6 screws (50) in the upper shield
3 screws (80) in the front of the shield/printed circuit board assembly
4 screws (80) at corners of power supply
3 screws (150) in the round holes (floppy) + standoffs (130)
9 screws (80) holding the shield
4 screws (220) from the square holes (the upper ones?)
3 screws (240) from the round holes (the bottom ones?)
Unfortunately, the service manual doesn't assign each kind (50, 80, ...) to the exact screw type, only lists quantities, so I had to guess it by myself:
50: 6x screw pan head M3x8
80: 16x screw pan head M3*5 (I'm not sure why these are for the PSU, shouldn't that be the longer M3, 50?)
150: 3x screw pph 6-32 x 1"), philips pan head
220: 4x screw self tap M3*7L
240: 3x screw self tap pan HD 3*10, asi pan head M3 10mm
I'm not really an expert on screws (only screw ups
), does that "x8", "*5", "x1"", "*7L", "*10" means height? And if so, why it's a mixture of inches, mms and god know what?
