Estes 1976 Catalog - Digitron Calculator
 
3 Attachment(s)
I was looking something up in the 1976 Estes catalog and saw the Digitron Calculator near the back, with an entire page dedicated to it. It was the only time it appeared. The brand Hanimex was in the catalog picture. My daughter recently needed a non-graphing calculator for a class, so I searched on Hanimex calculator on ebay and was surprised to find a working one complete with the slip case and box for a good price. Estes blacked out the model number, the actual calculator in the catalog is a Hanimex 2170. I think it is a great addition to the workbench so I may need to find another calculator for my daughter!

Looks like a typical mid-70's eight digit LED non-scientific calculator.
Almost exactly the same as the Unisonic 1548 calculator my family got in 1976.
That thing still works too, but has red LEDs instead of blue.

We got a TI-30 a couple of years after 76 that I still have and works that has a red LED display. This display looks blue in the photo but is green like the Estes Catalog pic. Going down the rabbithole of displays, I believe it is a vacuflorecent display. It is really nice to look at.

The Company my Father in law worked for used to give these calculators away as promo gifts.
He gave me some of these in the 1990's, but they had the batteries installed for at least 20 years what a mess.

There were at least two versions of the 1976 catalog: No.762 had the calculator, no. 761 had the Camroc and Cineroc on the last two pages.

I had to look at mine because I never remembered seeing the calculator; turns out I have No. 761. Ninfinger and Estes has No. 762.

Yeah, same here. My first Estes catalog was that 761 catalog and I did not remember the calculator either. Was gonna look up the 762 catalog and see if it was there but now I don’t need to. Thanks! :)

That is a good point, I have my original 1977 catalog but I am not certain about ‘76. I don’t recall the calculator. Still cool that it was even in one edition and obtainable.

The earliest Hanimex calculators were made in Britain by Emihus for the Australian Hanimex company. However, the bulk of them, including the Estes one, were made in Hong Kong. Hanimex was mostly noted for photography equipment.

I remember the day in 1973 I first saw a handheld calculator. One of the kids in my AP Physics class bought one and brought it to class. We spent the whole hour playing with it, and trying to confuse it, LOL. The unit was $300 but he paid an extra $100 to get the model with a Constant key, which would store the last number calculated.

It truly was a miracle right in our hands.

Interesting, especially the 2 different catalogs! My first calculator was a Corvus 312: https://americanhistory.si.edu/coll...ect/nmah_334516
