Small spreadsheet or RPN calculator?

Now that we have Catalina(thanks Ross) does anyone know of some small spreadsheet or RPN calculator with little dependencies that would work on the prop?

    I remember using sc, but I thought it was tedius putting in data with it's vi bindings. Not my idea of ease of use.
    Anyway, it would be a start, but first I would have to get curses to work, an before that have a terminal like a vt100 emulator. (which I think exists)

    What would be really neat is Spin In A Grid, kindof like Scheme In A Grid that your link lead me to. One could interpret spin each occupied cell. One could do realtime math based on external inputs. You could adjust your formulas on the fly. Maybe even have realtime outputs. I haven't tried it, but can you do this kind of stuff in ViewPort on the PC connected to a prop?

    Unfortunately, I don't have the knowledge or experience or resources to program this. Just envision it.

    PropSheet could be a killer app for the propeller.

    I'm dreaming about a simple OS for my PSB and would definitely like to have a calculator on it...

    I'm a big RPN fan too...· I've programmed·a calculator for my Watch and my PDA already...

    Check out this javascript HP-35 applet.· If you "View Source", you can see the code...

    Yep, just run the CP/M OS under ZiCog on the Prop and use MutlPlan or SuperCalc.

    Check the TriBlade, RamBlade, DracBlade threads for how to get the extra external RAM required on to the Prop.

    More seriously, if you search for "RPN calculator in C" on the net you will find many such examples which must be small enough to compile under Catalina and run from a Prop with no external RAM.

    For me, the past is not over yet.

    heater: Thanks for the tip. I will bug you for help to try that out when my ramblade comes in. Fortunately it is coming with CP/M on the SanDisk.

    rayman: I see your PSB is out. I may get one and play with it. An RPN calculater for it would be great! A suggestion for a PSBv2 would be one that is barely larger than the screen, no throughhole parts and everything just plug into flat DIP headers on an edge. Oh, and microSD also. I realize it would be more expensive to produce it and all of the adapters you need, but It would make a good PDA. Besides, who needs VGA when you have a touchscreen like that. RPN on a propPDA would be great. Don't forget to add a really tall stack the HP48SX if you write one.
