Agreed, it brought all components needed for processing onto one die. The next logical step was to expand capabilities to do more than just math.

The Casio HS-8G? They were built to last, MADE IN JAPAN in the 1990s.

I think my mom has that one too. It's a pretty basic calculator.

I have a Casio scientific calculator that I bought around 1985 and still use every day. It uses a single AA battery that lasts 6-7 years, basically shelf life. 37 years old and still looks new and functions perfectly.

Every calculator I use on a regular basis is vintage, all with vfd displays. I regularilly use my early 70's vintage busicom exec da-80 on my desk at work. no batteries, needs to be plugged in, with individual vfd tubes for each display segment. picked it up at a thrift shop some 8yrs ago for $0.99 and tax, works like new does what i need and is a great conversation piece.

RC286 I use vintage calculators but not that old, I have several HP and Ti that I use from the early 1990's and late 1980's, but I do have older 1970's ones as well, but I don't use them because they eat batteries too fast :-). All of them are pocket scientific calculators though, no business or general use ones.

@@RC-nq7mg I don't think they had VFD displays then, but they may have used RCA Numitron DR2120 tubes back then. Those were 7 segment filament (dim light bulb). I used them in a product I designed in 1973.

@@paulmoffat9306 Busicom exec DA-80, looks like vfd to me. 1972, also have a LLOYD's acumatic 310 with vfd display, 1975, and texas instruments TI-1025 1977 with vfd display.

It excites and enthralls me. I'm an older fella with eyes wide open!

And after 20 years most industries (as we know them today) will come to an halt. Wait and watch.

Antes da década de 70 dizem que o homem já estava pisando na lua , saindo de lá e retornando em segurança para a terra, enquanto aqui estávamos engatinhando tentando aprimorar a calculadora.

I doubt anyone today knows what a NPN or PNP or CRT means lol...who is replacing yesterday tech?

Ahh, but you may be surprised. While technology in respect to transistors may have shrunk, the technology remains the same. If you're paying attention then you still understand the basics. Although, I am old an a former Nay ET. It wa my life for a period of time.

I just checked the datasheet reference for 2SC284, and it states germanium. Which would be right for an early cylindrical metal can Japanese transistor. And the 2SC prefix just means it's NPN.

No, originally 2SA and 2SB meant germanium PNP and 2SC/2SD were silicon. Something went awry later on, all 2SA were germanium PNP, but2SB coulxd be either, but always PNP. 2SC are always NPN silicon. Usually 2 s d is also NPN silicon, but I think they lost the plot somewhere, because some 2SDs are PNP, 2SC284 is silicon without doubt. 0.7v forward on the junctions. They are amazing in that they compare very well to modern bipolar units.@@michaelturner4457

In England i know from my mum she worked at marconi in the years before transistor radios came along we had built radar and radios they closed down in the 60s I know in the same time 1960s to 1960s we produced TVs echoe Tvs the Valve tube radio and tube before transistor radio in England we made AVOS Test meters and exported around the world englang exported its tools and engineering to india so in the 1950s Tv cameras used seticon tube a kind of LIGHT sensor In the old days TV cameras began using Electronics and Tubes if you ever get a chance to see documentry on the saticon manufactur Its amazing. in 1970s i remember calculators And Transistor radios I wanted to reply only because i wanted to say The people in charge let Other people view the manufacturing but thats only part of the story in every industry be it British motor bikes or tea cups British motor bikes I had a triumph bike But soon became interested in JAPANESE the little honda and the FS1E and suzuki soon we couldn't get enough JAPANESE stuff Same with TVs hitachi and sony trinitron in the UK we Bought more stuff made in Japan or china or Hong Kong! And our manufacturing Abilities Declined to a point We Need The stuff because they Invested in advanced Manufacturing Technologies untill today I have to say they are light years ahead in making stuff For some reason in the UK We stopped making stuff

It's called greed, and GREED is killing this country !

