The idea was to put an Ion (smaller and more powerful than a VIA-C3 
mini-ITX boards) and the I/O board into a CoCo case to replace a dead CoCo.
The I/O board mounts so you can use the old ports in the case for 
plugging things like the joystick or Floppy Disk controller.

The I/O talks to the Floppy disk controller so you can read and write to 
the disk in ways the PC can not.

Yes, the USB I/O board not necessity, but for those that want to use old 
hardware with the system will gives you more of a true CoCo.

I don't know about an Allen Huffman's CoCo 4 site, but CoCo4.com is ran 
by me.
