			differential pair.
C2	3	T+	TRANSMIT + (Output) (Ethernet) - this line is
			intended to operate into terminated transmission
			lines.
A2	4	T-	TRANSMIT - (Output) (Ethernet) - part of a
			differential pair.
C3	5	R+	RECEIVE + (Input) (Ethernet) - a data input sourced
			by the MAU.
A3	6	R-	RECEIVE - (Input) (Ethernet) - part of a differential
			pair.
C4	7	PRSTB*	DATA STROBE (Printer) - an active low output pulse
			used to clock data from the system to the printer.
A4	8	+12VF	+12 Vdc Power - fused on MPU board.
