Anybody undertaken this? Looks like all you'd need is a PAL VIC chip and a different crystal.
Yes, the tech from The Other Group of Amigoids in San Jose, California did this to his personal C128DCR. He urged me to do it, too, but I already had a plastic C128D from West Germany.
I don't have a PAL monitor.
Finding just a multi-standard composite monitor for the 40-column mode of the PAL C128 is a little bit easier than finding a PAL combo monitor which would handle the 40 and 80-column mode of the C128.
With the former, certain cheap LCD televisions with composite-in may take PAL. Unfortunately, because they are so cheap, they are not kept in stock very before they are replaced with something else. You'd have to go to each likely LCD t.v. and test it out. (Several years ago, I was shopping for a multi-standard t.v./monitor at local stores, and to test each t.v. I'd use a PAL version of the C64 DTV joystick.) An easier way, though expensive, is to shop those companies that specialize in selling multi-standard t.v./monitors. Those companies charge high prices, probably because they sell name-brand items instead of cheap, no-name t.v's.
With the latter, 40/80-column multi-standard monitors are harder to find. I use a Sony GVM-1311Q, which is not manufactured anymore. The picture is extremely sharp in either PAL or NTSC mode. I suppose its cousin, the bigger Sony GVM-2020, would have the same sharp results.
The audio speaker in the 1311Q is poor, though,
