You have an 820-II; the original 820 only has two ROMs (U63, U64).

I have a Xerox 820. I don't know how to tell if it is a -II or not. It is
marked as U05-013264

I think I have a “Big Board” that’s suffered a similar fate. Though it could

someone should check if it has 5 or 8" floppies or a hard disk
With permission, I’m forwarding this email about a Xerox 820-II that’s
available in Regina, Saskatchewan, Canada. (I live in Regina, and know Steven.)
Feel free to contact him directly. He’s also available by IRC; email me
