They they are parallel chips with many cores (128 IIRC) with small amounts of 'stack' RAM running Forth directly. Chuck designs them 'by hand' using Color Forth, a transistor simulation model and ... Forth words. Similar to the machine found in TIS-100: http://www.zachtronics.com/tis-100/ http://www.zachtronics.com/tis-100/
