1070 monitor at 50Hz AC
« on: March 27, 2013, 02:49:30 AM »
Recently I bought an Amiga bundle that included an Amiga 1000 and a 1070  monitor. Both the 1000 and 1070 are US models, meaning they need 120V  at 60Hz. I live in Australia where 240V at 50Hz is used (technically,  it's 230V +10% /-6% but the grid is commonly supplied with 240V since it  is within tolerance).

With the bundle I also got a transformer  to take the mains down to 120V. The owner said he hadn't used it for  years. I don't have the proper lead so I'm unable to test the  transformer (will it still work?). And besides, it's big and heavy so  I'd like to find something smaller and lighter. Problem with these 2:1  transformers is that they have the same frequency on the primary and the  secondary side. If I want something that can change frequency I have to  pay a fortune.

My question is, how will the Amiga 1000 and the  1070 monitor react if I feed it with 50Hz AC (at 120V)? Will it affect  anything? I think the computer might be ok since internally, it's just  DC. But what about the monitor? Does it use the 60Hz as some kind of  sync or anything? And can I use the 1070 with an Amiga 500?

Thanks for the information! Yep, I do have an RGB cable. I will see if I can get the transformer I already have to work. And if the monitor and A1000 works then I might get a new and smaller transformer. I think a power rating of 300W should be enought but maybe go for 500W just in case? Would this be enought for an A1000 system (I might modify it) with a monitor?

All these years I never heard of a 1070 monitor.  Wow.   I remember the 1702 monitor I used with my C64.  Then there was the original 1080 for the Amiga.  How can I possibly not remember the 1070?  This is really weird.

Apparantly, The 1070 model was released together with the Amiga 1000. Check out this link with a list of Commodore monitors:
