Keyspan USA-28X USB Twin Serial Adapter 2 Port Vintage Mac RS422 Clear

This vintage Keyspan USA-28X USB Twin Serial Adapter is designed for older Apple Macintosh and specialist serial equipment. It connects via a USB Type-A plug and features two female 8-pin Mini-DIN serial ports. Ideal for Macintosh serial peripherals, RS-422/RS-232 equipment, MIDI equipment, and other vintage hardware. Windows detects that a USB device has been connected but identifies it as an “Unknown Device”.Because the correct compatible hardware/software is not available to us, we have not been able to fully test communication through either of the two serial ports. It is therefore being sold as partially tested only.
