According to a transcript of a conference I read (or an  article,  I'm
not  entirely  sure which of umpteen places I read this), the older XL
power supplies were not rated (in terms of current) as  high  as   the
newer  ones   and   XE power supp.  This apparently caused some supply
burn-out problems for people with memory-upgraded  XL/XEs   who   also
had   P:R:   Connection   devices  (which  draw  power from the %V SIO
line), etc.  The upshot was that the newer  power  supplies  put   out
enough   current   to  cure  the  problems.  (1.5A vs. 1A ratings as I
recall...)
