Was there a UNIBUS storage system that used a cassette
player as the
storage device .., rigged to send receive signals via a serial card
connection.
Yes and no. There is the TA11 Magnetic Tape Cassette System, which used the
TU60 Dual DECasette Transport (I need to create a page for that in the
CHWiki), but it uses a special controller card, the TA11 Magnetic Tape
Cassette controller:

There is a small cheap tape system which used a stock serial interface to talk
to the computer, the TU58, but those used DECtpe-II cartridges, not standard
casettes.
