Re: A89: Re: Re: TI-89 ROM
Yeah, I've been doing some reading on the 92+ module rom calls, I would bet
the Video Ram starts in the same place on the 92+ as on the 89. The Video
Ram starts at $4C00 on the 92+... Somebody should try to find out if this
works and then find the end by plugging in a value approx 2000 bytes away
and see if pixels show up there... Of course you'd have to find a way (maybe
by 92+ rom call) to clear the Video Memory... I can't remember the exact
call but I think its tios::Clr_Scr or something.. Somebody check it out...
