[Coco] Ethernet Port Cartridge for the Coco 3

[Mark Ormond]

That's the same chip used in the arduino Ethernet shield, really easy to setup and with it being in a arduino lib, easy to look at working source code.

Implementing UDP is nearly as difficult as TCP, well probably 90% or so..  You still need the same underlying stack and whatnot.

I think a good approach would be to use something like this:

Cheap, and it provides a decent TCP/IP stack in hardware and connects to the ethernet/wifi interface.  So you'd just have to communicate between coco and the tcp controller at a high level.
