Amstrad
PC 1512

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.

Surprised that the PC1512 is 1986 vintage! My mum and dad bought a PC1512 HD20 from K Mart in 1991 for around 1400 Australian dollars. You couldn''t buy a decent computer (386, 486) for under $2000 at the time so this was it. But it carried my mum through university from 1992 to 1995, using the Ability software package, which combined word processor, spreadsheet, database and modem communication software. I learned some MS-DOS (and so did my mum!) using the included tutorial disk. The computer eventually broke down in 1999 - the hard drive had failed but a replacement HDD was hard to justify because we didn''t really need the computer, and I thought a replacement would be hard to find and/or expensive. It wasn''t much but I have indispensable (to this day!) knowledge and a foundation in computers because of this thing.

My father bought the Amstrad PC1512 in 1988, just a year before I was born. 22 years later and the computer still works perfectly without any blemishes. I grew so fond with it that I kept and maintained it over all these years$ today I not only regularly play old classics like Digger (Play it over at http://digger.org!), Castle Adventure, Q-Bert and others but I also have a small library of games and programs I made in GW-Basic for it. Some of the programs I even released online on my website. I hope my precious old jewel survives for decades to come!

My father bougt himself an used Amstrad PC1512 in 1993. Although I never really understood why he did that (I also shared a brand new 486 with him), this machine was one of the most interesting and amazing computers I have ever seen. We replaced the B-floppy by a 30 MB NEC hard disk which looked quite odd (black panel) but worked perfectly.
Though it was far away from being a high-end pc, its strange features made me love it. First, the clock and calendar was powered by 4 AA-type batteries being placed on top of the case and only covered by the monitor placed above. The loudspeaker was not simply a beeper, it war REALLY loud but could be reduced by a volume potentiometer placed beside it. On the backside of the Keyboard there was a 9-pin joystick connector to support a joystick built for Commodore and Atari systems. It was no real pc-type gameport (which used a 15-pin connector) but only offered the possibility to use a joytick instead of the cursor-keys that were disabled when a joytick was connected. Anyway, it was fun to use the joystick instead of the cousor-keys, also Commodore-type joysticks were cheaper and did not need to be calibrated.
The case itself offered a wide empty space, I never found what this was for.
I loved this machine but sadly my father didn''t. Only about one year later he replaced it by a used 386 pc.