​@Malcolm Jacobs they don't care about America. They can make MORE money screwing America

Business, innovation, science are all people things, not country things. A person is hired at a US company from another country, invents something we say "invented in the US". Was it? As for manufacturing most mo-mos like to call it greed, but it's a little more complex. Suppose you just invented something here in the US that almost everyone in the world would love to buy. Now you need to build a factory and hire 30,000 workers. Investors are lining up to give you all the money you need. Where in the US do you build the factory and provide all those jobs. You live in Dallas. So the city of Dallas says "Hey you invented that here so you should build them here!". Cool. So you look for land. Hmmm, no big empty fields in Dallas. Or in the suburbs. You look further out. You find plenty of land but few potential workers. So you look in other states. Now Dallas and Texas is screaming you greedy SOB. Right now the unemployment rate is 3.4% in the US. Companies from China, Vietnam, Malaysia, Singapore, Philippines, India, Pakistan, Brazil and several dozen other countries contact you and show you they already have the factories setup for the most part and plenty of great workers ready to start. And the labor cost in their country means you make $20 profit instead of $1 profit if made in the US. That's normally where the "It's GREED" people stop thinking. You as the business owner do what with the profit? Mosty plow it back into the business. More R&D, improvements, new products. You can hire 20x more inventors with the $20 profit margin and hopefully create 20x more stuff "in the US". But suppose you're a made in the US kind of person so you build your factory, deal with labor shortages so production is lower than expected so you're barely breaking even. But the product is selling well. The rest of the world (including in the US) sees your product and their engineers say they can build a newer better version and manufacture it for 20x lower labor than you. When that hits the market with better features and a much lower price what happens to your sales? Won't be long before you've lost all the profit you've ever made and have to close the factory and layoff everyone. It's a people thing. A "Made in the USA" is not something Americans will pay a huge premium for. A business needs labor. The US right now has a shortage of labor. We are going balls to the wall. And many Americans are dead set against bringing in workers from other countries. And many potential workers can't pass a drug test. So yeah, they want the $30/hour job, but are too high to show up or do the work.

@@deadby15 If you think deeply there can be only one God, no more no less. However, God's names can be limitless, because of unlimited attributes. And God is a Person.

Dedication? Or fear of not producing?, and being taken behind the lab and flogged at that time.

That's dumb, they could have built a double room, one cooled, the other where the calculators were and used gloves in walls like they do in bio-hazard laboratory's.

The heart problems could also have been due to overwork, so, going to and fro between very hot and cold must have contributed to the symptoms manifesting themselves. I don't know if overwork was an issue back then.

Couldn't have been green LEDs back then. Most likely green/blue phosphor flourescent display. I had several myself with that sort of display.

I still wear my 90's G-Shock. Works flawlessly.

The UK has high-speed rail, too, though not everywhere. Coal- and steam-powered locomotives are a thing in the UK, and can provide backup during extreme weather, when electric trains are unable to function.

The Casio calculator which you buy today won't last five to six years. Planned obsolecence? The HL-815 calculator I bought in 2016 failed within 3 years (made in Philippines).

My 1st calculator in high school in 1974 was the HP-21, which fit in a shirt pocket ($125). The nerds in school carried their calculators in a zip-pouch that hung from their pants belt. One internal rivalry between nerds was over the ownership of HP vs. TI . The super-nerds had the expensive programmable models. I still have my HP-21, but a roommate fried it by improperly unplugging it from the AC power. The stack memory paradigm in the HP's was sort of off-putting to the average non-computer-geek, but it had it's advantages.

I used an HP21 in college and still do to this day. There are so many advantages to the RPN logic and stack. I used to carry it using the belt loop as did many where I went to school.

I used a Ti 'Programmer' which among many other functions converted between binary/decimal/octal/hexadecimal. What a great tool when programming.

Hell, I can buy a calculator for 50p

do you have a website or something where I could see your collection..?

I've been VERY slowly working toward updating my ANCIENT site to have exactly that, but sadly, no, I don't have an actual page up. What I do have though is a browsable directory, with a number of pictures. richfiles.solarbotics.net/calc/

I also have most of my pocket/handheld models packed up. Another project of mine will be to get those photographed and on display as well.

That's an awesome collection.. Mr.

I can help you rebuild your website....

I used a slide rule, some kids used calculators, whose batteries died during exams. I never had that problem.

I still have and can use a slide rule. Sometimes I pull it out at work, just to get a reaction.
