Hi

just had a quick look, some remarks :

 - why is the code in memory.c ? this is not very maintanable, better 
split it in a separate ne.c or similar

 - ethernet traffic is handled by "rerouting" bytes accesses to 
cartdridge space at FAxxxx ; it this how it's done on real HW ? Does 
such NE adapter exist and should be plugged on cartridge port ?

But this means that HD emulation can't work at the same time, since we 
use a cartdridge to emulate gemdos HD drive too.
