EL9900G Programming

[joluc]

Hello dear Community!

I'm programming since a few years on a SHARP EL-9900G.
I have a lot questions about it.
What processor does it have?

What programming language is it?
(Everybody says it is TI-Basic,
but it seems more familiar to qbasic)

How to update the ROM?

I hope there's a lot of another "Programmers" out there.

Best regards,
joluc

As long as you cannot program it in machine language this doesn't matter too much.

It's the Sharp EL9900G programming language, what else? Calculators typically do not use any of the common programming languages but feature their own unique language. Earlier machines (think of the PC-12xx series) used to implement some form of BASIC. Programs can even be shared across manufacturer boundaries if the more or less subtle differences are taken into account (see my BASIC Comparison Sheet).

With the advent of graphing calculators the programming languages have moved away from BASIC (no more line numbers, different keywords and control structures), and from each other as well.

I don't know if the device is flashable at all. The link you posted is an old thread of mine asking the same question.

The board is OK, the sub forum probably not. I've asked the moderators to move the thread to the "Off Topic" area. I hope you don't mind.

You might want to look through the archives of MoHPC: try this one.

The Sharp(s) use a tokenized version of BASIC similar to TI BASIC, but with some differences. The ROM image may be upgraded, but you have to have the image, and you need to have the cable (sorry, can't help you with either one).

The cool thing about the sharp is its LCD display... its one of the clearest ever. My EL9200C was one of my favorite calculators, until it stopped booting up this past month (I think it has a bad cap, but that's another story).

The machine is a fairly slow calculator, but its programs run 'fast' relatively. Its fun to play with, but its no HP/ no fully merged fully integrated keystroke programming!

Good luck.
