Computer Hobbyvereniging Eindhoven, CHE was a computer club, located in Eindhoven, the Netherlands.
Their biggest achievement was the CHE computer, an Apple II clone in a big PC like case.
To enhance this computer they designed and kitted a built-yourself ASCII keyboard: the TOuCHE, 1983.

On this page you will find the scanned description of TouCHE. Based upon a 6532, a 6502 and a 2716, with supporting IC’s HEF4515, a 74LS00, 74LS244 and a NE555 a nice example of the small footprint you could achieve with the 6532 RIOT.
