He did describe some structures in it at the end, but it was just the raw formatted track
data that TRSDOS used. I have a PDF of it if you like.
I didn't know about the reference cards. Until recently discovering the Disc
Interfacing Guide a few years ago, I only knew of him from his TRS-80 assembly language
programming books.

Yes, "TRS-80 Disc Interfacing Guide" in
1978, however it was all
low-level. Nothing file or directory-based.
He published some other stuff, such as pocket reference cards, and I
thought that I remembered (unrefreshed dynamic wetware) something else
from him that talked about the structures.
THANK YOU! for providing the details on the interfacing guide; memory
wasn't working
