Joe, it is a Z-80 based CP/M machine w/ 64k RAM. On power up, you are
presented with the choice of entering the monitor utility, using it like
a typewriter - assumes printer attached, or booting up on CP/M-2.2.

Probably the main drawback of the 820 vice the 820-II is that it only
handles SSSD drives. In the 5.25" models, that is about 90k of storage.
