I've seen a couple of these designs using ISA cards now, and it's certainly an easy way to get an ethernet connection. My only concern about using such a system is how long will ISA network cards (or indeed connectors) be available. Remember VESA? I'm still dithering about how best to get a simple (and cheap) way of connecting devices to Ethernet. There are plenty of off-the-shelf solutions from 200USD and upwards which isn't really feasible in the kind of simple, serial-operated remote switch and sensor devices I'm interested in, the Ethernet connection would more than double the cost. Much more in fact. Currently I'm waiting on the new Scenix Ethernet devkit to see if that offers a solution. Most of our devices really don't need anything fancy, just transparently passing data to and from a pic's rs232 via ethernet to a PC on the same network would be fine. Web serving etc isn't needed for most of our applications (though we are looking at one web-interfaced instrument project, looks like I'll need to start learning Java once I've finished on C!) . -- http://www.piclist.com hint: The PICList is archived three different ways.
