Sellam, et. al. As others have contributed, Proteon was an independent network vendor in the 1980s. I'm a little unclear what became their corporate fate, (I forgot about DEC buying source code) but they did eventually come apart due to market forces. They were an early token ring manufacturer, with their own product. When IBM pushed their technology into the IEEE 802.4 standard, they adapted with the market. They also made multi-protocol routers, and since they weren't Cisco, Digital did do some work with them. I had a 4100+ and a 4200 in my development lab. Unfortunately for you I don't think I took any of that stuff home. I was the technical lead/architect for a DECnet Token Ring Data Link specification. As part of that program, I also specified how to interface DECnet-DOS/Pathworks on to PC token ring devices. We worked with Proteon to put DECnet routing support into their routers, and I think they are whom we got to OEM an 802.4 Qbus NIC card for us. (with DECnet VMS support!) This was all to deal with the pressure IBM was putting on the PC and networking business at the time. (my memory is fuzzy on that now.) God I'd love to see what happened to the customers that swore that token ring was so superior to Ethernet that it was going to rule their networks going forward. IBM put some interesting crocks into their LAN chips wrt multicast addressing that really messed things up. I'm glad to see that chapter of history closed. I may be able to make some personal contacts to see if they have anything around. I woundn't be suprised if there is a Proteon old users/collectors group out there somewhere.

I'm guessing Proteon was an independent company until DEC bought them at some point? Just guessing. Anyway, if you've got a set of manuals I'd be interested in purchasing them from you. Please contact me directly if you have some.
