This reminds me (for no stringently particular reason) that I have an
interesting Anderson-Jacobsen ASR terminal that has a disk drive instead
of paper tape for storing the data stream.

This is only slightly more interesting than the TI Silent 700 Model 733's
I have that use digital cassette tapes.

I've actually played around with them quite a bit by way of a data
recovery job I did. Very neat machines. They store data in something
like 66 byte chunks. The tape drive actually advances in discrete steps
that you can observe. It writes start and end marks for each block, and
also has an ASCII search capability.
