For example cisco/cabletron/crecendo had ethnernet switches with a
FDDI uplink, that you could use.

DEC made one as well, it was that large modular thingie. I used to have
one. Never got it powered on as it was enormous.

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.)

Neat!

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.

I think this is the one I had. Big modular thing. Maybe (and going by
really fuzzy memory here) 8U high?
