Clive Sinclair formed Sinclair Radionics in 1961, having a good understanding of electronics and transistor manufacturing. Always the entrepreneur he bought a quantity of transistor test failures from Semiconductors Limited (Semics) of Swindon. As seems to be the norm in British semiconductor history, it was convoluted. Semics was actually Plessey who had licensed Micro Alloy Diffused Transistor technology from Philco in the US. Sinclair used the transistors in a very small pre-amplifier and sold both the amplifier and retested/re-badged transistors separately.
He must have done this again as ST140 and ST141 transistors were on the market, albeit probably in relatively small quantities again.
Above is an ST140 Sinclair transistor. There is also an original Philco MADT transistor. In the middle is a UK manufactured Texas Instruments transistor.
Texas Instruments opened a semiconductor plant in Bedford, UK to manufacture transistors, before moving onto standard logic during the 1960s. It eventually closed in 1994. Sinclair became a large customer for TI in the UK through its various Hi-Fi, micro TV and other products including for the supply of custom ICs. Unfortunately the supply of custom TI ICs was problematic and Sinclair went back to standard logic for the ZX80 home computer and Ferranti Uncommited Logic Arrays for the ZX81 and ZX Spectrum.
The ST140 is an npn, hfe49, vf=715mV, so silicon.

The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle". It was the culmination of Sir Clive Sinclair's long-running interest in electric vehicles. Although widely described as an "electric car", Sinclair characterised it as a "vehicle, not a car".
i thought i'd already posted this but it transpires it was a digi version elsewhere.

As viewed through the window of my 1980 Laurel. It's the third time in a fortnight I've seen this now, the first time wasn't sure if I was daydreaming...
Last time I saw one on the road was 1985/86, on a school trip to London.
What seemed like a long walk from Wick, through Papigoe and Staxigoe to Girnigoe...good Viking names and you'll find these wonderful ruins near the lighthouse at Noss Head!

Restored service station located in Norton, Ks. The man in the picture is the owner...he has restored and maintains both this station and the old Oldsmobile dealership next door. He also has a good sized collection of antique cars he keeps in the garage.
