I tried to make the title as short as possible :-)
A good friend of mine works at the recycle center and there he found a C128 without power supply, I know the connector of a A500 power supply is the same and that a C128 power supply can not boot up a A500. but does it work the other way ?? He does have got a A500 and A1200T at home ... if not, then the C128 may end up under a bulldozer :-o
