Then there were some DC100 tapes in a huge heap of TU58 diagnostic tapes
for VAX-11/730 and VAX-11/750 that looked different.

They were marked "BI-SYNC TRAINING TAPE" and "ASYNC TRAINING TAPE
TAP-895-103-1.0 3.04"
BI-SYNC is an odd spelling, but I would guess it means "BISYNC", the ancient
communication protocol mostly used by IBM. With the hyphen it sounds like it's
related to BI, but I suspect that's a red herring.
