Mr. Nagano, from Tokyo, Japan send me photos and circuit diagram of an AIM 65 reproduction he designed an build: the AIM65-CPLD-3v3.
It is a beautiful, functional, and aesthetically faithful clone. In fact, he built two, one with a CPLD 3V3 version and a 5V version with a 6532 RIOT.
The AIM65-CPLD-3v3 will become available as a complete system (sold on ebay) in the near future.
