	Within the past 24 hours, my MacPlus, configured with 1Mb of
DRAM, an external 800K floppy and an external separately powered 40Mb
SCSI hard disk, has started resetting itself.  Most frequently at power-up
but also after running for periods up to an hour.  When it starts, it will
start coming up to about the smiling face disk and then go down.  Eventually
after much beeping as it re-iterates this behavior it will stabilize and 
will come up for a period of time.  This machine has run flawlessly for 
over 8 months.  It will duplicate this with the SCSI disk removed and a 
floppy boot occuring.  Has anyone ever seen anything like this?  If it is 
just a loose connection, I will find it and resolder.  But if it is something 
else I would like to know.
