I read this on the Heath listserver, and figured someone here would be
able to help him out :). Reply to him directly as I don't *think* he is
on this listserver.

Does anyone know or have a reference regarding the
layout of the HDOS (H8/H19) diskette and filesystem?
The generic HDOS documentation doesn't include it.

I'm looking mainly for the way that HDOS organizes
files on the diskette and the format of the
directory track.

I will be creating software that can add/remove
files from an image of an HDOS floppy.

This is in continuing development of the SVD
(www.rothfus.com/SVD). The SVD can now boot the H8
and will soon be tested on the H19 (thanks Jack!).
