I owned a Techtran dual-casette data drive around that time that was 
a type of replacement for a paper tape unit.  ISTR that it could 
transfer at the truly stunning speed of 2400 bps.

It could do record search, skipping, copying, etc. all under software 
control (special "escape" codes).  Sadly I no longer have the 
documentation for it.

Maybe Al has some information on these old units.
