Well, I've mostly got windows and FreeBSD systems here, but the machine on 
my desk is Win2K.  (Plus now a single Model B feeding into a TV card on the 
PC..)

That's an impressive network.  Best I ever managed was about eight machines.

I did find the linux econet driver, so will have to look at that to see 
what it does.

Well, I dug out my copy of VS6, and managed to get BeebEm to compile, so 
have been working on adding econet support to that one.  My C/C++ skills 
are rather more rudimentary than for other languages, so the code will be 
quite clear and thus I imagine easily transportable to any other emulator!

I'm about done on the ADLC emulation, and it seems to send IP packets out 
ok, so I just need to work out why my sockets aren't receiving...
