My father's old Macintosh ( 128K upgraded to 512Ke ) died recently - no power supply output. Any body got any great tips? I recently purchased Larry Pina's "Macintosh Repair and Upgrade Secrets", got a bit of info, but am not clear on whether or not replacing the two "main" zener diodes on the power supply board will do the trick - they may not be getting any voltage in the first place, by the look of things. Any pointers or suggestions would be welcome. Thanks! -- Tres Hofmeister tres@ncar.ucar.edu
