"8-track" data tapes, was Re: Compucolor items on eBay

The 8-Track Wang cartridges were not used (to my knowledge) on computers,
but on
the Wang 380 Programmer for the Wang 300-Series electronic calculators.

The 380 was a keyboard which plugged into a Wang 300-series electronics
package that provided a means by which programs could be recorded step at a
time
onto the 8-Track tape cartridge. Then, the programs could be played back.
The drive was incremental, meaning that it'd advance a little bit for each
step of
the program. As I recall, the advance mechanism wasn't a motor, but rather
a solenoid
activated ratchet mechanism that could step the tape along a bit at a time.
I believe that the drive could step both forward and backward, allowing
looping to occur (albeit rather slowly).

A few folks that I've been in contact with have managed to find Wang 380's
(Alas, I don't
have one yet), and have not been able to find the correct cartridges, but
have found that
taking old music 8-Track cartridges and cutting down the length of the tape
(a long tape won't
advance properly) will work as a suitable replacement.
