I recently purchased a substantial number of components to rebuild my PC
into a
233MMX.  I was moving floppies, tape backup drive, hard drive, and other
components from an old motherboard/case to a new set.  After upgrading many
systems, I considered myself familiar with all the unfortunate possibilities.
However, I neglected to carefully check the power cable leading to my 3.5-inch
floppy.  It was off by one pin (that is, the pins and sockets were
misaligned).  I was told by the local vendor that the power supply can detect
such a situation on a line and will not power up (a safeguard?).  A quick
movement of the connector and the system booted properly.
