The PCW (Personal Computer Word-processor) computer series was created by Amstrad and was launched in 1985. Schneider took care of distribution in Germany, changing the name to Joyce.
Features
Every member in the PCW series (but for the PcW16) share the same basic features:
- Z80 processor clocked at 4 Mhz.
- A Gate Array (ASIC) that handles most basic functions (audio, video, memory controller, keyboard handling).
- A i8041 MCU that controls the printer and serves the boot code on start up (as the PCW has no ROM at all).
- 256 KB internal RAM, upgradeable to 512 KB.
- Detachable serial keyboard, handled by the i8048 MCU.
- Expansion capabilities through an expansion bus.
The following items were delivered along with the computer:
- Either a matrix printer or daisywheel printer by model.
- The LocoScript word processor by Locomotive.
- The CP/M Plus operating system from Digital Research, ported by Locomotive, including its well known Mallard Basic.
- Manuals.
History
Alan Sugar had the idea of the PCW while flying to Hong Kong on July 1984. He realized that most computers were used as word processors. His idea was to offer a substitute to typewriters.
To achieve lower costs, the machine was designed around a Z80 processor, with a custom ASIC by MEJ Electronics (who had already worked on the CPC), monochrome screen and without sound. Locomotive was in charge of providing the software for the new machine.
It wa sinitially designed to have 128 KB of RAM, but due to falling RAM prices, it was decided to be shipped with 256 KB. The project code name was Joyce, in honor of Sugar's secretary.
The computer was launched in September 1985, at 399£ + VAT, much cheaper than IBM PCs at the time. It sold more than 700.000 units on the first two years, taking 60% of the UK market, and 20% of the european market.
The PCW's commercial life ended in 1998, with more than 8.000.000 unit sold. It was a very popular business machine, but not as home computer. Its game catalog is really small compared to other contemporary computers.
