Yeah if I was you id be stocking up on a few logic boards and even old mac pluses that you can gutt for the power supply and analog board.

Are there any other Australian 128k owners here?

Or Lisa owners for that matter, I did have a Lisa 2/5, running system 5 with the unmodded screen kit (tall trash can)

I am hoping to find ether a Lisa or Mac128k to relive the good old days again.
