you wouldn´t have to ship it back. But wait, japan is pal or ntsc?
It should perhaps be repaired in PAL-land, so that another pal user might have it afterwards.
I´m waiting to see what skurk comes up with. There were very few A500 for sale at .co.uk and .de.
@skurk
Perhaps, regardless of which rev board you have, I could send you my ROM switcher and MegAChip for fitting?
I´d reimburse you for your time.
