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.

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.

And of course some were built right into the terminal; the TI Silent 733 comes to mind.
That was around 1974. My guess is that it was intended to replace paper tape that was a
popular terminal capability at the time (on the Teletype 33 and 35). Those things
actually had an API of sorts; I remember playing with it a bit but it was never
interesting enough to do serious work. The fact that it was limited (by the comm line) to
30 cps was not a whole lot of motivation.

CAPS-11 was the OS for this IIRC.
