Name:	Apple SSC
Type:	Super Serial Card

Short description:
	The SSC gives the Apple ][ a serial port (RS232). Up to
	19200 baud are possible. Full handshake is supported.

Installation:
	The card plugs into Slot 1, 2 or 3 of the Apple. Slot 1 is
	usually for a serial printer (Imagewriter), Slot 2 for a
	modem and Slot 3 for a terminal.
	The DB25 connector goes to the printer/modem/terminal line,
	the 10-pin connector on the other side of the cable goes
	into the cable socket at the rear side of the card.

Jumper settings:
	The card has two jumpers and a additional jumper block.
	The jumper block can be installed two ways:
		1) Arrow pointing towards the word TERMINAL
		2) Arrow pointing towards the word MODEM
	Jumpered as MODEM, it will wire thru, jumpered as TERMINAL,
	it will twist 2-3, 4-5 and 6-20 (called null modem).
	The jumper switches are called SW1 and SW2, the switches
	are numbered SW1-1 to SW1-7 and SW2-1 to SW2-7 from left
	to right.
