    Macintosh LC with Pico-PSU boots without -5v ?

    So my LC PSU is bad (smells bad to & gets stupid hot). I will try replacing caps but if something else is wrong I'm using a Pico PSU.

    Macintosh Centris 650 (Green tint)

    Is this just a sink on green issue? My 4:3 LCD this happens sadly. I ordered an original video cable as I can an original VGA convert I'm going to try next. But are there better 3rd party VGA converts that work better? I'm using a Griffin 1-8 switch one at the moment.

    SE/30 old hard drive hack ;p

    So I fixed my SE/30 hard drive. 1) Opened it and fixed sticky motor. 2) These drives work much better facing upward (not upside down). 3) Secure with hot glue (works very well) I'm sharing this in case your not working drive might be fixed by flipping it the right way.
