Portable computer, 1987, Olivetti. The M15 Plus is the improved version of Olivetti's first laptop, with a backlit LCD that made the screen readable indoors and a configuration with one floppy drive and a 20 MB hard disk in place of the second drive. The rest of the machine is the same as the M15: an 80C88 processor with 512 KB of RAM, MS-DOS 3.2 and the case designed by Michele De Lucchi.
