Summary
| Description |
Sinclair Executive calculator. Clever design of its electronics to reduce the power consumption allowed the use of button cells for the first time in a hand-held calculator, and gave a very thin design which was remarkable for the time. Photograph taken by myself of a calculator in my collection. |
