rdf:langString The Olivetti M19 was a personal computer made in 1986 by the Italian company Olivetti. It has an 8088 at 4.77 or 8 MHz and 256–640 KB of RAM. The BIOS is Revision Diagnostics 3.71. In the UK, it was sold by Acorn Computers as the Acorn M19, with additional software also available via Acorn. In France, it was available as the Persona 1300, sold by LogAbax. The machine came with three operating systems: MS-DOS 2.11 / 3.1, Concurrent DOS and UCSD p-System. It is capable of displaying graphics in standard CGA or Plantronics Colorplus mode (320x200 pixel with 16 colors and 640x200 with 4 colors). The M19 was sold with two floppy disk drives (360 KB format). A hard drive option was made available later, in the form of a 5 MB (later 10 MB) hard drive in an add-on case (aka "sidecar") attached to the left hand side of the computer by four machine screws. Paul Maynes, a technician at HBH Computers (one of Olivetti's dealerships in Durban) designed, and SA Signals Manufacturing (also of Durban) produced a bus extension card with a 90-degree bend (purportedly a world-first) that could accommodate a Seagate hard drive controller card. This allowed the second floppy drive to be removed and a 20 MB (later 40 MB) full-height hard drive installed in its place. * Olivetti M19 with external I/O box attached * Olivetti M19 rear view * Inside of the computer, with two 5 1⁄4-inch disk drives * Mainboard.
