Hello!

Clive Sinclair is a true genius of an inventor. The T.A.Edison of the 1970ies and 80ies. And totally self-taught - he did not waste a single day studying at university. The ZX-81 which was my first home computer came with 1kB of RAM. And this included the video memory. There was even a chess program which fitted the remaining part of the the RAM. It did not play well at all, but it "knew" the rules.

An absolute must-have for DIYers is the Sinclair PDM35 multimeter, a by-product of his calculators. One should not work on a vintage calculator with any other than this multimeter :-)

PS: Sinclair now makes strange lookig electric bikes, but under a different trade name.

PPS: For DIYers there is an Arduino-based reproduction kit of the Sinclair Scientific: https://www.tindie.com/products/ArduinoE...-emulator/
Unfortunately it is out of stock right now, but maybe there will be another production run.
