Converts a Macintosh or PC 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 Mac or PC that only has USB ports to an Apple II. Drivers for Mac OS X (Intel), Mac OS X (PPC), and Windows are available. Drivers are also available from the manufacturer's website. Note that on a PC you 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.
