interesting, I've never realized the 154I could be set for 220V or
240V, I'm going to take a look
right now :)

I made DC-DC boards to replace the C64/VIC-20 power supply regulator,
so I just have
spare boards for this mod. It's quite faster than replacing the whole
thing (including the transformer), it would make the transformer run
much cooler, as it did for the C64 power supply's one.

Thanks for the hints :)
