Thanks for the posting. I have the 201, 201P and Pro FX1 with cards. All three not working but all are now. Love the card one and have new cards made for me by Menadue. Used to take it to work on the B787 for the fun of it. Wrote the following programs for the cards: Great Circle program, Intermediate latitude, fuel on board, conversions, Cold temperature altitude corrections, Wind chill, Lunar cycle moon phase, and others. Love the VFD display. Cheers, Geoff

Sounds interesting. Does Menadue have a website? can you post a link?

Let’s try again on the url. It seems you might have url turned off for your reply section. Here is the card guy Menadue: “youtu. be / 1NByD6thetA” Remove the spaces. Cheers, Geoff Just retired as an airline pilot (Jan 1/23) and my last flight was to Aukland from Vancouver and return. That was my first international flight in 1988. Love New Zealand.

This weird programming language is really interesting! Thanks for going into its details.

I remember encountering calculators with something like that "constant" feature and never quite getting how it worked. It's a natural thing you'd think of if you were trying to replace a slide rule, because "multiply many numbers by the same constant" is perhaps the most efficient calculation a slide rule can do. While the language bears some resemblance to FORTRAN, the real FORTRAN's great special sauce from the beginning was that it had algebraic expressions with order of operations and parentheses. Without that, I'm not sure it deserves the name.

Yeah if you have a table of numbers that you need to perform the same operation on the constant operation is useful. I guess would have been more common in the days before computer spreadsheets.

Hello. Where can I find the "program manual" in PDF?

I’m not sure actually. I haven’t been able to find it either.

Programmable calculators were useful that time. They (Casio) never brought out a new programmable model after the fx-5800P (2006). I have the scans of the original Japanese brochure for the 201P.

Yeah, there is also the fx-3650p II from around 2013 which seems to be available in a few places like Hong Kong and Japan. I managed to find one recently and will make a video about it at some point.

IMHO the hidden connection ready thing on the circuit board is preparation for any higher model with memory card reader / writer unit. Maybe. If I remember it right, the only difference between TI-58 and TI-59 was the memory card unit for programs store on a higher model.

Isn't it a connector for program cartridges, like on a TI-95?

True, it may have shared the same circuit board with the PRO fx-1, although the carder read on that was at the top of the device. If that is the case is it still odd they put an access panel in the body of the calculator. It is as if they planned for a future pluggable peripheral that was never released.

The edge connector on the FX202P has mainly address lines on it, I haven't looked at the FX201P yet but I suspect it is very similar. I have looked at the internal program representation of the FX201P by replacing the HD36106 memory ICs with a raspberry Pi Pico. That gives you flash storage in the RP2040 flash and a USB interface. 1 Pin 6 HD36106 (CLKB) 2 Pin 15 T5006P (DIN) 3 nc (connected to a signal on the FX-201P) 4 Pin 16 TC5006P (5V) 0V on calculator 5 Pin 8 HD36106 (0V) 6 Pin 4 TC5006P A1 7 Pin 6 TC5006P A4 8 A9 9 A8 10 A7 11 A6 12 A5 13 A2 14 A0 15 A3 16 nc 17 nc

I can't understand two lines in the last program. 1. 0 = 0 - IM x =. What does "x =" mean? 2. IF 0 = K0 3: 2: 3:. Why three labels after a simple IF, not two?

17 steps for this simple program??? On a typical RPN programmable like Electrónica MK-61, this will take: 00: 22 x^2 01: 040A09 4.9 04: 12 * 05: 50 STOP SIX STEPS... You can also add 06: 5100 GOTO 00 for an automatic return and it's still 8 steps...

Yeah, it is quite wasteful of space. They did move to more of an efficient keystroke programming model in the fx-501p/fx-502p

The PRO-101 does have over twice as many steps as the MK-61, though, and they are non-volatile. You could put the parameters in memories and leave the results there too and save some steps. The PRO-101 uses colons to separate statements, which does use a lot of steps up. I suspect that when they decided to go for the 'Fortran' language they had to put the colons in to help with problems like deciding what the '3' is in the following: ENT 1 : 2 : 3 as it could be either: ENT 1 : 2 : 3 = 1 or ENT 1 : 2 : 3 : 2 = 1 You need to check for either '=' or ':' to know what the statement is. the colon actually helps a bit there.

RPN was much better for such devices...

True, with a four register stack it would have been easier to use.
