In the early days, modems were 110 to 300 baud and grew to 56K. Serial cards on the Apple II’s max out at 9,600 or 19,200 baud, and the IIGS is officially at 19,200 as well. There have been reports of higher speeds obtainable on the IIGS.

1981 Apple Super Serial Card II
670-0020- (Rev. C on card pictured). 820-0046-D
Used in the Apple ][, ][+, and //e computers with an RS-232-C serial interface. Popular uses for this card are connecting an ImageWriter or ImageWriter II printer or modems, terminals, and other devices. Can be used in the IIGS, but that has serial ports built in. This card would also be used for networking with printers or other Apple II and Macintosh computers.
Available manuals are the Apple II Super Serial Card User's Manual (1985) and the (1981) Apple II Super Serial Card Installation and Operating Manual.
Previous collector removed the short card interface cable from the card for easier storage, I may run across them yet...If you are replacing an existing Super Serial Card, you won't need the cable. Available with and without the card to port interface cable. The card interface cable goes from the card (10 pin plug) to the back of the computer where it fastens into one of the openings, becoming a 25 pin port for the printer/modem cable to plug into.
You will need an additional cable (not included) to go from the back of the computer to your particular device - a printer, modem or other serial device.
Note: Item pictured is representative, the actual item you receive may be a different revision or serial number or even have different colored dip switch blocks..
Network your Apple II's
This is a networking card for the Apple II family. It may only work on a Digicard Server, which I do not have. The card is untested. Update: remaining inventory will ship without the interface cable shown.
