[HECnet] Next retro comms project?

Fred wrote: I thought SNA mostly ran on Token Ring or something? 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 ...) There were also MCA cards for making a PS/2 emulate a SNA-connected terminal over coax. And, BTW, all MAUs are passive. The active device is called a CAU. *shrug* 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. Cisco and Madge actually sold a significant number of devices for doing precisely this, back in the day. Peace... Sridhar
