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.

	PAR-1	PAR-2
RIGHT hand
Blue	D0	D0
Yellow	D1	D1
Green	D2	D2
Red	D3	D3
Magenta	D4	+BUSY
LEFT Hand
Blue	D5	D4
Yellow	D6	D5
Green	D7	D6
Red	+BUSY	D7
Magenta	+PAPER	+PAPER

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
