RE: Postfix algebraic scientific calculators still in production
Years ago at the University, in addition to taking a typing proficiency test (35 words a minute for five minutes with five or fewer mistakes), you also had to take a 10key proficiency test on an adding machine.
Add up lots and lots of numbers. Had to be very quick as well.

RE: Postfix algebraic scientific calculators still in production
Both videos were amazing. I'm not sure I'd practice 9AM → 9PM as one of the girls interviewed discussed, but I'm glad somebody does!
I am wondering the actual age of the videos... somehow they seemed dated... 1990s, maybe? Are the squads of "calculator women" still found in Japanese businesses? How about the school competitions? You can buy some plastic, yet very nice studentgrade sorobans for only a couple of $ off eBay. I got one a while ago and quickly trained myself how to do the calculations. When I was practicing, I could go reasonably quickly (4 or 5 digit numbers, nothing really big), but nowhere near what even a Japanese 8 year old can do. I do think that, as with a slide rule, these manual tools demand that the brain work more actively throughout the calculation and this instills better, more fluid, numeracy, especially in young children. I really cringe to see young gradeschool kids moving to calculators as early as they typically do now (at least in the USA, where my experience lies). I'd rather some years be spent first on nonelectronic methods: pencil/paper, mental, soroban, slide rule, ruler & compass geometric constructs. Calculators are amazing, but understanding what is going on and why should come first.

I'm pretty sure this is a typo in your post: "The video explained that Kamimura was going 9 keystrokes a minute." I'm pretty sure that I could manage that speed with my toes.

RE: Postfix algebraic scientific calculators still in production
I got one of these Texet Albert² calculators:
It appears to be a TI34 clone, but with the keys shifted around (and some relabelled) and a generally cheaper feel with printing that feels like it will rub off after a while (but it was quite cheap!). Also, the shifted function key labels are quite hard to read due to the abominable colour scheme. (Speaking of colours, the rubbery case is available in red, blue or yellow, but when buying from eBay you get a random colour.) — Ian Abbott

Their calculators are made in China of course. They seem to be mostly sold in crates as class packs. They have some other scientific models that are obvious Casio clones. — Ian Abbott

I never seen this clone of the TI34 before. Disappointing to read that the quality is not good. I also don't like the dark colored text against the black background.
I think Texet is going for an Albert Einstein theme with their calculator names.
