I think that he was referring to the "dual mode" drive, not the recording,
and to the issues involved in using a "1.2M" drive from a PC, lifted from
a 5170, with a 360K diskette, to try to read and write things such as
Apple2, TRS80 model 1, Kaypro2, etc.
We have a real problem with any carelessness in the terminology!
It's inaccurate as hell, but most people will understand what I MEAN if I
say "5150 360K drive" and "5170 1.2M drive" in such cases, and
"DD" and
"HD" for the recordings, although I have NEVER been happy with saying
"quad density" for 250K-dtr, 300TPM 96tpi! And I REFUSE to call the
double sided version of THAT "SUPER DENSITY"!
