932 PAR-1 vs PAR-2 cables

We offer the parallel port cable in two types -- the difference is which button signals are connected to the eight lines D0 - D7.

RIGHT hand
Blue D0 D0
Yellow D1 D1
Green D2 D2
Red D3 D3
Magenta D4 +BUSY
Blue D5 D4
Yellow D6 D5
Green D7 D6
Red +BUSY D7

If you plan to use the TTL outputs with an eight buttons response device, the PAR-2 is probably the better choice. If you plan to use it with a 5 button response device, then the PAR-1 may be better. -- BenDugan - 30 Mar 2023
