Vintage Texas Instruments "Speak & Math" Electronic Learning Aid, Circa 1980

Description

In good working order. These machines have an inherent glitch which can be fixed by pulling a battery out and installing it or unplugging the AC adapter and inserting again. There are videos online that show how to fix it. The case is in excellent condition but the battery cover is missing. The batteries stay in there very well though. Batteries not included but the AC adapter is.
