We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Altos 986-40E

Altos Computer Systems was founded in 1977 by David G. Jackson. It was acquired by Acer in 1990.

Founded in 1977 by David G Jackson, Altos was one of the first producers of multiuser computers, and the company stayed true to that focus to 1990 when it was bought by Acer. Altos’s earliest models were based on the Z80 CPU and CP/M or its multiuser variant MP/M. Later, the company would focus primarily on UNIX-based systems. However, it also sold systems with MS-DOS or Pick.

By late 1981, Altos claimed to have installed 15,000 systems and was selling them at a rate of 1,000 a month.

The 580 and 586 lines were announced in January and July of 1982, respectively. The 580 was a Z80 system running CP/M or MP/M while the 586 was based on the 8086 CPU running Xenix/UNIX. Both systems are nearly identical in appearance as was the 986 model introduced in November 1983.

Base Configuration: 10MHz 8086 CPU, 1MB RAM, two Z80 coprocessors, hard disk drive, 10 serial ports, Xenix
