DEC made at least three. The original one is the DECbridge 500, a 3U rack mounted device, 3 or 4 cards, 3 Ethernets (10 Mb/s) to FDDI. See the DTJ issue I mentioned in my previous note. The other two: the DECbridge 900, which plugged into the 900 series modular enclosure. It's about the side of a 400 page hardcover book, FDDI to 6 Ethernet ports, 60,000 packets per second using a MC68040 at 25 MHz. I'm still proud of that. (I wrote the "fast path" packet forwarding firmware.) Then there is the Gigaswitch, a large modular chassis with lots of line cards, some FDDI, some Ethernet, possibly some with other stuff I don't remember. paul
