Hi all, I am just back from few days of crazy work and had a little time to check the capacitors on the motherboard and on the CPU daughterboard of the Powerbook 100 and make a little list. Please note that I report here what found on the label. For C22 I have a little doubt about the value, I couldn't see it very well
Place Value C6 47 16V C12 1 50V C11 1 50V C13 10 16V C20 10 16V C21 47 16V C22 47 uF 35V C23 330uF 16V C24 47 16V C25 1 50V C26 1 50V C27 47 16V C30 100uF 10V C32 220 uF 25V C34 47 16V C37 100uF 10V C38 100uF 10V C39 4.7 50V C42 10 16V C43 1 50V C102 10 16V C104 10 16V C310 10 16V Maybe this can be useful for anybody with the same machine and also to double chac with somebody else. Does it match yours?
