Diagnosed off your site ; bought new power supply from you , ( US to Australia in 6 days ) ; swapped it in ; pushed the ram in really hard ; booted up and awaaaay we go . Thank you very much . Even us older folks can follow your excellent guides . Your help was invaluable and I hope to spend lots more time on my trusty old Mac .
