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.

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!

Powertran

 

In 1979, the British magazine Wireless World published the technical details for a "Scientific Computer". Shortly afterward the British firm Powertran used this design for their implementation, which they called the PSI Comp 80. It was sold in the form of a kit of parts for a cased single-board home computer system. The system was based on a Z80 Microprocessor addressing a mixture of 8 KB of system RAM and EPROM, plus 2 KB of Video RAM. It used a National Semiconductor MM57109N as a mathematical co-processor to speed up calculations.
