Hi, I just wanted to come here to say this thread helped me restore an Olivetti PCS 11 I obtained. I replaced the 2 4.7uF caps on the ceramic daughter board inside the PSU and it immediately started working. The symptoms before this we 3 pulses spaces about a second apart with a hissing sound coming from the PSU, it attempting to power up and then giving up. This was my first PC as a kid so very happy to get it working.
Mine seems to have the original Olivetti welcome and tutorial software on the HDD still working. Im planning to make a backup of it, before formatting and reinstalling msdos and windows 3.1, wolf 3d and doom!
