[comp.sys.mac] 220V question

kishon-amir@CS.Yale.EDU (Amir Kishon) (03/27/89)

1. Can I use an 110V/60hz ImageWriter II/LaserWriter II in a 220V/50hz country 
   (using a converter from 110 to 220)? any experience? 
2. If I can, can I use Thuderscan with such an IW?

Thanx,
-amir kishon

Howdy -- seems that there are lots of questions like this on
the net right now.

Anyway  -- Imagewriter I or II will work on 50 Hz, 110 V;
	-- LaserWriters (accd. to Apple) will not - you need to
	       have the power supply swapped out;
	-- Thunderscan - sorry, don't know.

I've been using a Mac Plus, IW I and 65Mb Seagate drive here
since Oct. 86 using an industrial grade 220 to 110 V step-down
transformer with no problems whatsoever.

I'll be glad to provide any additional info you might need - 
please email.

good luck, Bryan

I think you meant 220V :-).  110V 50 Hz would be a pain to find, I think :-).

ImageWriter II also, according to Apple "won't work"; mine does just fine, 
however, with a step-down transformer.  For a Mac and an ImageWriter you'll 
need 250W or so.  LaserWriters also aren't supposed to work like that, but I 
know one LW in Germany where I used to work that's been doing it merrily for 
over 3 years now...ignorance can be bliss, I guess.

A ThunderScan takes power directly from the Mac, so it works just fine.  I
ran one on my U.S. Mac operating on 220V in Germany while I was there.
