I am new on here. I am planning to build a Mimeo 1, Apple 1 replica. I was wondering if anyone had any experience or views on using a Mimeo 1 on a 230v 50Hz system (rather than the 115v 60Hz the Apple 1 was designed for).
The recommended Stancor or Triad transformers are obviously no good as they are for 115v systems. I have seen what I think are a number of potential 230v alternatives, but wondered what others have used and whether anyone has any recommendations.
My bigger concern is whether the power supply circuitry on the board can cope with the 50Hz AC system. My understanding (and my understanding is very basic) is that for 50Hz mains, a power supply would theoretically require a 20% larger filtering capacitor than for 60Hz mains given the correspondingly longer discharge time on each cycle. Has anyone experienced any problems running the system on 50Hz mains and has anyone needed to change any of the capacitors?
Finally, I assume that the composite video output of the system is at 60Hz whereas many monitors produced for the UK and European markets were designed for a 50Hz signal. Has anyone had any issues source a suitable display? Again any comments would be greatly appreciated.
