I'm relatively sure there is nothing significant in the floppies unit box 
other than the disk drives and power supply.  In the mid-80's I obtained an 
820-II motherboard, and simply soldered "D" connector pins onto a floppy drive 
ribon cable, to connect a pair of 8" floppies to the thing, making up 
my first CP/M computer system.   The 8" drives were cheap and common then,
but the ones in the Xerox box and the Xerox cable were not so common.

Both are possible.  If you obtain and attach 8" drives, I can send you a
bootable floppy, once I get my system up and running again.  If someone 
provides more info about 5.25" drives, maybe I'll be able to get them 
working on my 820-II.  Better yet, maybe someone knows of more modern 
storage alternatives that could be made to work with these.
