In the past days me and Porchy were contacted by José G. (JP-Retro ,JOSÉ GONÇALVES E PAULO SOUSA Group).They are a group of “aficionados” of Olivetti Prodest PC1, a vintage home computer released in the 1988.You can read more about it here:

There is a Facebook group as well:

He asked us for some help to reverse some secured PLDs (PAL16L8) present on the motherboard of his Olivetti Prodest PC1-DFD (double FDD version) :

Thanks to him and long live to the Olivetti Prodest PC1!

There is a third PAL to be dumped and reversed , this one comes from the HDD version of Olivetti Prodest PC1:
