Apple IIgs, IIc+ null modem

Approximately 6 feet long, made with shielded cable. Converts the Apple IIgs or the IIc+ modem port to a female DE-9 connector, typical on older PCs with RS-232 serial ports. If you have a PC or Mac without RS-232 serial ports, you would also need a USB adapter, below.

DB25M to DE9F Adapter

For connecting an Apple Super Serial card to a typical PC port, this cable has a 25-pin male DB25 connector on one end and a female 9-pin DE9 connector on the other. It is wired straight through, and so requires the jumper block on the Super Serial card to be pointing towards the word "Terminal." See here for details.

Works with ADTPro transfer software, below.

USD$8.95

USB to RS-232 Adapter

Converts a USB port to a male DE-9, RS-232 connector. This, coupled with one of the null modems above, will complete the circuit from a modern PC or Mac that only has USB ports to an Apple II. Drivers for Windows, Windows Vista, and Mac OSX are available. Note that Windows users will need to map the new COM port in the COM1 to COM4 range if the driver happens to install itself higher, for example COM6.
