I should mention that for anyone interested, it is currently available
at "ardiehl.de".  Alas, the published email address on the site is no-
longer valid.

After seeing what little there is on the Davidge machines (only photos
and ROM images on bitsavers and only a couple of videos on YouTube of
the "1538A.BIN" ROM image being executed under MAME), I think I may have
the most complete, working Davidge DSB-4/6 in the world right now,
so I'm hoping to put things together to preserve the knowledge.

(There's a LOT of similarity between the DSB-4/6 implementation and the
CCS 2422/2810 FDC/CPU combination.  Even the floppy formats are the
same although for 3.5/5.25 DD, I'm using all 80-track hardware rather
than 35 or 40 tracks.)
