Sharp's OA-310, launched in 1986, was a UNIX-based office computer that offered true distributed processing with multiple 32-bit CPUs. The OA-310 ran OA/UX-II, an operating system that added electronic data processing (EDP) functions and virtual memory management functions to the basic UNIX System V (release 2.0) operating system. The Ethernet-compatible LAN made it easy to connect multiple consumer-grade OA-80 processor models to construct a horizontally distributed system with file transfers and remote file access. The OA-310 could be configured with up to four 32-bit MC68010 or MC68020 processors. Dedicated controllers were provided for each I/O device — such as display terminals, disks, communication devices, etc. — to enable parallel I/O operations.
