A hu is two inches, right?

It's actually some uneven number that's around 1.5.

 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?
