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.
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.

I meant to say that I have a DEC VNswitch 900XX plugged into a DEChub One MX - there are clearly modular parts to that, but I'm presuming there isn't a FDDI copper module that I would be able to use?

Thanks, Mark.
