The Amstrad PC 1512 was launched in 1986. After the Amstrad CPC 464, the CPC 664 and the CPC 6128 (three home computers based on the Z80) and the PCW 8256 and the PCW 9512 (both dedicated word processing computers based on the Z80 as well), 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.
The mouse port, although using 9 pins like a COM port, is proprietary to Amstrad ... The port is female and is only for use with an Amstrad mouse. The special PC-CM monitor provides power to the system unit by a large 14-DIN connector.
Charles Da Silva adds:
Digital Research brought all its support to the Amstrad PC with its DR-DOS, expecting it to know the same success as the CPC and PCW series. The problem is that, near to the launch, Sugar decided to also include MS-DOS, destroying all D.R. hopes to get even on Microsoft...
Andrew Balls comments:
The PC-1512 was CGA-compatible software wise, but the display had a round DIN connector instead of 9-pin D and the signals were different: I vaguely recall that they were analogue instead of digital and perhaps had composite sync. It has been many, many years since I looked at these. The PC-1640 had proper TTL EGA on a 9-pin D.
Rond Ofstad adds:
On the earliest versions of the 1512 model SD/DD you could get a HardCard. It was a controller card with onboard 10 or 20 MB HD.
I had a 1512 with 640K of RAM and 2 DS floppy drives. In those days i was starting my way arround computers, this was my first one. Still remember messing up with config.sys and autoexec.bat to try to address the 640K for DOS games, i even remember creating BAT files, creating menus for some utilities i''ve got from computer UK and US magazines. I have many great memories of LONG hours spending messing up with DOS and games. GREAT machine. To bad i gave it away to a friend many years ago and never seen it again... :(
BTW Jorge Gomes, is there even a remote possibility of getting one these days in Portugal? I think i still have some floppies with the programs i have and i think i still have floppies with DOS 3.1 and DOS 3.2...
Anyway if someone in portugal have one and want to sell contact me by email, pls: joaoerm@gmail.com

Still have my Amstrad 1512 with additional 20Mb HD installed....runs DOS with a text ''graphic'' menu system which my Uncle set up for me years ago.
I think I still have some system disks (5 1/4) so if any one wants a bit of software I can upload to somewhere for download - you''ll just need a 5 1/4 disk drive ..... or if I have a spare disk I could post
Great PC with many happy hours spent playing games etc
