I finally fixed the PCjr. After taking apart the sidecar, I found that the
board had some exess copper left over from when it was etched. I trimmed
the paths where the short was occuring (which was right near a memory IC )
and everything is working great now, includingthe second floppy drive which
was also defunct while the problem was being solved. Thanks everyone!
