I brought my 128K->512K->2M Mac to Germany last year with my ImageWriter I and
Apple HD20; all worked on a 250W transformer with no problems whatsoever.
Technically the HD20 didn't need the transformer--it takes 70-270V, but I
wasn't about to tamper with a working system.

The ImageWriter I had no complaints--according to official Apple specs, it is
the IW II that is cycle-dependent.  Has anyone verified this? 

The reason I question this is that under the same listing of cycle-dependent
was the LaserWriter, and the institute where I worked had a U.S. LW (later
upgraded to a Plus) running off a transformer, no cycle conversion, without a
hitch.  Ignorance is bliss, I guess...

On the Int'l vs. U.S. analog boards: yes indeed, there are two.  I learned the
hard way.  Int'l is manufactured in Ireland, source of all the European Macs,
and has one jumper (W12 if I remember correctly--it's labelled 120/220V) that
decides what voltage.  BEWARE--the U.S. analog board has the same jumper, in the
same place, with a DIFFERENT function!!!  Like I said, I learned the hard way.
That ambiguous point caused me much, much grief...

Thank goodness Apple has set a new wonderful direction with the SE/II power
supplies!  Now if only they'd do that for my ImageWriter II...  Any comments
about the new LaserWriters?
