I currently have 59 TI-99/4a cartridges, and I only remember finding one
that I couldn't get to work. If you havn't, try cleaning the cartridge
contacts with alcohol and a cotton swab. The unit's cartridge port may need
cleaning as well.

I have an older black & silver 99/4a and have heard that some of the later
beige ones included some kind of lock-out by TI to prevent 3rd party
cartridges from working.
