The Xerox 820-II (eight - twenty Roman numeral 2) is a powerful 64k CP/M machine.
At a time when the Mac had received numberous awards for the inovative design of having the CPU inside the monitor, this machine had already slipped by the acadamy (along with commodore's original PET).
The entire computer is in the monitor sans the i/o devices -- disk drives, keyboard, etc.
Upon first powering up the 820, this screen appears.
You have a choice of loading CP/M, booting a dumb terminal, or booting a text editor.
The 5.25 inch dual floppy came standard with this machine.
This drive, however is the beefed up 8 inch floppy that handles formats up to 964k! -- quite respectible for it's time.
Here is the modem I use with this machine a USRobotics Sportster 2400 -- not much has changed over the years, at least not as far as the case goes.
This is where it all plugs in -- right into back of the monitor!
Here we have a shot of the manual, it is nice to have information...
