HP calculator emulator ?

LechU

Can anybody try to emulate classic Hewlett-Packard calculators ?

C source can be found on internet - look for "nonpareil"

Here's a Javascript one I like:

If you do "view source" on the page, you can see the source code.

Hehe.. try Pi sin for a good laugh. Is the real calculator also as accurate? This is almost as useful as Microsoft BASIC's cdbl() function [noparse];)[/noparse]

In fact, the result is perfect.
Just keep in mind it operates in degrees, not radiants [noparse];)[/noparse]

DUH! *blush* I should have realized that before looking at the source code. :-P

I love HP calcs, for years I've been trying to build my own but without using their software. This time around I think I have done it. The functionality I mean. One of the most difficult parts is to build the machine. Just a board and a display is not enough. You need a case and a keyboard, a good keyboard. el-cheap-o replacements just are not HPs.
My newest does not use the propeller. It just does not lend itself efficently [noparse]:([/noparse]. I tried already [noparse]:)[/noparse] (look at the BCD math I wrote a while ago....).

btw: emulating the CPU is not that difficult. (See my BCD pkg for similarities).

I use a 48G and a 32Sii. I thought I lost my 32Sii once, went on ebay to find a replacement, and it was over a hundred bucks! Luckily, I found it before getting a replacement. I use the 48G more.

Before I started programming the Propeller, I stumbled across Ray's RPN calc and I used it all the time on my old pocketpc.
