The 1984 classic Psion Chess running on the SInclair QL. In it's day Psion Chess played a very strong game of chess(and still does!) and won a World Championship in microcomputer chess. The video was recorded on my standard late model QL connected to a Epiphan VGA2USB capture box via the GBS-8820 Converter board. No sound yet as the QL outputs to an internal speaker.
