It seems like the message got lost, sorry, here we go again - hopefully. I am in the process of buying a computer. The real problem seems to be the power supply. I am going to be in the US for a couple of years, then I will go back to Denmark. Have anyone tried to rebuild a US-Amiga into an Amiga that can handle 220V and 50hz. The hz seems to be the real problem for most monitors and printers, the voltage can be handled with a powerfull enough transformer. For those who will suggest I buy a Mac SE - I know that it has a "smart" power supply, but the Mac printers don't either. Anyone has some good suggestions. I could sell the whole thing again in some years - but... - Kasper ARPA: kasper@stanford.csli.edu UUCP: kasper@su-russell.uucp Or just reply to the net, as Im real interested in an answer.

(at least in England,Germany, and France). The french ones do handle 220V and 50Hz (and they have vertical resolution of 256 instead of 200) As a matter of fact, I own an American Amiga (I am an early developper), with a transformer for french voltage. I suggest you ask Commodore France (for example) if they have some left. -- *-----------------------------------------------------------------------------* *- Francois Rouaix / When the going gets tough, * *- USENET:rouaix@inria.inria.fr \/ the guru goes meditating... * *-----------------------------------------------------------------------------*

In the latest AMIGA Mail (July/August 1987) there is an article entitled "Traveling With Your Amiga" (by Don Gilbreath and Dan Baker) which details the changes needed. In a nutshell, it requires a whole lotta changes: new Agnus, new crystal, and a new power supply.

If you use the US Amiga with a transformer and an US Amiga monitor, it will work fine on 50 Hz. If you want to go native, you can switch the power supply and Agnus chip, however the composite video won't be correct unless you also change the system clock oscillator, which is soldered in. There is also the issue of the US vs. International keyboard. Sorry, but I don't have a really good answer. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

I have been using my USA-origin Amiga on England for over a year on a 220-110 volt step down transformer that also powers a dot matrix printer and an external 5.25" disk drive. The line frequency causes no apparent problems. -- Bob Duncanson AT&T Unix Europe Limited uucp Europe: mcvax!ukc!uel!bob London, England uucp USA: attunix!uel!bob AT&T MAIL: BDuncanson

V1.2 automatically recognizes which side of the ocean it is on. I am using an European Amiga1000 together with a European Commodore Monitor in Canada with no problem, and of course I still get 512 lines intead of 400 in interlaced mode!
