This was the inspiration for my trip to Fife today - I was contacted by 2 Flickr members after i photographed this C5 last year, and I can now confirm that it is still there, although I still don't know who actually owns it.
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.
Born on this day 146 years ago, Upton Sinclair, American author, muckraker, and political activist.
Upton Beall Sinclair Jr. was born in Baltimore, Maryland on September 20, 1878 and died on November 25, 1968 at the age of 90. He wrote nearly 100 books and in 1943 he won the Pulitzer Prize for Fiction.
He is probably best known for his book The Jungle which exposed labor and sanitary conditions in the U.S. meatpacking industry. The consequent public uproar contributed to the passage of the 1906 Pure Food and Drug Act and the Meat Inspection Act.
"It is difficult to get a man to understand something, when his salary depends upon his not understanding it."

i thought i'd already posted this but it transpires it was a digi version elsewhere.

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.

Does anyone remember Sinclair Opalene oil?
