I thought I'd share this:
FTDI Chip has been discussed on the list before, they specialize in small
USB bridge IC products, and have virtual COM port drivers for just about any
major operating system.

What I didn't see talked about before were their cable assemblies. They've
got ready to splice RS422 to USB cables with the IC built right inside the
molded plug. If you can cut and splice wire, you should be able to easily
add USB support to a Newton.

This item is well stocked and can be ordered from Digi-Key, Mouser, etc. for
around $35. Makes for a very clean USB connection to the MP2x00, assuming
you've got an interconnect adapter or equiv. No need to open the case and
add a board.
