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.

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

Sinclair Executive Memory

The Sinclair Executive Memory is a four-function calculator introduced by Sinclair Radionics in 1973. It uses eight red LED digit displays and is powered by four button cell batteries. The low power consumption required to run off such a small power source was obtained by pulsing the power supply to the electronics.
