[sebhc] Forth disk

Great - I've got two H89's up now, running HDOS 3.02, so I've got to get
that sorted out a little bit and get some disk images in the archives. I
still don't have an org-0 H8 working, but I wanted to see the "new" DOS
so I just skipped ahead a little. I think these should work fine with
your Forth kit as while as the file uploader.

Someday soon I'm going to put you in the way-back machine and start
digging into the SIM-8 and MDS systems - I'm picking up an ASR-33 on the
way to VCF-East so I'll be in the right mode by the end of July.
