Adding TCP/IP Ethernet to PIC - how?

[dhouston]

I was thinking that there were some pics that I could run on 3.3 for testing

I did not have that option. I had nearly 100 partially assembled PCBs that were designed for the Tibbo EM202. I used the ZX-40a (ZBasic) as the CPU and, while my board is designed to use a wall transformer (switchmode) supply, the ZX-40a must run at 5V or the software UARTS (full duplex background operation) must be limited to 4800bps. I had to design a 5V to 3.3V adapter board so I could use the nano LanReach, instead of the Tibbo which was discontinued just as I ordered the first batch.

Lots of PICs run at 3.3v... even the 10F series, go ahead and play...
