During the early and mid-80's I was a member of Novell's technical staff during and had a good working relationships with several Proteon engineers. Novell, of course, had PC networking software and was working with just about any and all PC networking hardware vendors to make sure that there was a NetWare driver for their gear. At that time, Proteon had their own flavor of token-ring over twisted pair style hardware call Pro-Net. I don't remember the details or the transfer rates, but it was not particularly successful and later Proteon ended up joining the shift of the industry to Ethernet. Somewhere along the way, in the very early 90's, I think, they combined with 3Com. If I remember right, Proteon was located in Waltham, MA during the 80's. - Jared
