Romox was a software company started in 1982. They produced several games for many different game machines,
and computer of the day, including for the TI-99/4A. Romox also created a device called
the Edge Connector Programmable Cartridge (ECPC) in 1983. The idea here was that Romox sold a programmable
cartridge which could be used over again to load games from the ECPC. The cartridge sold for $24.95 and
you could burn a game onto it using the ECPC for around $10. These systems were going to be setup in different
stores such as K-mart, Sears, and 7/11's. The system did take off for a while, but Romox went out of business
in 1985.. as did many vidogame companies during this time.
Romox did produce several games for the TI. Such titles as: Topper, Hen Pecked, Disk Fixer,
Princess & Frog, Rotor Raiders, Typo II, and Ant Eater where some of the more poplular.

Below you will find several pictures of a Romox Circuit board. These used 28 pin ROM's, and Bob Carmany
has several burned ROM's still available. The problem is finding the circuit boards. I have several pictures
below that show it is not a very complicated circuit board and might make another interesting group buy.
The above picture shows how to open a romox cartridge. They can be quite tough, and though I am only showing
one hand above (I had to hold the camera with my other hand :>), it usally takes both hands on each side to
"pop" the case open. It takes a bit of a feel, so be careful the first time you try this.
Below are the ROM's that Bob has available. For more information on ordering ROM's go

The large capacitor is a .1uf while the smaller is a 22pf. The two diodes are 1N914.

This picture shows both sides of the foil, with the yellow being the top of the
board, and blue being the foil on the bottom.

The above are pc card drawings of the romox card layouts redesigned to fit on a card that will fit
in a regular TI module case. The top drawing is the TOP and the bottom is the BOTTOM. Note that
the bottom drawing is mirrored.
