That is an incredible collection! It looks as if it might be on display for the public to see as well. Wonder how many years it took to assemble and where he found some of those machines at.

"BIG Collection" indeed! And so well presented -- sure would be nice to see it in person.

I looked through the alphabetic-by-manufacturer page, and found at least one item I've got that he doesn't: a Litronix 2260 "exponential". (But he does have several close relatives.) I'm sure there are others, but I wonder how many?

That collection may not represent truly comprehensive coverage of the subject, but it's got to be at least representative of just about every facet one might be likely to consider. Wow!

(I'm going to show this to my wife -- maybe she'll get the idea that it could be a lot worse!)

And re: the "original TI" -- where's the display????

This looks like the demonstration calculator Jack Kilby et al at TI put together in the mid 1960's. It didn't have a display -- it printed on a thin strip of paper that exited on the left side of the machine. (It was a thermal printer. LED's weren't quite ready in 1965.) The design was produced in 1970 as the Canon Pocketronic.

The original "Cal Tech" prototype is in possesion of either TI or the Smithstonian, so I suspect this one is a replica.

If you are interested in TI's Cal-Tech Project you should read these two articles:

These fotos have been taken in the "Heinz Nixdorf Forum". That is a (real world)-museum for computer history, located in Paderborn, Germany.

You may visit this museum at http://www.hnf.de. There also is a VR-tour through the exhibition where you can see the "calculator-wall".

I never visited the exhibition, but since it is only 120 kilometers away from where I'm living I definitely should go there!!

Would be nice to touch these calculators or even better run them. :-)

There is a picture of the Cal Tech Prototype in the HNF forum and underneath this quote appears " As is illustrated by the display, products became both more widespread and more powerful. Hewlett Packard from the USA in particular, has dominated the market for high performance calculators, whereas companies from eastern Asia have been sucessful with low-cost mass products."

Such a shame that this is no longer true!

there is an even better photo of the cal tech on page 14 of the guy ball/bruce flamm book and i have wondered since i first saw it: since there is no "=" key but there is an "E" key, was the first t.i. an rpn? and if so; why did they dumb it down? i guess the "E" could be "equals". btw: they date it as 1967.
