Software was distributed for the TI-99/4A in generally three different media:
- Cartridges called by TI Solid State SoftwareTM Command Module
- Floppy disks
- Cassette tapes.
Some programs even required both a cartridge and a cassette tape or a cartridge with a floppy disk, as the cartridges for the TI-99/4A could not save information beyond what was already pre-programmed onto them.
