Hi Folks:
I can almost guarantee you that this is the very same platform that the Science Fair Microcomputer Trainer used, which was a special version of the TMS1100 by Texas Instruments. This chip was used in a huge variety of toys in the 70s and 80s, such as the Speak and Spell. A nice writeup on the Microcomputer Trainer is here:

I used to own the Microcomputer Trainer, and still have the chip and the manual from it. I immediately recognized the design pattern: 20-button keyboard (16 hex and 4 other), a 7-segment LED, a 7-led register display, and a speaker. I would be so happy to know if the manual from the microcomputer trainer is applicable to this new kit from Gakken.
