Vintage Pocket Calculator.

I came across my old Sinclair Cambridge while clearing out a cupboard and it still works (must dig out the manual set with all the programs).
It brought to mind a much simpler pocket calculator that I bought with pocket money.

Re: Vintage Pocket Calculator.

I bought the standard basic Sinclair Cambridge when it first came out. Cost me the best part of a weeks wages. I still remember pressing 2x2 and being fascinated that it came up with the right answer.
I still used my slide rule for a long time as I didn't know whether I could trust the calculators answers.
I like the Addiator on that link. I had a less "sophisticated" one of those that was only half the length.

Ah, the Sinclair Cambridge - I remember it well.  We bought one for each member of staff when they first came out.

Re: Vintage Pocket Calculator.

My first pocket calculator (excluding the Addiator and circular slide rule)  was this.
http://www.vintage-technology.info/pages/calculators/h/hof18f.htm
It was very basic and cost (if I recall correctly) £15 which was a lot of money in the mid-1970s. It lasted many years and I preferred using it to more advanced calculators because the keys had a nice positive click to them unlike more recent models which seem to be just sprung.

Mine first was a TI-30, remember buying it in 1976, what a breakthru that was.

Re: Vintage Pocket Calculator.

I have my old Dad's boxwood carpenter's folding ruler made by Rabone.

Still works, and none of those fancy metric markings on it either.

No, but I can tell you how to avoid needing one. Wink

Re: Vintage Pocket Calculator.



My first calculator was a Texas instruments one with red LED display - didn't get it till I finished my apprenticeship though  - so had plenty of practice with slide rules- good thing about slide rules though you had to learn to estimate the number before you calculated it as the slide rule did not give decimal places, just a number. Came in useful as I can still estimate pretty well now - often close enough for everyday purposes without getting my phone or calculator out.

 

I must admit when i used to travel a lot for business I had a Casio programmable calculator and all my standard most used stuff was in there,  only had to put the variables in - which was a good thing as jet lag can turn your brain to mush when it comes down to complicated stuff.

Re: Vintage Pocket Calculator.

I guess pocket calculators were still in common use when this topic was started Smiley

Re: Vintage Pocket Calculator.

Ah mine was an old Casio, can't remember how old I was, but not very - I remember getting it.

I even know where it is I think, in the drawer underneath my parents computer.

Now this post has intrigued me, I am tempted to get two AA batteries and see if it still works.

Will check this later today and post back, might be able to get a few screenshots too Tongue

Re: Vintage Pocket Calculator.

From what I recall most folks used them for simple arithmatic with little or no understanding of square roots, integars or summation. I certainly didn't, and for most they were just a 'must have' gadget of the day. The most complicated thing I every did on mine (yep, I had one of the early ones) was percentages!

Just had a count and realised I've got 18, of various ages.

Sinclair Cambridge Universal (non prog) in the centre.

All LCD or redIMG_4655.jpg LED, except for the Citizen 800D (bottom left) with large green LED.

The older I get, the earlier it gets late.
