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,
