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!

Clive Sinclair introduces the first pocket calculator

 

Clive Sinclair is the first (August 1972) to bring a pocket calculator - the size of a package of cigarettes - based on the Texas Instruments GLS 1802, only the basic calculations were possible though. Pricing: expensive but lower than others: 79 UK pounds. Power consumption is compared to other calculators extremely low due to a smart power switching technique. The reason why this calculator has a small footprint.

(Texas Instruments brought out the types TI2500, 3000, 3500) but they were still very expensive. All basic functions ( + - / : *) and a percentage key were present. Numbers were displayed by a special kind of LED's, at the same time the reason for high battery consumption. Rechargeable batteries only existed in laboratories yet.
