Sinclair Scientific calculator
Posted: Fri Jan 08, 2021 11:11 am
Having recently received a gift of a TI DataMath/Sinclair Scientific hardware emulator kit I built it yesterday (it's largely a SMD build).

It works nicely (you hold key 7 whilst powering-up for Sinclair Scientific mode). What prompted me to post is that the web site links to a fascinating short history plus reverse-engineering of the Sinclair Scientific by Ken Shirriff.

As well as technical details it also has a software emulator at the top which shows the opcodes being used during the internal calculations.
