A83: Re: Re: TI coding skillz


ah, finally an intelligent person :-)

look -> I've written a ROM tool program, but never finished it. I used it to
deassemble/view the ROM in a normal text editor with addressing and stuff.
You can find the prgm at http://home.concepts.nl/~dsfs98/stuff/log/tirom.exe
. I'll upload it asap. You can then convert a rom image to a .HEX file with
addressing and so forth. Use the pogrom like this: click on 'convert rom
image to HEX' and type some madly flippin' large number in the 'end convert
address', then switch the converter to the extended mode. Click go and do
what the program says.

It takes a while to convert a whole TI83 ROM image, thanks to my madly
programming skillz (not!).

This excerpt is taken from a piece of the TI83 ROM: (looks FAR better with a
fixed width font)

cool.

This is one demo example. The rest should be there, too. This worked for ROM
version 1.07 of a normal TI83. D/L the program and decide for yourself if
you can figure out this mystery. Personally I would rather have more RAM
available than TI's coding skillz on calc.

I hope this corrects the fact that one of you called me some sort of
dumba$$.
