  • Its large, expandable case and extra ISA slots made it highly customizable; enthusiasts have retrofitted them with modern upgrades like SCSI hard drives, VGA cards, and Sound Blaster audio.
  • The M240 was sometimes humorously referenced for being “all made in Italy,” and its scarcity today makes it a prized collector’s item among vintage computing enthusiasts.
  • Olivetti-branded peripherals, such as mice made by Logitech, added to its unique international flavor.
  • While it didn’t have a widely recognized nickname, it was sometimes called a “super XT” by hobbyists due to its advanced features for an XT-class machine.
  • The M240’s significance lies in its role as a leading European IBM-compatible PC, cementing Olivetti’s reputation for innovation and helping to drive the adoption of open PC architectures in the 1980s
