I picked up an old Compaq/Network General sniffer box the other day for a whopping $5 (fascinating, considering that in their day these things went for upwards of $10,000). Anyway, it's built into an old Compaq suitcase computer and has an integrated LCD. I pulled everything apart, and it actually uses a separate ISA LCD/VGA card with the standard 31-pin (or whatever the standard is) connector on it. So if you see one of these things around (there're always some on eBay, and I've found them at Goodwill too), you might want to grab it up--there might be a decent LCD controller inside. It would be a good solution for someone with an ISA SBC that could be plugged into a backplane (like the one I just sold).
