R.I.P. Clive Sinclair

Of course, Busicom was the first programed microprocessor driven calculator, it wasn't the first calculator using calculator ICs. That is what Busicom was trying to compete with, when going to Intel in the first place.

Clive Sinclair died at 81 after a long illness (probably not Covid)


'course now he is touted as being "the inventor of the pocket calculator"
(as with all "FIRST"s, it leaves out a few predecessors,such as Busicom
(1971, whose contract with Intel led to the 4004), Kilby's 1967 "Cal Tech"
at TI, etc.)
I'm not sure, but the HP35 might even have preceded the Sinclair
calculator.
As with all "FIRST"s, an entry can be saved by redefining the field.
Sinclair's was probably the first one costing 5 pounds or less.
