IIRC, it was "not quite" RS-232. But that wouldn't be a problem in using
the NEC, instead of the RS, as they are both made by Kyocera with similar

There USED TO BE a program for the NEC for using the first version of the
Tandy drive. There was also a program for PC to use it, but ISTR a
requirement of a tiny amount of circuitry to dela with different voltage

There also was a widely circulated multi-page discussion of the
interfacing issues, sufficient to write your own.

I don't recall ever seeing any provision for using the second version of
the Tandy drive with anything but the 100 series.

Unfortunately, the copy of the article and the software for the NEC that I
