[comp.sys.apple] PROBLEMS W/ MAC PLUS

I am having problems with a Mac plus and 20 Mb SCSI drive.  Randomly, 
the system will restart, sometimes repeating, sometimes freezing, and
sometimes with garbage on the screen.  I don't think it is a heat 
problem, the cure is a <10 sec. power down.  There are many other
systems in the same room so I do not suspect input power.  

I am suspecting the power supply in the main unit, and I would
appreciate feedback from anyone who has experienced similar problems
with a Mac Plus.

Thanks in advance,

I've been working with Macs for four years, first at an Apple dealer,
currently as a Mac-Consultant.  Everytime I've seen the problems
you've described, they could, in some way, be traced to the power supply.

Do you have any special cards or adapters attached (ie Big screen monitor,
speed-up card, etc.)?  Very often these 'daughter' boards draw more
power than the Mac power supply likes to put out.
