We at the "Stacken" - that's the computer club here, have an old masscomp running RTU 4.0A, too. As everything else, it's long out of contract. It's a 5600 with 1 CPU, 8 ttys and sadly no ethernet at all. So if someone has a surplus supply of EXOS boards - drop me a mail, too :-) Our 5600 has only been up a month, after a long time of "hardware failure". It just indicated "cache memory write error" at boot up. Finally after deciding that powercycling didn't help, I decided that it couldn't get worse and pulled the CPU-board out. Then I firmly pushed in each chip in its socket. After that "exercise" the machine booted without problems. You may "exercise" your EXOS in the same way. (Heat movement makes chips creep up and out of their sockets.) Because of its commercial past our masscomp had just the bare RTU 4.0A - in the last weeks I installed emacs, bash, gnutar and I'm still struggling with tcsh (The SIGCHLD semantics seem to be somewhere between SYSV.III and BSD4.1). In the next months I hope to get it up on the net. Can be slip, can be an old 3Com bord (from a SUN2). What are my odds :-? Good luck with your 5500, I hope to introduce our 5600 as maggot.stacken.kth.se to the net soon. Harald. haba@stacken.kth.se (Club account) d88-hba@nada.kth.se (Student account)
