Photos: A dip into Bletchley's classic PC archive

The UK's cash-strapped National Museum of Computing is based at Bletchley Park, home of World War II code-breakers and the Colossus code-cracking supercomputer. One of the museum's exhibits displays the best of British personal computing through the ages. Here, silcon.com takes an exclusive look at some of the exhibits.

Research Machines RM 380Z

Dating from the late 1970s, the RM 380Z was an 8-bit microcomputer with 56KB of memory used predominantly in schools.

Peter Chilvers, volunteer at the National Museum of Computing, said: "They produced research equipment and as the microprocessor became available they designed their own computer and the RM 380Z is the product of that work. It is the only real British computer company to survive."
