I think I remember knowing it at one time, at least well enough to
fake it when I needed it once -- though whether that was through
reverse engineering the file format or looking at a co-worker's ISV
kit manual I can't recall.

Sydex has a shareware device driver that is supposed to let you use
HP150 stiffies directly on a PC-compatible. I tried it a few months
ago on a non-classic (hmm, 7 years to go) Toshiba notebook but it was
not able to read the lone 150-formatted stiffy I had handy. Whether
that is because of newfangled hardware, funky notebook hardware,
inability of the software to handle single-sided stiffies, or bad
vibes I don't know. I am able to read the disk in a 9114B on my
Portable Plus though.

Hmm, maybe I'll try DISKCOPY on it tonight and see if that gets me
another stiffy that the 9114B can read. Cheap thrills.
