Speaking of the Xerox 820 ... I've got a little daughterboard that was made by
a local company, the purpose of which was to introduce a 179x where the 1771
lives. With the addition of some software I don't have, it makes the thing
double-density (MFM) capable. It even has a wire with an "EZ-Hook" for
attaching to a parallel port bit, though I don't know which one. <sigh>
With less than a week's effort, I could find this thing, but it would take a
concentrated effort of a month or so to find the one-sheet document that went
with it.

I have an 820 I'll let go reasonably. Shipping
will be a bit of a PITA.
Where are you located?

BTW, I am interested in either a z80 big board or a xerox 820 if
anyone has one they want to find a new home for...
