I am not quite sure if it will work or not, but in Europe TI is selling an upgraded ROM module that uses the second 128k of interleaved ram that the european TI-92s have built in. Unfortunatly, most(if not all) of the american TI-92s only have one 128k RAM chip built in. My idea was to see if I could address that second 128k of ram using a special fargo program after I installed the second ram chip. -James
