%	Which revision of the board do you have?  I have examples of two
%here, revision F (0K ram, two serial ports) with a 74123 at K11, two copies
%of revision L (socketed for full ram, two serial ports, both
%non-functional), with a dip-package crystal oscillator 2.4576 MHZ, mfr Dale,
%XO-438.

It appears to be a REV C board.  It is socketed for full RAM plus it has
two serial ports, one which I have verified is functional.  The other one
is missing a 2.4576 MHz crystal (there are supposed to be two on this board).
I suspect the missing socketed chip is the 74123 since pins other than 7,8,
and 14 have traces running to them.

%	The ethernet software takes up 5 floppys, and SHOULD come with a
%separate manual.  (You NEED at least one copy of the manual.

Ugggh.  Well, I don't seem to have inherited the floppies or the manual.
However, right now, I mainly just want to check out the board and see
if it even works in the first place.  Is there a diagnostic floppy for
it?  Could I get someone to mail me the diagnostic via email or floppy?
Also, what is required to connect it to a 'thin' ethernet system?

%	Did you get more than one of the ethernet boards and/or the tape
%boards?

Nope.  However, I have a friend who might be able to 'find' some more
stuff.  I'll check into it.

I have a DOS-73 card complete with all manuals and software that I bought
some time ago.  I haven't used it that much lately.  What is the current
going price for the beast?  I might part with it for the right price...
