Looks like I'll stick to the powerpc MPC555 or MPC850 boards that I have found. I'm sure it wont be hard to port these since there are other 850/555 boards in eCos. With regards to the TCP/IP thing, I'm sure I can conjour up something. Why can't the TCP/IP stack be simulated ?? The only thing I think you would need would be simulated physical drivers (eg. ethernet). Thanks, Brendan Simon.
