The Prodest PC128 Olivetti is an 8 -bit home computer that was distributed, in Italy, from 1986 to 1989, by the Olivetti company. The computer was produced by the French company Thomson (MO6 model) and was distributed in Italy, with some changes to the keyboard and the ROM, from Olivetti.
I didn't look for this computer in particular. I bought it together with a large batch of computers in the summer of 2021.
