Oh, interesting! Yeah, I can read the pack back with PDP11GUI (another couple hours, ugh, but we’ll see what we see.) I’m thinking it would be handy to have a bit of standalone code that would just read through a pack and dump CRC-16 for each sector out the console for purposes like this. Then I could just blast over single sectors that don’t match. Maybe I’ll work on coding up that bit of MACRO while the longer complete dump is running… cheers, --FritzM.
