Vintage Texas Instruments TI-1250 Electronic Calculator Red LED Display.

Hoping some vintage calculator collector will add this to their collection.. A fully functional tI-1250.  Nearly 50 years old (released in 1975).

On/off switch works.. all other buttons work..  The "6" key works, but needs a firmer push than others..

Battery connector (9v) works...  Looks like this one accepts  a power adaptor (see last pic).

Great condition.  Will include 9v battery.

Happy calculating!
