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.

Thanks Noel. I suppose if it was done it was a hack/not official system.

There were third party cassette systems, typically using some kind of
digital cassette format, that you could hook up with a terminal. One
was made by Sykes that I played with once upon a time:

But not UNIBUS - it was just a standard serial port thing, not tied to
any particular computer system.
