Hi,

I have been given a Mac Plus 1Mb however it does not power up. I have checked visually the components on the boards, there do not appear to be any blown caps, I have unplugged and re-plugged all connectors. When I turn it on, it makes a "chirping" noise. Am I assuming correctly that this is a power supply related issue. Thanks for any directions to try get this computer up and running again.

cheers,

Wayne
