Err...too much. I've got some clients running them, and I've done several non-trivial networks using them. They are VME (sorta), and long ago obsoleted. You had a really old one; they matched Motorola pretty close as far as processors, eventually being one of the few big adopters of the 68060. Backplane ran down the middle. You plugged a processor card in one side, and a ports card in the other, for each slot. Ran from, as I recall, a one slot fixed unit to a 13 slot monster (BN/BLN). The OS they ran was loosely multiprocessing, with an image running on each processor card. This allowed you to reboot a single processor board without bringing the whole box down (well...there were caveats, especially if you were running OSPF). Nice boxes, in many ways better than the competing Cisco product. As an aside, unless you were really good at remembering SNMP OID strings, you configured the things with a tool called Site Manager. This is *still* one of the worst pieces of software I've ever used; they've done nothing to fix it in a decade. And every different version of the router code required a different version of Site Manager; little or no forward or backward compatability. It's more complicated than that. That router was actualy produced by Wellfleet, who later merged with Synoptics to form Bay Networks. Bay was later purchased by Nortel Networks, who is now in the process of trying not to go out of business. A search for "Wellfleet router" should give you sufficient info. Ken Seefried, CISSP
