Re: A85: TI-85 Routine pointers




I can not remember the exact address. but it is not hard to find. The
pointers are all listed in TI-RAM.TXT (as pointers), and they are placed
just after the text mem (i think). There are app. 8 pointers followed by a
byte (which is the ROM page used when calling the pointers. If you look at
the beginning of the ROM you will see that there are some function which
loads HL with the value of one of these pointers, and then makes a JP
(HL).

The only pointer which has been used is the first one which points to the
function which handles key presses.
