There were a number of third-party controllers for the Xerox 820-II made as
well, which used easier to find/cheaper components than Xerox supplied. This
arose because of the large number of 820-II boards on the surplus market
that needed the controller cards which weren't available. Some of these are
still available at reasonable cost or even as build-it-yourself.

For the 820-I and 820-II, there are also hard disk SASI adapter cards that
plug into the parallel port (Z80-PIO ports) allowing use of a SASI/SCSI
hard disk controller and appropriate hard drives - ST506, ESDI etc.
