I have a student from France who is considering buying a Mac while here in the US (at school), but he is concerned about taking it home later. I note on the SE specifications that it is listed as accepting 50-60HZ and two ranges of voltage. Since he will be looking at running 220 @ 50 hz, is the SE directly usable there (I presume there might be a switch internally for the voltage supply). How about the Plus? How about an Apple HD (or Jasmine HD). He would greatly appreciate any information. thanks - -Bob Wier at Flagstaff, Arizona Northern Arizona University NAU Box 15600 *usual disclaimers* Flagstaff, Az. ...arizona!naucse!rwi 86011 602-523-2052

That means that they will automatically switch between 110 and 220; they can also automatically work with either 50 or 60 Hz. The plus will not do this. To run the plus on 220, you'd need a step-down transformer. That's OK for temporary use, but not really recommended over the long haul. Your student should look at the SE. I'm sorry, but I don't know about the hard drives.

Friends and colleagues have successfully used US-purchased SE's and Mac II's without any problem in France. A number of French colleagues have Data Frame 20's which were bought in the US; these have power supplies which have to be switched by hand (move a jumper cable on the power supply board). I can also report that a US ImageWriter II was used in France for one full year with no apparent difficulty, despite warnings from various people that the printer would not like the 50 Hz current. (A transformer was used to step down to 110 V.) Does anyone on the net have experience with 110V LaserWriter I's? Can they be used in Europe with a step-down transformer? I'm worried both by the 50 Hz and by the large amount of power which is required by the LW.

The plus will not do this. A nit: Using conventional terminology, _all_ Macintoshes have switching power supplies. This term refers to the type of circuitry used to implement the power supply. It is possible to design a switching power suppply that does not care whether it is fed from 110 or 220 volt mains. Apple has chosen to do this for the SE. Another term should be used to describe this (dare I suggest 'universal switching power supply'?) It is also quite possible to design a non-switching power supply that does not care whether it is fed from 110 or 220. (Not necessarily efficient or cheap, just _possible_.) +----------------+ !

If you buy an internal drive for an SE or II you needn't worry about power
as the Mac will provide whatever the drive needs.
If you want an external box, buy MicroNet. They sell very nice stuff, with a
universal power supply just like the ones in Mac SEs and IIs. They have good
prices on smaller drives and unbeatable prices on large CDCs and Priams (150
to 620 MB).
