A86: Re: new news to some old news to others
it is not possible to overwrite the OS. i think you could disable it
though. you could set im 2, write your own interrupt routine that does not
jump to the ROM and you'd be all set. you would have only 128KB however at
your disposal. it doesn't really make sense because then you can't use it
as a calculator anymore (that is what a TI-86 is, isn't it :)

|every rom call that you guys are finding are the same rom calls that the
|programmers of the ti-86 used to program the ti-86
|
|all of these roms mimic the commands that are already on the calculator,
well
|i believe that they are one in the same. for example, someone found a rom
|call that does the same thing as >frac which is true in the sense that it's
|the same rom call that the programmers used.
|
|one thing i would love to know is if there is a way to remove the original
|programming of the ti-86 and overwrite it with a completely new os, change
the
|ti-86 completely, since what we all use is an os in the first place. the
only
|way i could see that you can't take it off is if the os is written in rom
and
|protected (which is probably true).
|
|but the question remains, did ti use all of the rom calls, or just the ones
|that it wanted to for the 86.
