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.
