Who would have thought that this small, cheap and unassuming piece of hardware could have been the catalyst for a world record that has stood for 32 years? The feat in question was one achieved by Artic Computing’s ZX81 title – 1K ZX Chess, a game that amazed all by only taking up 672 bytes of memory when it was released and has held the record for being the smallest game of chess on any format for the last three decades.
That long standing record has now been finally broken by the demoscene group Red Sector Inc. who have programmed a fully-playable version of chess called BootChess using just 487 bytes.
Our congratulations go out to Red Sector but we are still in awe of David Horne for that amazing achievement way back in the early days of home computing.
