Prodest PC 128S

The Olivetti PC 128S was exactly the same machine as the Acorn BBC Master compact. It was sold only in Italy.

Olivetti merely transformed the case design with nice blue and grey patterns and translated all the programs of the original Acorn Welcome disk, as well as the manual into Italian language.

Although it was one of the most advanced 8-bit computer, the PC 128S, like its predecessor, the PC 128, didn't meet a large success, mainly because it came to late on the market, just at the time when the new Atari and Commodore 16-bit machines were launched in Europe.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


just an update... i repair my pc128s by replacing the via 6522, and attached to a lcd tv by modding the original rgb cable (that hadn''t the 5v wire attached!!!). Now i''m fully satisfied with my Olivetti Prodest!!!!
