820
1 In Collection
The Xerox 820, introduced in 1981, was Xerox's entry into the personal computer market, built around the CP/M operating system—a widely used OS at the time for business and professional applications. The system was powered by a Zilog Z80A processor running at 2.5 MHz and came with 64 KB of RAM, a common configuration for CP/M machines.
The Xerox 820 featured a monochrome 12-inch monitor and an integrated keyboard housed in a durable, utilitarian design. Storage was provided via external 5.25-inch floppy disk drives, typically one or two units depending on the model configuration. It supported common business software of the time, including WordStar, dBase II, and SuperCalc, making it suitable for word processing, spreadsheets, and database management.
The system was marketed primarily to small businesses and professional users who needed a reliable and compatible platform for office tasks. It also had a serial and parallel port for peripheral connections such as printers and modems.
Though it did not achieve the popularity of IBM’s PC line, the Xerox 820 played a role in the early personal computing era, especially among CP/M users. Its design reflected Xerox’s emphasis on professional computing environments and served as a bridge between mainframe systems and desktop productivity.
