I'm not altogether happy that we have wires running all over the building, in fact. At least we're using Emulex CS11s so the wires don't run into the Unibus box itself. (The CS11 puts all the per-line hardware, like line interfacing and UARTs, out in the distribution panels.) -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry

On one multicore (across the flat roof) we lost two tty lines. Now the problem is.. how do you get the distribution panel PCB's apart to service the line components? It looks a fairly final (terminal?!) assembly to me. Our "after the lightning has bolted" solution was to install a low cost RF carrier packet system using a cheap TV co-ax ring. This places yet another (and more serviceable) box between Thor and the Unibus. Oh yes.. and we got the cables down off the roof. Dave Martin @ U of Reading Psycho
