Radio Shack Pocket Chess Computer 1450. Endorsed by Gary Kasparov.
I like this one because it's really thin. The manual says the 3 AAA batteries should give us over 300 hours of play time. The program is capable of under promoting. It has a schematic diagram at the end of the manual. But the processor is only listed as "U1".
Even though the name Radio Shack is in it, it has a label saying: Custom manufactured in Hong Kong by Scisys for Radio Shack.
