Hi Neill,

Broken or working is fine. I have one that is missing the PS completely. If
I get a broken one, I will fix it myself - it's probably just a case of it
needing to be recapped. I have a working Classic too and yes it's a
different power supply (300-1101) - I need the IPC/IPX PS, 300-1055. I see
you're in AU. There is someone here in the states who has offered one but
I'm giving him some time to get back to me. If that falls through, I'll
take you up on your offer. And thanks for the links.
