The 4-Bit Microcomputer Kit from Gakken features a 20-key keypad, a 7-segment LED, and 7 individual LEDs. It comes pre-programmed with 7 different applications, and you can even program your own via the keypad. It’s a fun retro kit, just begging to be hacked! Don’t forget to check out Gakken magazine 4-bit computer rollout party in Tokyo.

  1. 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.

The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .
