Re: TI-H: What's wrong with hw2?
hehe.. And how would they change the assembly syntax?
It isn't ti who made that up you know, it is how the cpu in it works, and that
is made by motorola and has been the same since 1984.
What has changed is certain things in the peripherial circuits in the ti89. The
chips that handle rom-protection and lcd updateing for example.
The big problem with grayscale is that in hw1 you could have the screen-ram at
any memoryposition (almost, a stepping by 8), but in hw2 you can only have it at
certain memorypositions. (I don't remember the exact ones now) and they have
also changed how the updateing of the screen works, makeing it quite a lot
slower.
Have you btw any idea at all how things like grayscale work on the calcs? Do you
even know how a microprocessorsystem like the ti89 works? It doesn't sound like
that on you guessings. Or maybe I just misunderstand what you are saying.
