Hi Just joined the group as I've been given a 1990 vintage LC.
Unfortunately, it doesn't boot up and looks like a dead/faulty PSU. The PSU, a TDK branded unit, just makes a quiet ticking ticking noise and the measured voltages on the pins are way too low: Orange wire: 0.6V Yellow wire: 0.7V Blue wire: -1.2V (all voltages measured off-load) I was thinking that I could rig up a PC PSU to supply the correct +12/+5/-5V supplies but wasn't sure of the correct connections. I presume that the Blue should be the -5V but which out of the orange/ yellow is the +12V and +5V? I see someone was asking something similar a couple of years ago on this list but the question wasn't actually answered as someone else could supply replacement PSUs. However, I'm in the UK. Can anyone help? Thanks David --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
