back to article Happy 60th, Sinclair Radionics: We'll remember you for your revolutionary calculators and crap watches

It is 60 years since the founding of Sinclair Radionics, a forerunner of Sinclair Research and responsible for some nifty calculators and a not-so-nifty watch. The company was founded by Clive Sinclair, then a mere 20 years old, in July 1961. Its first product was the Sinclair Micro-amplifier for hi-fi systems, which was …

      Mine, sadly, has long gone. I remember a friend of mine buying one for thirty quid in about 1972, and saying "That's an amazing price - they won't go much cheaper than that." I bought one a year later, and the price had dropped to £18, and I remember thinking "Ha - that showed him. Thirty quid? But still, £18 is a fantastic price, they won't go much cheaper than that..."

      Of course, ten years later, 4-function calculators could be picked up for £1.99.

      My father actually adapted mine to allow you to plug in a cheap power-supply (sort of thing that was used for transistor radios). A mains-powered calculator!

      What amused me about the Sinclair Cambridge was what happened when you divided by zero. Error code? Ha! The display just rapidly ran through numbers until you pressed clear. I used to experiment by dividing by very small numbers - you could get different speeds of display changes...

    Sinclair actually launched two monochrome mini TVs, the MTV1 in 1977 was a miniaturised conventional CRT with cathode behind. The FTV1 (TV80) came along in 1983 and had an amazing CRT with a sideways electron gun, to a shrunken screen that was then made conventional format using a lens. It also used a flat pile battery from a polaroid camera. Sony and Panasonic also did a CRT pocket TV, but Casio came along with LCD and blew them all away.

        Technically it was the Science of Cambridge Mk14, that company being Sinclair's first bolt-hole from the NEB. It had the world's first membrane keyboard, which needed occasional dustings of talc to keep working, and an optional tape interface add-on that I never could get to work.

        Practical Computing ran my first-ever published article, on building one.

        I also recall the fun game of setting the Enterprise to divide by zero and watching it flatten its batteries as the LED display tracked in real-time its attempt to approximate to infinity.

    I've still got my Cambridge Scientific calculator. The power switch went a bit dodgy after only a couple of months, but it didn't deteriorate any more after that and the calculator is as good as it was in the 70s when I got it. Mine must have been a second version because my mate got one a few months before me and the numbers wore off the keys of his after a year or so, which has never happened to mine. I remember it being a battery hog and having to use alkaline batteries, which were quite expensive on paper-round money!

    Sinclair pocket calculator

    A friend in the 6th form had a Sinclair calculator. We were doing 'A'-level maths and he got it out to calculate the square root of 36 (which I knew to be 6). The Sinclair gave the answer 5.9999999999.

    1. Stumpy

      Re: Sinclair pocket calculator

      It's because the early calculators didn't actually have a square root function properly programmed either in their software or in the hardware. Instead they used Taylor Polynomials to approximate the answers so would always be slightly off when it came to rounding to a fixed number of decimals.

      If you're talking about the Sinclair Cambridge Scientific it only had an 8-digit display so you wouldn't have got that many '9's. A friend of mine had one, too, and my recollection (possibly clouded by time and beer) was that when you asked it to do something really esoteric like a square root or a trig function it only deigned to give you six digits.

      Still, even five nines was pretty good, back then! The HP35 would do better but cost and order of magnitude more (they were advertised in New Scientist, and I recall wanting one so very much ... but not at that price!)

      Rounding errors are far from new. If you use a book of four-figure log tables (such as Frank Castle's "Logarithmic and Other Tables for Schools") to multiply two by two, you will get the answer 3.999.

      I am always nervous about using log tables since I learned of the possibility of publishers inserting deliberate errors as canaries for plagiarism. What would happen if somebody designing a bridge inadvertently landed on such a deliberate error, and the bridge ended up collapsing?

      We have two at the museum - one "accessioned" as it was built in Merthyr so is sat on a pedestal with "do not touch" labels - the other bought from eBay a few years ago so that people could have a go.

