This was the first calculator which I got after passing 10th grade (class) of my school back in 1993 and I was totally fascinated by it. It was the first calculator through which I was introduced to programming and now I am a programmer/software engineer. I wrote my first ever program on this calculator but I felt that it has very low space. However I enjoyed working and programming with this calculator very much. I still have it but sadly it is not in working condition anymore due to wear & tear in so mamy years.
Thanks for the great video. The old school calculators are still the best and remarkably well engineered given the hardware constraints of that time. About 6 years earlier than this Casio, Sharp introduced the EL-5100 on the market in 1979 with algebraic entry, the first calculator to offer algebraic entry with a dot matrix display. For that time the EL-5100 was quite advanced, but had fewer features than this later Casio FX-4000P. The EL-5100 was AER programmable and had 10 alphabetic memories. The early AER programming model is internally performed as something similar to keystrokes, supporting full algebraic expressions but also allowing some weird, but effective, shortcuts, e.g. expression can start with an operator which takes the last value as the first operand, there is also no need to use commas between expressions just a = will do to continue without printing the value. It's hard to find a usable EL-5100 these days because the early yellow/green LCD screens have darkened over time. The EL-5100S has a silver LCD screen but is from a later date.
That's interesting - i'll keep an eye out for one. Yeah it seems like it used a similar LCD to the Sharp PC-1211/TRS 80 PC-1 which are also difficult to find with a usable LCD.
I was fascinated to see the Casio 4000P. It still have the one I got years ago. It was my first more modern calculator. It's languages and that of the 7000G are very similar. The 7000G has to add some commands and gestures to cover graphics.
Nice video! I've had this calculator since the mid '80s and used it in this video, in case anyone's interested: "From the first BASIC to Casio fx-4000P calculator!" where I talk about the first BASIC (Dartmouth College) and port one of the students programs to the fx-4000P and compare it's performance to the Commodore 64. Some folks wanted to see more examples on the calculator itself, so I'll point them to your video here. Peace.
I really enjoyed this. I was given one if these by my father when I was in high school. I popped some new batteries in mine this evening. Still works fine!
I have one of these, bought it in 1985 to support my Comp Sci degree course. Only ever programmed it once, in 1986. I wrote a program to perform Gaussian elimination for a numethical methods course. Wrote it out on paper first.

I want a calculator that feels satisfying to press. The moment you put force, you dont have to worry if it registered or not. Not sure if you can relate or not.
A Swiss manufacturer has an HP42S clone better than the original calculator and it's featured on this channel. For the HP48/49/50 install Emu48 is an Android device.
I have a question. Could you help me, please? There is a programm which is wrote on a paper inside your video. My question is about a character in this programm. What is the touch on the fx4000P, to write the fourth caracter at the third line. This is the caracter just before "Goto 4" that I'm searching. I think that it is the touch which is the first column on the left on the fx4000p, and at the fifth line. Is it right, please?
It may be related to the right arrow symbol. There are a few different right arrow symbols on the fx-4000p. From memory I think the one you want is SHIFT 7. Let me know if this helps.
Yeah the metal face is shinier than the fx-4800p. It says Made in Japan, Casio Computer Ltd on the back but I guess there is a chance is a Chinese clone. I would probably need to take it apart to find out.
I had this fx4000p calculator in 1992. I started my first programming on it and now I am a programmer/software engineer.

I still remember the fascinating programming days I had with this amazing calculator. I can still write this language off my muscle memory.

Casio calculators from the mid 80s seem to be very reliable, it is rare to find ones that are not still working.
Hola valor de la calculadora FX 4000 p xfa i como puedo comprar
I have one of these, bought it in 1985 to support my Comp Sci degree course. Only ever programmed it once, in 1986. I wrote a program to perform Gaussian elimination for a numethical methods course. Wrote it out on paper first.
i got a radio shack ec 4020, which is a rebranded 4000p. such a cool calculaor, cant wait to try some programs with it.
6:15 Only true nerds immediately recognize 53280 (or D020 hex) as the Commodore 64 screen border color register.
For me, the deal is if the machine has a solver (for integration) or not... the first programmables machines didn't have one.

Yeah that's always going to be weakness of Casio devices.
Sadly no more prof look calculators from Casio. Also no more engineer calculators from HP.

I think the last engineer calculator is hp 35s... In Amazon ,sell it.

Yes that is correct.
@@CalculatorCulture Thanks!
i found one of this on our old house, how much do they usually sell this right now?
I saw one sell on ebay recently for around $70 USD.
N-Queen problem. Keep getting a syntax error at R➡️A[X] Any help would be appreciated.
It may be related to the right arrow symbol. There are a few different right arrow symbols on the fx-4000p. From memory I think the one you want is SHIFT 7. Let me know if this helps.
Hmm, that 3800P looks really weird... Is it a CASIO or something 3rd party rebranded ... thing.
Yeah the metal face is shinier than the fx-4800p. It says Made in Japan, Casio Computer Ltd on the back but I guess there is a chance is a Chinese clone. I would probably need to take it apart to find out.
