The Olivetti M28 personal computer, introduced in 1986, was the successor to the Olivetti M24. It had an Intel 80286 CPU running at 8 MHz and 512 KB (expandable to 1024 KB on the motherboard) of RAM, featuring a 5.25" floppy drive and a 20 MB hard drive. The operating systems were MS-DOS 3.2 and XENIX.

The computer had room to install three disk units, as opposed to only two on the M24. It was possible to install a 70 MB hard drive, a 80287 math coprocessor and a enhanced CGA compatible graphic card capable of displaying 640 × 400 pixels with 16 colors.

The Olivetti M28 was rebranded as the AT&T PC 6310 by AT&T in 1987 and sold on the US market.

It was available in France as the Persona 1800, sold by LogAbax.
