Did you know Texas Instruments will still sell you a TI-83+ calculator, completely unchanged since April 1999? And it’s still $100!?
As of sometime early next year, the TI-83+ will have launched closer to the world’s first handheld calculator, Busicom HANDY-LE LE-120A (Feb 1971) than today.

First one is this #Busicom 811DB. Was sold as non working, but @tonyfishlock.bsky.social gave it a hard stare and ... voila! Lovely green display. Look at that label on the back 😊

Il a été conçu au départ dans le but de faire une calculatrice pour busicom. Le projet a capoté et a été transformé en cpu "généraliste"

Trying to find the oldest calculator I can find for a reasonable price on eBay to rock up with to my end of year maths exam.

Pencil sharpener and busicom are my top two.

TIL: i4004 마이크로프로세서는 Busicom 계산기용 칩을 개발하며 만들어졌습니다. 당시 Busicom사는 인텔에 계산기를 위한 12개의 칩셋 설계를 주문했으나 Ted Hoff가 이 설계가 너무 복잡하다며 대안으로 4004를 고안했습니다. 이후 인텔이 재정난을 겪은 Busicom으로부터 계산기 외의 용도에 대한 권리를 되찾아 오며 i4004 개발 비용 6만 달러를 환불해 주었습니다. 그리고 이는 오늘날 인텔 마이크로프로세서의 시발점이 됩니다.

So other than some dodgy #Atari disks, I also picked up a Dymo (had to dismantle & clean it), a rather cool pencil sharpener (dismantled and fixed by @tonyfishlock.bsky.social ), a #Casio databank (almost a calculator) and a beast of a Busicom #calculator I'm still trying to put a date to!🙂

Intel lands its first big contract in 1969—building custom memory chips for Busicom. That deal sets up the work that soon leads to the first microprocessor. #ITHistory

In 1971, a Japanese company named Busicom approached a young semiconductor firm called Intel, asking them to design a suite of custom chips for its line of electronic calculators. At the time, Intel was barely three years old and primarily known for producing memory chips. But one of its engineers, Marcian “Ted” Hoff, saw an opportunity to do something revolutionary.

It's funny, because transistors had an immediate impact in useful applications. Radios became much less bulky and cumbersome, even pocketable, and calculators could move from being chunky desk boxes to eventually being put into a watch body.
AI cannot claim to have had that watershed moment.

Supersized chip family gathers for the 54th anniversary of the Intel 4004 CPU — 4001 ROM, 4002 RAM, and 4003 shift registers feature in a reconstructed Busicom calculator build
Modern technology means the 130x scale discrete transistor 4004 CPU runs at twice the speed of the real thing.
