Mike, (M6800 Chess)
an early microprocessor chess program, written by Mike Johnson in Assembly to ran on a home built Motorola 6800 8-bit system at 1 MHz, with 16 KiB of memory and the program loaded by cassette recorder [1], searching about 300 nodes per second [2].

Achievements

Mike surprised by winning the First PCW Microcomputer Chess Championship, London, September 1978, ahead of three commercial American programs, and even after loosing the first round from Fafner in a winning position due to a voltage slip down to 220 while the machine required 240 volts [3]. Mike further played the ACM 1978, the PCW-MCC 1979, and the WMCCC 1980 (Mike 3), which was already mentioned as debut of Mike's successor Advance [4].
