Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

No 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!

Or come and get involved on our social media channels ...

Thank you.

Introduction of DEC PDP-9 18-bits minicomputer

Introduced in 1966, the PDP-9 was a 18 bit minicomputer built by Digital (DEC). The machine was a successor to the PDP-7 minicomputer, which it was upwardly compatible with and had roughly double the performance of the earlier machine. The machine could address up to 32KW of core memory.

The PDP-9 was one of the first small/medium sized computers to feature a keyboard/monitor system (a rudimentary for of operating system) which ran on the DECtape storage system.
