... As in adapted for card sharing? :-/Why would you need an ethernet port ?
Just about any I/O port could be adapted to give you what you need.
Fast I/O isn't necessary. The relevant data consists of 16 bytes every 8 seconds or so.... As in adapted for card sharing? :-/
I don't know that much about card sharing so you'll have to enlighten me I assume you need fast I/O for that sort of thing, what else could you use apart from RS232 on that type of box? :S
