There was a gs/atm and a gs/fddi. I cannot remember fast ethernet for the gs/fddi.
Mainly because we used Dec hub 900 modules to step down to regular ethernet, fast ethernet
only for alphas.

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.
