	There is another problem that will do this sometimes.  For
some reason Atari forgot how to solder for awhile (wave broke or
something).  Some machines have the most atrocious soldering ever and
this will sometimes break free and make a real mess.  It will often
masqurade as a thermal intermitent problem

	If changing P-supplies fails to solve the problem then check
the solder joints at the power socket, then on the ram chips
(specially if you have an upgrade) then the processors...

	Be seeing you
