The Altos 3068 multi-user Super Micro Computer

The 3068 Altos was a system based on the Motorola 68020 processor. The machine ran Unix System V or the provided Pick-OS 2.15 operating system. The system supported up to 40 separate terminals. The machine had an intelligent 8086 based file processor subsystem with four separate DMA channels for fast file processing. The machine also had up to 4 8086-based serial communciations modules each with its own 128kB of RAM.

The Altos 3068 can be considered a super-microcomputer due to the fact it was designed to support many different users at the same time. It handled up to 40 different terminals at a fraction of the cost of a similarly performing superminicomputer or mainframe.
