[vin36]

The Olivetti M300 was a line of Italian-designed desktop computers introduced in the early 1990s, notable for their modular architecture and support for a range of Intel processors, including the 386SX and later 486DX2 CPUs. Its claim to fame lies in its flexible upgrade options—early models could be upgraded by swapping processor cards, and the series featured advanced (for the time) integrated VGA graphics, PS/2 ports, and support for up to 36MB of RAM, making it a robust and business-oriented PC that reflected Olivetti’s reputation for combining elegant design with solid engineering. While the M300 was not a major bestseller in North America and saw limited popularity compared to contemporaries from IBM or Compaq, it was used in Canadian offices and institutions, particularly in Quebec, as evidenced by vintage computer collectors and users in the region.
