Anybody know what these are for?

I have a pair of Pertec-branded circuit boards,
14" x 16"x, marked as follows:
I was told that they came from a tape drive.
They are primarily populated with 7400-series
TTL, with date codes around early 1976. Each
has a small daughterboard, 2.5" x 3", with
discrete components -- I would imagine these
would be the analog circuits for read/write.
Does anyone recognize what drive these boards
come from? I don't have any particular need
for them, so if anyone has a drive that could
use them, I'd be willing to part with them
