TI-99/4A Cartridge Connection
Romox is producing the GamePort expansion module for the TI-99/4A. The module, which sells for $39.95, plugs into the computer's I/O port and accesses the 9900 CPU directly.
The GamePort is designed to circumvent the reported plan of Texas Instruments to modify its internal software to accept only cartridges programmed in TFs patented GROM format.
The GamePort module, which accepts both GROM and standard ROM cartridges, includes an 8K ROM, plus RAM memory.
