The parallel fischertechnik interface has a 20pin cable. The supported computers have different pin-outs: 25pin DSUB (PC/Amiga/Atari), 34pin Edge (CPC464/CPC664), or 36pin Centronics (german CPC6128). To solve that, some cables have a N-pin connector on a 20-pin cable. Others have a 20-pin connector, with additional 20-pin to N-pin adaptor.
