Alright, I got the capacitors changed on almost all of the computers. Good news and bad news so far.
Good news is that every computer so far that was working is still working after being recapped and also my Mac classic II is now working! So I increased my vintage Mac collection by one :D Bad news, the quadra is still hanging at the gray screen. When I got to recapping and cleaning the quadra and 6100 the backs of the boards were covered in this white ish colored powdery stuff which I cleaned with a high percentage alcohol. > On May 19, 2015, at 12:16 PM, Jeff Walther <[email protected]> wrote: > > > >> On Tuesday, May 19, 2015 at 11:14:31 AM UTC-5, Jeff Walther wrote: >> >> >>> On Monday, May 18, 2015 at 11:37:37 AM UTC-5, Violet Cloud wrote: >>> After washing it it still only shows the gray screen. >> >> Does it make the start-up sound?
