The electronics is composed of two superimposed cards. The top one holds the power supply and video circuitry, the bottom one holds the logic circuitry.\
|
||
The electronics of the PCW series was very reliable. Most of the PCW machines one finds nowaday are still running well, except for the 3" drive belt which releases and have to be replaced regularly.

The letters you send speak volumes for your company's image. Scrappy typing, untidy layouts and poor spelling announce that you're less than professional outfit.\
|
||
Whereas beautifully presented correspondence shows quite clearly that you're a company to be reckoned with.\
|
||
Now Amstrad's new wordprocessor with daisywhell printer and spellcheck facility means that any company can produce superb quality letters, reports and documents.\
|
||
With the minimum of effort and for a minimal outlay.

The Amstrad PCW 9512 was a dedicated word processing computer. It was the successor to the [Amstrad PCW 8512](/museum/amstrad-pcw-8256-8512/) and had the same basic characteristics. However, it corrected two of the main criticisms of the 8512: the low quality of the printer and the machine's non-business-like styling.
|
||
|
||
It had a paper-white monochrome screen (black on white) unlike the 8512, which had a green monochrome screen (green on black). It was equiped with a 3" 720k floppy disk drive (a second one could be added) and used a daisywheel printer instead of the dot matrix printer of the PCW 8256/8512.
|
||
|
||
Like the previous models, it could run CP/M+ and was supplied with the Locoscript V2 word processor including LocoSpell and LocoMail, and Mallard Basic, both made by Locomotive software. DR Logo was also supplied as standard.
|
||
|
||
In 1991, two new models were produced :\
|
||
\- A cut-down model called the **PcW 9256** (same characteristics, but only 256 KB RAM and a 3.5" disk-drive) which was a replacement in the PCW range for the PCW-8256.\
|
||
\- The **PcW-9512+** which replaced the PCW-9512. It was almost the same machine but with a 3.5" 720K drive.
|
||
|
||
Finally in 1993, these models were replaced with the **PcW-10**.
