Fascinating...thanks for sharing this!  So the tape drive was integrated
into the chassis hardware.  Now that's proprietary.

I don't even see evidence of a CRC or checksum in the documentation.  Do
you think that each record has one, and they just didn't document it?

Anyway, very interesting, nice work saving these!
