The Olivetti M19 is a personal computer made in 1986 by the Italian company Olivetti. It had an 8088 at 4.77 or 8 MHz and 256–640 KB of RAM. The BIOS was Revision Diagnostics 3.71. In the UK it was sold as Acorn M19.[1]

The M19 was sold in South Africa 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.
