I found that out the hard way when making a connector for a C64 PSU to check the voltages. Some of the brick-type PSUs didn't show any +5V while a C64 connected to those PSUs worked. After taking a look at the pinouts I found out why, they used the other +5V pin... Gerrit Message was sent through the cbm-hackers mailing listReceived on 2012-09-22 17:00:44
