TI Editor/Assembler Fundamentals
Video (10:48)

In this episode, we kick off the first installment of a series about using assembly language on the TI-99/4A. We explore concepts of what assembly language is, numbering systems, addressing modes, and have a peek at moving data around with the operations MOV (move word) and LI (load immediate).

In this video, we cover the following:

  • Assembly language in general, its capabilities and difficulties
  • Using the E/A cartridge, floppy disks, and interface
  • Understanding numbering systems and ASCII characters
  • Looking at memory and storing things in it
  • Addressing modes
  • Example of moving data & displaying text
  • Assembling & running your program
