To help out John and Robert, two kids working on a computer program for kids at a youth center I promised to put this link on my site. It's a link on the history The History and Significance of Software. You can find it here. While I don't usually take requests for external links to this page, I understand that free pizza is involved this time, which is a good thing.

About this museum One of my stranger hobbies is collecting calculators. I especially like programmable calculators, and of those I love the ones made by Hewlett Packard the most. This hobby started somewhere in the late seventies. I was already very much interested in calculators (see below) when a friend of mine discovered that a local shop sold broken calculators for about $1.50 to $10. They would normally throw them away but if you asked nicely they would sell them cheaply. That's when it started. Those broken calculators were usually very easy to fix, a broken print-track, a loose battery contact, a broken on/off switch - those were usually the problems. Some 'broken' calculators simply had flat batteries! Later I was able to buy some of the calculators new, and sometimes people would donate me their old calculators. So if you want to see your old calculator on the web - I'm your man! :-) Today producing a four function calculator is apparently extremely easy, you can buy a standard calculator for about $1.50. I've got the feeling that more work was put in the older calculators resulting in better products and peripherals. Today's super programmable calculators may have a abundance of functions and options, but also quite often stupid bugs, interface problems and omissions. However, the product expected life-time of modern calculators is probably much shorter also. There are exceptions however. What do I collect? There are a lot of calculators in this world and I can't collect the all. Therefore I've tried to find a subset that suits me. Therefore I've decided that I collect calculators that can run on battery (or solar) power. I therefore do not collect mechanical or mains powered calculators. Except for some of the older HP's which are so extremely beautiful. So, I try to collect ALL HP calculators and any other battery or solar powered calculators I can find. Some remarks The very first calculator I have ever touched is still in my possession. My father bought it on one of his visits to the US of A when I was about ten years old. It is the Realtone Model 8414. The second calculator in my life is still used by my father! The first calculator I ever owned was given to me by a friend of my father, and is probably the one that started it all. It was the Triumph 81C and I re-found it only recently when cleaning out the attic. It doesn't work anymore but I put it on display in this on-line museum anyway. The first calculator I ever bought myself was the TI 30. That was when I was about 12 years old (1977). Well, actually that was the second one, I had bought a four-function model myself, and when I showed it to my father he said I should bring it back and get a "real" calculator. The calculator I bought had a "flaw" (√-9 = -3) which was enough to get my money back. He then tried to explain all the scientific functions to me but I didn't quite understand them! My most favourite calculator designs are the HP 15C, and the HP 41CX. The most usable programmable calculator in my opinion is the Casio fx-602p (I'm not including the basic programmable pocket-computers). The best modern calculator, I think, is the HP 49G. And my reward for the best school calculator goes (with much praise) to the Casio fx-82TL. My reward for the worst keyboard design goes to the TI 68. When I get a new calculator I first examine whether it's still fully operational. If necessary and possible I repair it. Then the calculator is thoroughly cleaned. Except for a few (two, so far) exceptions, all calculators in my collection are fully functional. The calculator's picture is taken by scanning the calculator using a desktop scanner. All pictures were scanned using the same scanner and resolution settings (safeguarding the picture's relative proportions). All calculator pictures were painstakingly retouched to remove dust spots and scratches and such. For those looking for manuals, I hardly have any, so please don't ask for copies. Today the best place to look for calculators are flea markets, and most of them sell their calculators without manuals and such. If you're looking for HP manuals, try http://hpmuseum.org (link valid 2006-10-29). Some Casio manuals can be found on this site: http://www.silrun.info (link valid 2006-10-29). Refer to Sharp's site http://www.sharpusa.com (link valid 2006-10-29) for some of its manuals, especially for their organisers. Please email me if you've got a calculator you are about to throw away. I'd be delighted to add it to my collection. Anyone donating a calculator will get their name referenced on the calculator's webpage. ©2009 Ernst Mulder
