Check the listing for details. Texas Instruments Dataman works vintage 1970s. Condition: Used. Listed at 10.00 USD. I have for sale a used Texas Instruments Dataman from the 1970s. Educational toy. Do math. Guessing game for numbers. I'm not sure what all it does as I have no booklet for it. It has a new 9volt battery installed. Minus a couple of games worth of number guessing.
