Or the $25 DB9-Ethernet Wiznet adapter.

Wiznet is the chip in the official Arduino Ethernet shield.

We need help here. My tinkering is just turning ethernet in to serial, so like dialup speeds. Fine for a computer that only existed during those days ;)

Boisy Pitre's experiment to hook Arduino IO pins to the CoCo bus is what we need. Have you read his webpage on this? Great stuff.
