You would need 16 8 pin headers, 3 8 pin sockets, 3 485's, 3 2 pin headers, 3 termination resistors, and 19 jumper caps. While not expensive, it would only be practical if you need the abilities of the Ver 2 Zeus because you would be wasting a good ver 1 board if the Ver 2 ability to set the universe by port is not really needed in your configuration.
