Olivetti M28

[vin39]

The Olivetti M28, launched in 1986, was notable as Olivetti’s first personal computer to feature the Intel 80286 processor, running at 8 MHz, and it came standard with 512 KB of RAM (expandable to 1 MB), a 20 MB hard drive, and support for both MS-DOS 3.2 and XENIX operating systems. Its claim to fame was its advanced graphics capabilities for the time—supporting up to 640×400 resolution in 16 colors—and expandability, including options for a math coprocessor and up to three disk units, making it a robust and versatile IBM PC-compatible system. It was rebranded and sold in North America as the AT&T PC 6310.
