Z80 TI-83 programming

does teh TI-83 use an interrupt system like a PC? also,where can i get all teh hex values for the assembly opcodes? i dont want to get a link cable and want to code directly on my calculator

    No, it doesn't use an interrupt system, just CALLs to the system and ROM page switching via ports if required. Look on for opcode hex values, they're there somewhere. I don't think you can code directly on your calc, but try writing a debugger for it (I'm already doing one).

    You can only type in the opcodes. It would be cool if you could type in asm, but I found learning some of the hex codes for some of the stuff is handy. I assemble my .z80 and look at the .obj file. I will have the lines of hex code. You need to know where to cut off some of the unwanted hex code in that .obj file. I'm only learning asm and I don't know all advanced stuff yet.



    Ps. Try the code if you like pulling your batteries out! Cool lines and all though.

    Make a new program called ASMPRO and put: (in the file)


    Then at the Home Screen type:


    And press enter.

    Have fun pulling out your batteries. :)

    Note: I can't be blamed for anything that you type into your calculator. I just put the above for a sample program of how to run a assembly program. I CAN NOT BE BLAMED FOR ANYTHING THAT THIS CODE MAY DO!!!! USE AT YOUR OWN RISK!!!! THIS WORKS ON MY TI-83+, IT HASN'T BEEN TESTED ON 83.

    Aww, I only have a TI-83 and its ASM capability doesn't work right. :-( My TI-86 is cool w/ASM, tho. To prevent crashes, put C9 at the end of your code entry and make sure the stack is balanced.
