Home computer, 1987, Olivetti. The Prodest PC 128 S is the Italian version of the Acorn BBC Master Compact, sold by Olivetti after it had taken control of Acorn in 1985. Despite the name it has nothing in common with the PC 128: it is a 6502-based machine with 128 KB of RAM, BBC BASIC 4 and the Acorn MOS operating system, in a two-piece design where the keyboard unit connects to a base containing the power supply and a 3.5" floppy drive. It was aimed at schools and at users of the wide BBC software library.
