  • Introduction

    The TI-86 is the successor to the TI-85, gaining native assembly execution, a stylish casing, and more advanced options. It also has over 90kb of RAM to play with, really helping with the TI-85's limitation.

    Model Specifications

    Processor6 MHz Zilog Z80 Processor
    RAM Capacity98,224 bytes
    Screen Dimensions128wx64h pixels; 21wx8h characters

    Checking ROM Version

    If you would like to see which ROM chip your calculator came with, press the following key sequence:

    [MODE] [Alpha] [S]

    Warning!! By pressing [ENTER], you will erase your calculators memory, losing all data and 
    programs. Press any other key to exit safely back to the TI-OS (Operating System).

    There are several different ROM versions for the TI-86, below is a list of them:

    1.2, 1.3, 1.4, 1.5, 1.6

    Programming Languages

    The TI-86 supports TI-BASIC, though before execution, it compiles the code, and checks for errors, as long as the code has been edited. Otherwise it goes right into running the program. Assembly can be programmed with out the use of hacks, like on previous versions of calcultors. Execute an assembly program by using the asm( command from the catalog.

    Please note that while an assembly program is being executed, it has the potential to crash, and wipe everything off of 
    your calculator. Also, if you are not careful, when the assembly program crashes, it could be fatal for the calculator.
    Use extreme caution when programming in the assembly language.
