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 >>>

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

CP/M (Control Program for Microcomputers) is an operating system originally created for Intel 8080/85 based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations, and were migrated to 16-bit processors.

The combination of CP/M and S-100 bus computers patterned on the MITS Altair was an early "industry standard" for microcomputers, and this computer platform was widely used in business through the late 1970s and into the mid-1980s. By greatly reducing the amount of programming required to install an application on a new manufacturer's computer, CP/M increased the market size for both hardware and software
