Recently I added a Texas Instruments TI-99/4A to my
collection. Since
then I also bought one in a off white or beige case (I'm not sure what
you would call the color). Was the non-metal case version of the
TI-99/4A a later model? I also need to know if anyone has a schematic
for both of these models?
The silver and black model is the original one. The beige, all plastic
case is the later model. IIRC the later model has circuitry which prevents
it from running third party cartridges.
