BTW, which pin is 1 on IDE connector? There is number 1 printed on PCB, but I suspect its 44 actually?
Can I check Alice voltages with digital multimeter (can it break something?)
erm . . . if there is a 1 printed on PCB, you can bet that it is the N.1 :-)
For the flat-cable connector, is the red one.
You can't break anything with a multimeter . . .pay attention do not touch 2 pins at the same time.
