I just cracked open one of our new SE's in order to find out whether or not the new power supply is set up internally to accept 230v (European). I found a sticker on the outer metal case surrounding the main assembly which said: Input: 115v ~ 1.2A 230v ~ .75A 50/60 hz But nowhere did I find a switch/jumper etc. that would allow the supply to be switched from one to the other. Does this mean that it auto configures and that when I take the beast with me this summer to France I need only obtain and plug-adapter? You better believe I want a conclusive answer before I go! Any help would be appreciated. (You listening Apple?) Thanks in advance.

This is also true of the Macintosh II; its monitors will also work at 140 to 170 volts, if you can find an outlet with such a voltage. :-) -- Joel West {ucbvax,ihnp4}!sdcsvax!jww (ihnp4!gould9!joel if I ever fix news) jww@sdcsvax.ucsd.edu iZSE .UUCP>

What this implies is that somewhere internal there is a switch (or solder jumper, or something) that allows the supply to be set to one of the two ranges mentioned. It does NOT say that you can plug it into 110V or 220V, but not 150V. It does say that voltage is the only necessary setting, and that frequency is not an issue. I don't know what the SE internals are, that's your disclaimer. I DO know from experience that this is typical marking of a supply intended to be switched internally between two or more flavors or power. -- -Brian Diehm (SDA - Standard Disclaimers Apply) Tektronix, Inc. briand@tekig4.TEK.COM or {decvax,cae780,uw-beaver}!tektronix!tekig4!briand

Someone who has an SE can correct me, but there is not external switch.
I sincerely doubt there is an internal switch, from other information I've
seen (the Byte article).

But I found no switch or jumper -- and why would Apple use two transformers, which I did find? >I don't know what the SE internals are, that's your disclaimer.
