The Xerox 8/16 was the successor to the Xerox 820 series. It has two CPUs: an 8-bit Z80 for running CP/M and an 8086 for MS DOS or CP/M-86. The power supply, display, and disc system were shared between the two processors which were otherwise independent. This computer was one of the first desktop computers to feature concurrent processing; a task could be started on one operating system and, with a special keyboard command, the user could switch to the other processor to perform another. Both processors could work at full speed as they shared no RAM or system resources. Only the input/output devices were locked to the user's active processor.

Our Xerox 8/16 is pictured here with the 5.25-inch floppy drive and hard drive unit.
