Q-Chess 1.0 is a chess program for the KIM-1, from around 1980. The programs requires memory expansion of 8K at $2000.
The chess board is displayed at a TVT-6 (Don Lancaster) video display alongside the KIM LED Display and Keypad.
In 1981 Fer Weber, a member of the Dutch KIM User Club published an adaptation to use the program with a (video)terminal attached to the KIM TTY interface in the Dutch magazine the KIM Kenner Issue 17.
Binaries on tape and the documentation of Q-Chess were acquired in 1981 from Fer.
In March 2025 Hans Otten translated the source of the adaptations from Dutch to English in TASM format.
This makes Q-Chess playable again!
