How about making a springboard for a graphing calculator such as the Texas Instruments 86 or 89?

Ummmm, at the risk of asking a stupid question, couldn't this be done in software? Why bother with a SpringBoard?

I've been using Palm's a long time, and my kids wanted a TI tyoe graphing calculator, but none appeared (there are graphing programs, but none with a TI type calculator interface). Maybe there is a hardware issue that Springboard could help.

One thing about having it in hardware is it could use a better processer, if needed. I don't know about what the bus width of the Visor chip is, but my HP48Gx has a 64 bit processor, and is extremely accurate.

Someone posted this in another thread, but there is graphing software at www.hexdump.com

I haven't tried it personally, but it does graph.

I have been looking all over the net for graphing calculator functionality, but I have yet to find it. The HGraph program at hexdump.com just graphs equations. It does not allow you to find intersection points or do any other graphing related functions. Their are some good calculators, but none as good as the TI calculators, especially the TI-89. APCalc is my favorite, but if you need to use complex numbers, CplxCalc is the best. It seems to me like it shouldn't be too hard to port it to the Palm Pilot and it seems like somwthing you could make money doing, but apparently TI hasn't thought of this yet. Maybe if we approach them with the idea, it might make TI start thinking about it.
Thank You,

I would suggest going to http://icarus.ticalc.org/ and suggesting to them that they make a TI emulator for the Palm OS. Icarus makes many TI programs, and have even got the GameBoy Color to show 2000+ colors on the screen at once!

The HP does *not* have a 64 bit processor. No calulator does.

The HP 48G/GX (along with pretty much everything since the HP71-B) uses a Saturn processor, it's a 4 bit CPU specially designed by HP. It runs at slightly under 4Mhz and is made by NEC Corp, Japan.

Your HP's precision comes from the way it implements the functions to do the calulations, that's all. It will be easily doable in the Visor - in fact, there exist source code in C to perform calculations with ARBITARY precison. As with most things - it will come down to balancing precision and speed.

Well TI finnaly emailed me back and said that they are not going to make a emulated version but i bet some hacker might just take all the data off and convert it someday... Sorry for the bad news
