In 1981 and 1982 the magazine Elektor (Elektuur) published a small 6502 system. Small since it only contained a 6502, a 6532 RRIOT and a 2716 2K EPROM and some logic IC’s and powersupply, all on a small PCB.
Several applications around this baord were publsihed, like a DCF77 clock, a general purpose clock, and a darkroom computer. Also a talking clock baord, around the speech IC UAA1003 was published.
Recently I obtained a DCF77 talking clock system, and I took it apart and cleaned it up to experiment with the boards.
