Subject: Special Circuit Breaker Wanted!

As some of you may know the MACSYMA Consortium will be dissolved come
1 October, and we have been advised to make alternate plans because
the future of the MIT-MC machine is not clear at this time.

I have been making alternate plans for some three years now, and have
new host up on the net which has space reserved to hold all of the
files currently in MC:CPM; and then some, including all the archives
for both lists, and all of CPMUG and SIG/M files...

Unfortunately, we cannot keep the new machine up while no one is
present in the building because we cannot consider the air
conditioning system to be 100% reliable, and the building is in the
middle of the desert...  Thus, we are up only from 8:30am to 9:40pm
MDT weekdays...

So, we have devised a scheme to brute-force cut the power when the
temperature reaches a critical point.  This scheme requires either an
externally controlled three-phase circuit breaker or some sort of
relay-driven crow-bar switch, with a capacity of approximately 75-100
amps per leg!  We have yet to find a solid lead on such a device, and
hope that perhaps someone reading this mail can help.

Address any replies directly to me, and not either list, please.

Thanks,
Frank
