I've got a Keyspan USB Serial adapter, model USA-28. This allows you to use up to 2 RS-422 mini-DIN8 serial devices on a Mac via USB.
I don't have a way to fully test it, but it is recognized by OS X 10.8.3. Includes the box (well worn, and has stickers on it from an educational surplus sale) and software CD as well. Would like to get $20 shipped via USPS Priority Mail to the lower 48 states. Alex Kampe Floyd, VA 24091 -- You received this message because you are a member of the LEM Swap group.
