Swapping power supplies to debug a motherboard

if the fault is good at destroying power supplies. Killing a
power supply isn't going to help the next motherboard if the
newly blown power supply destroys that motherboard, too. Swapping
memory chips between motherboards that are destroying memory chips
is a sure route to frustration and wasted chips. With classic
hardware, there may not be an easy source of extra subassemblies.
Industry standard floppy drives (TM100, etc.) have a write-protect as part
of the drive.
The very first time that I dealt with a malfunctioning Apple][, I
destroyed three boot disks before I realized that that controller and
those drives could wipe out disks even when write-protected.
