Microsoft SNA server works pretty well for that, and it's easy to find... Many moons ago I had TONNES of machines setup in that kind of manner, with type 1 token ring to boot! (4mbit). Even with Windows NT 3.51 & 4.0 it worked surprisingly well. (SNA Server 2.x was waaay better then 3.x & 4.x IMHO). Anyways it was easy to connect the tokenring to the FEP, but later on we got cisco routers that would do translational bridging and local ack so we moved our SNA servers to ethernet only.. Just remember to flip the bits of the FEP address as the endian is different from ethernet to tokenring. I've also done the netware SNA gateway, but it was living hell to setup... I doubt I could get it to work again...

I have an IBM PS/2 model (something) with both an MCA Token Ring card and and MCA Ethernet - and I even have a passive Token Ring Mau! (and a cable, somewhere ...) Now if I could just find that gateway software. When I had access to a real mainframe, all of the PC's went through a handful of these PS/2's via Ethernet, and the PS/2's had token ring cards in them connected to a real FEP. Fred
