check all the RAM registers via the DATA line as well. As well as the sockets, there is also a connector for flying leads which can connect direct to the chip pins with suitable connectors - even on a prototype board. I just played around with a 67 CRC chip and fooled it into reading a card. The CRC did all the normal motor control etc when a dummy card was inserted, but the data actually came from a PIC processor and afterwards the program ran nicely too - interesting cheers Tony |
