Looking for HDOS diskette layout

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. *************** Subject: Looking for HDOS diskette layout Date: Tue, 3 Feb 2004 10:45:01 -0700 From: "Eric J. Rothfus" <eric(a)ROTHFUS.COM> 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!). Thanks! Eric
