Re: TI-H:
What the phreak? I just had to but in at this....if you can change the
ROM...why not make the "Ultra Calculator." We have people making new
cases...you making new ROMs...hmmm...why not scrap the calc....steal the
LCD and other essencial parts, make a phat case, put a board in with a
new ROM, take the knolodge of the Z80 and the LCD and make the "Ultra
ROM," with GUI and all that we ever wanted but couldn't...It's a good
idea if you're willing to spen money on a case and other crap... Oh
yea...I would buy a metal case with metal buttons engraved with the
stuff...If I had the money...:)
