unebonnevie Posted March 15, 2015 Share Posted March 15, 2015 Hi, I would like to know the pitch of the 44-pin expansion port of the TI99/4A, so that I can buy a connector for it. I am looking to make a 32KB expansion board. Is that possible? I see people modding the TI99/4A to 32KB. Would like to see the schematic if anyone knows. Thanks!

+Ksarul Posted March 15, 2015 Share Posted March 15, 2015 The side port connector is a 44-pin connector with .100 inch (2.54mm) spacing. I have about 100 of them that I bought in bulk back in November for a project that I'm nearly ready to start work on. 1 Quote Link to comment Share on other sites More sharing options...
