The Olivetti P6040 was a personal computer, described by its maker as a personal minicomputer. The P6040 was programmable in Mini BASIC and featured a floppy disk drive that used proprietary 2.5-inch sleeveless disks called "Minidisk". It was produced starting from 1977 and was the first microprocessor-based Olivetti computer, the Intel 8080, instead of on TTL logic CPU.^[1]

Designed by Pier Giorgio Perotto, it was presented at Hannover Messe in April 1975 together with the P6060, its hardware used TTL technology. Both had a brown-colored case.

The P6040 was little in dimensions and weight, thanks to the introduction of microprocessor (for the first time at Olivetti).^{[citation needed]}

Another innovation in the model was the introduction of the light-emitting diode display. The design was by Mario Bellini.^{[citation needed]}
