I thought I better check your calculations are correct - there are a few digits there that just look wrong.

Here is my Sinclair Scientific after calculating (1 + 0.06/360):



Now the rest of the calculation:



Before you get too tough on my Sinclair Scientific, when this came out, there was only the HP35 at 1/5th the cost of a new VW beetle and the HP45 was a bargain if you had just won the lottery.

The Sinclair was brilliant compared to a slide rule or log tables. And it was sold as a kit! You built it yourself, and when it didn't work, Clive would replace it with a  working one for a bit under 3 British Pounds.

Unfortunately for Sinclair, HP and TI started bringing out excellent programmable scientific calculators the next year that were more affordable then the HP35, making my Sinclair Scientific obsolete.

Clive Sinclair took an early 70's TI 9 digit calculator chip designed for x / + - fixed point calculations only and crammed a 5 digit resolution floating point RPN calculator in the same mask ROM space. Notice how there is no equal/enter key or decimal point key - who needs them anyway? Don't need exponentials either when you have a perfectly good log/antilog function.

Mostly my HP-28S and (when it is feeling in the mood) Casio FX-3600P.



Oh, and the one in my profile pic :D

Actually no, not that one, the CFX-200 in that condition is worth way too much to wear regularly. It only comes out for special geek occasions.

I wrote a blog article nearly a year ago on the subject of modern calculators and how useless they are. 12 months on and I still haven't bought a new one!  http://electronicsdesigner.blogspot.co.uk/2011/05/difficult-calculations.html

I took the photo for the Pistonheads forum. What can I say, it is all about cars. People often claim to have things that aren't actually theirs (to put it in context, there are people there who do own interesting metal like XJ220s, F40s, McLaren F1 etc) and someone calls for a Custard Test. Originally this involved getting a tin of Birds custard in the same shot as the car which the author claims to be theirs.

e.g. http://img444.imageshack.us/img444/1222/12072007080dr4.jpg

More recently they have had:
Jason Plato (British Touring Car Championship winner) http://images.pistonheads.com/nimg/23419/Plato%20custard_1-L.jpg
Chris Harris (journo and owner of a fleet of Porsches) http://thumbsnap.com/eJdsqIcS

Jason even got custard into a Porsche 911 review on Channel 5 TV. In my case, Custard Test was called, and that was the request. Yes of course it's childish. I'm too old to grow up now.