      Mostly they enjoy it but steering is a bit odd, the brakes are really rubbish, the chain keeps falling off the idler, and in order to save on a differential just one rear wheel is driven by the pedals, with the other single wheel driven by the motor, so it's rather lopsided. Our eBay version doesn't have a battery any more, but the "go" button is "on/off" so I'd imagine it'd be quite difficult to control at first.

      The other big downside is that the seating position is not adjustable, so unless your legs are within a certain range of lengths you will either find your knees in your chin or be unable to reach the pedals.

      And it's always worth warning anyone wearing a skirt that it's not the most elegant of machines.

      If you're looking for something safer and more practical, there are several machines along the lines of the Renault Twizy, but they're not cheap - the C5, as well as being made on a spare production line in a washing machine factory, cost about the same to buy. My calculations suggest the entry model Twizy could buy you perhaps 40 reasonable-quality washing machines.

        That is because the voltage of a badly-designed power supply, especially one using an old-fashioned steel-cored transformer, and even more so one using a cheaply-made transformer, is very load-dependent; and without the leakage current flowing through the loudspeaker and its coupling capacitor, the voltage can rise above the PIV of the collector-base junction of one or the other output transistor and start it conducting when it should not be.

    These days one can use a handset to do what once required a desktop computer: mirror it to a TV, pair a Bluetooth keyboard and mouse, and you can do word processing or coding or watch movies in a hotel somewhere on I-40.

    The QL would have given us similar capability, at least similar for its time, back in the early 1980s, only it didn't catch on so the software and storage didn't develop.

Not even in the running. Add to that its shoddy manufacture, it's held together by string and chewing gum design (later revs were mostly fixed), and the total fantasy world Uncle Clive lived in and it was obvious to all involved the QL was a fiasco. At any given time about half the QL's in the office were inoperative and my abiding memory of the Sinclair QL is partly dissembled machines sitting on desks in various states of triage surgery.

      In 1984 the Macintosh was a game changer. The IBM PC/AT was a game changer. The QL was just the punchline to a joke. A bit like Lucas Electrical and the British car industry of the 1970's.

        Yeup, OPD was a QL with a phone stuck on the side. All the same problems as the QL but I seem to remember the cases were a bit more robust so less likely to fall apart. Still the same internals problem so I dont think I ever saw an OPD fully assembled except at demos.

        I think the word that best describes the QL was shoddy. Although by the time they did the final clearance sale what was coming out of the factory was actually pretty good quality. But by then it was far too late. The market moved very fast back then. What was wow in 1984 was a big yawn by 1986. I sat down with my first 128K Mac in Jan 1984 but by December 1986 I had a Mac II sitting on my desk driving two Sony monitors with 4 meg of RAM and two 20Meg HD's. And two years later the same set up was one quarter the price.

    At school in 1964 I helped the science teacher to build a stereo system around a BBC studio Tape Deck and a Sinclair set of apmlifier, preamp and speakers.

    The sound from the Sinclair kit was, for those days, astounding. The Rector suspected that we had spent well over our budget!

    When I got to Edinburgh in 1973 the first thing I bought was a Sinclair Cambridge calculator. They were so new that at examination time the Heriot Watt University Senate ruled that while Slide Rules were OK we could not use calculators in our exams as they would give their owners an unfair advantage. Only 2 out of 14 in the course owned a calculator.

    I had a Black Watch. Actually, I had several.

    It'd work fine for a few months, and then one day you push the button and it shows you the time is something like "47:89".

    Send it back to Sinclair, then a few weeks later another one arrives. It works fine, then one day... and so on.

    Think I got through three or four before i gave up and bought a Casio.

    I had a Cambridge Scientific, a Black Watch, a ZX81, and a QL. I learned to do complex maths on the Cambridge, to not rely on the Black Watch <LOL>, to code in BASIC, Assembler and eventually Z80 Machine Code on the ZX81, and did some 68000 assembler coding on the QL.

    Everything Sinclair made (with the possible exception of the Cambridge calculators) needed modification and upgrading. The ZX81 benefitted massively from a bigger heatsink and bolted down memory extensions. The QL benefitted from 3½" disk drives, more RAM, and a better keyboard. I never owned a Speccy but those friends that had them hated the keyboard and the constant crashing.
