    Thanks for the tip. The oscillator is fine. All the regulators seem fine except U6

    u5  3.3V       # the ground pin is not the middle one like you said here https://videogameperfection.com/forums/topic/ossc-1-5-trouble/
    u6  0.12V     # the output pin has a ~1 ohm resistance to ground. Some kind of short?
    u7 1.9
    u9 1.8

    u12 1.2
    u13 2.5
    u14 1.2
    u15 1.8
    u16 1.8

    What could that mean?
