Nice chip. What's the guide price?

But Microchip's TCP/IP stack is free, as is their IDE with assembler +
simulator. Their development kit is a LOT cheaper, as well. It's largely a
matter of taste, though. I've used PICs a lot, and I have the equipment
available, such as an ICE and a "C" compiler.

In any case, I offloaded the TCP/IP stack to one of these, with the addition
of Realtek PHY chip and a Mag-Jack:

YUK! Not for bare-metal coding, thanks. Java's a fine language on PCs with
oodles of RAM, but any heap-based language really blows goats in an embedded
system without memory management.
