This is the last tape I have. It is labeled: Processor Technology; DEBUG, Advanced 8080 Debugger; P/N 727132 It contains: DBG8 0E00 11D4 DBG16 2E00 11D4 DBG32 6E00 11D4 DBG48 AE00 11D4 DBG64 EE00 11D4 END CC00 0000 I never used it because I don't think I had the docs and I never had a problem sticky enough to need it. One of the versions on the tape was never able to load but I was able to create it by comparing the differences between two others and making the necessary changes to create the bad one.
