Vintage Radio Shack 60-2441 Mega 2050X Sensory Chess Computer 64 Levels +Manual

Description

Works when used with plug (Sears brand not original I don’t believe)
I had batteries in it and it was on and then would turn off. It is possible my batteries are old. There also appears to be a spring included in the extra baggie, maybe for the battery compartment? Not sure but it does work fine with just the AC adapter plug! Includes extra chess pieces (not from this set)
