I confess my absolute inutility in these matters, but never is too late to
begin
the training. Do you mean one complete male D connector or D-Sub ?
There is some order in the soldering of the pins ?

I have three or four shugart 8" units but never tried to put them to work.
Mostly
cause of the fault of one power supply. If someone knows of the specs
of one Power supply for these floppy units, I should agree to get it.

Mmm... I should like to know if one 5'25 unit like the used for the PS/2
(with 37 pin)
could work connected to one Xerox 820. It was one 360k unit, I think. And I
have
one.

Another option, if there is no cabling problem, would be to use a couple of
IBM PC 5.25 floppy units, arranging one ribbon floppy cable in the same that
you
used with the 8" inch. I suppose would be easy to use one program to copy
the "standard" CP/M image available in some websites (prepared for the Xerox
820)
to 5.25 floppies.

Thanks and Greetings
