Amstrad decided to make its first low-cost PC clone. It was a great European success, capturing more than 25% of the European computer market (impressive now and phenomenal then).
This cheap computer was, however, complete and offered more than some others did. The small power supply (57 W) was integrated into the monitor.
Eight models were offered: The PC 1512 SD/DD (with one or two 5.25" floppy disk drives) and two models with hard disk (HD10 with 10 MB hard disk and HD20 with 20 MB hard disk). FD and HD versions could be acquired with a monochrome or colour monitor.
The Amstrad used an "enhanced" CGA graphic mode, which could display 640x200 pixels with 16 colors (or grayscale). It was sold with MS-DOS 3.2, DR-DOS plus 1.2 (an operating system from Digital Research), GEM (a graphic interface, also used in the Atari ST, TT & Falcon), GEMPAINT and GEM BASIC.
