Looks like it takes 240v. Can it be changes to 120v I wonder? I'm not really
into micro's, but I do remember the Ohio Scientific stuff vaguely....

This is sort of a heads-up. Even though I am the
actual "seller", I'm
really putting this item up for a close friend. I'd buy it myself if I
could, but I'm in an anti-aquisition mode myself. It's an OSI Challenger

There are some nice piccies even if you're not interested in bidding.
HI to all :)

All you need is a transformer 240V<->120V - these are easy to get,
maybe look in shops where they sell electronics for tourists, or
South American 'visitors' ...
I'ts always handy to have one.

Be careful, at least in the reverse direction (240V
-> 120V). In the UK
you can get some 'travel converters' that are quite small and light, and
which have quite high power outputs (like 1kW). Needless to say they're
not transformers - they're triac-based circuits (a bit like a fixed lamp
dimmer) designed so that heating elements, etc run at the right power
when plugged into them. But the output waveform is not sinusoidal, and it
doesn't have the right peak voltage either.
Of course you are right - when I said transformer, I was meaning exactly
such an ancient <g> device - havn't thought about these other thingys.
> I'ts always handy to have one.
A true step down transformer (especially if an
isolating transformer, but
autotransformers are useful too) is a very useful thing to have on your
bench. I have a few of them to get 110V (for many of my devices that use
said voltage) from UK mains.
I added a fixed 120V installation to my workbench including some
US power outles - when going for US machinery, I want to keep them
unmodified. - Also handy for a first check.

Here's how I'm avoiding this problem for my collection: I'm moving into a
new house and getting 220 installed where my stuff it going to be
located.. since it's right where the breaker panel is, it's not going to
cost much at all... so if the computer in question is going to be located
in a basement or wherever the breaker panel is, you don't even need a
transformer... just get an electrician, friend, or do it yourself..
