Zen, a chess program by Eric van Riet Paap, playing the DOCCC 1988 on a 6502 instruction compatible Mitsubishi M50743 CMOS microcontroller with 4KB ROM and 128 Bytes RAM and programmable I/O-ports, running at 8 MHz. Despite zero points and last place in the tournament, Van Riet Paap proclaimed commercial ambitions with his entry, well suited for small dedicated travel chess computers. The Mephisto Mini, Fidelity Marauder and Tiny Chess were released by Hegener & Glaser in 1989, 1990 and 1991 respectively, with more variations to follow in subsequent years, also incorporating the M50747 chip with doubled memory size and astonishing 256 Bytes of RAM.
