The FX-603PX is an Android emulation of the legendary Casio FX-603P and its printer and tape accessory. This emulator is based on the GNU Open Source Emulator FX-603P by Martin Krischik, but specifically optimized for high definition Android displays. It emulates almost exactly the functionalities of the original calculator and can be used as a full-featured programmable scientific calculator.

The FX-603PX supports all arithmetic, trigonometric, logarithmic, hyperbolic, statistical functions and all alphanumeric display options of the original calculator and last not least the FX-603PX is fully programmable. You can write up to 20 programs, using 110 registers.

With the build in FA-6 cassette interface simulation you can save and load programs and data to your Android internal or external memory card for later use. Results can be printed out with the FP-10 thermal printer emulator and copied/pasted to other applications.

Nice! Got the original last month with the interface for tape and printer. All functional.

Nice little programmable

very nice, thank you

The FX-602P was enough to tempt me to the dark side.
So much cheaper and faster than the 41C.

Thanks ! Very nice. Works well and looks good !

A bit of a necro comment but the FX-603 Simulator had been updated this month.

The new version has a new file manager to support Googles stricter rules for file I/O. I tried to make a good user experience as was possible with new document management system adding import and export of your programs.

Note that the FX-603P has RSSAVE and RSLOAD which saves and loads plain text files. If you have larger programs you can type them in on a desktop computer and load that way.

I'm a CASIO fan, and of all CASIO's i have, i still love the FX-602P the most.
What a machine! In its aluminium cover glory, stylish as hell.
FX-603P i assume is equally good, or better, but the looks and feel isnt imho.

Correct. I have both and FX-602P and FX-603P. The FX-603P and it's a little larger. Still aluminium but with a black coat of paint which isn't good for readability.

However it has some cool functions. Hardware wise the FX-603P has an RS-232C interface build in. Add a RS-232C to USB interface and you can store your programs on your PC.

As for the Simulator: I'll suggest the FX-603P — it has fractions, base-n and can save and load applications as plain text files. There is a bug ( https://sourceforge.net/p/uiq3/bugs/27/ ) but now that I can upload to Google Play again I'll fix it soon.

Guys, stop, you're going to make me go look for an fx-602P or fx-603P on ebay. Big Grin

The FX-602P was my first fully programmable in 1981 and I still like it. Hardware wise is the fx-603p similar to the fx-880p line. (8-bit HD62002 @ 1.228 MHz)

I've been looking for a long time, and you'll be shocked when you see the prices; $200-$300 is typical, and even some non-working units exceed $200, though most of these are from Japan, where prices make EU's prices look economical.

As always, patience is the only solution...

Find an FX-602P and embrace the beauty of the best non-RPN calculator of its era.

I've got a book full of programs I wrote for it. Lots of trivial little things but some sophisticated things. IMO, the best I managed was a tic-tac-toe game when the user played the calculator. The program used an alpha-beta minimax search to determine its move. All within the limit of the available 512 program steps.

Me too. My 602P died many many years ago. Random screen corruption and loss/corruption of program memory. I had the thermal printer and cassette interface but tossed them at the same time. I kind of wished I'd kept them....

That's always the way.

I lost mine when moving home. Probably left them at my parents house and they did not know the value.

I have wondered about starting a collection for those old programs. Preferably with a source code repository. Since the FX-603P hast plain text import and export one can would not even need to type it all in.

Paul Dale · 01-08-2022, 10:40 AM

A repository for FX-602P programs would be good.

Do you have these programs still? That tic-tac game seems very cool!

Dave Britten · 01-08-2022, 02:04 PM

I'm big on software preservation, so of course I will say YES, archive it all!

Paul Dale · 01-09-2022, 12:36 AM

I should have it still but it's in storage since I'm moving house. I tossed a similar book for the HP 34C many years ago which I somewhat regret.

The FX-603P could hold 6,144 steps. Were individual programs limited to 512?

Not that I know. However, if you want backward compatibility for your saved files you need to keep it below 512.
