Z80PCW is one of the most veteran and internationally respected Amstrad PCW emulation projects. It was originally developed by the Dutchman H.M. van der Vliet in the mid-1990s.

This is the international emulator that served as the cornerstone before the arrival of modern options. It was the "Historical Reference Emulator". It represented the first major international effort to take PCW emulation beyond the borders of the countries where the machine was a massive sales success.

The main focus of Z80PCW was absolute efficiency. In an era where personal computer (PC) power was limited, Van der Vliet designed an extremely optimized emulation core to run the CP/M operating system and the LocoScript word processor at real speed, even on machines with i486 or Pentium I processors.

• CPU Emulation: Implementation of the Zilog Z80 optimized for high performance.


• Model Support: Initially focused on the 8000 series (PCW 8256 and 8512).


• Disk Controller: Functional emulation of the NEC µPD765 controller, allowing the use of disk images in .DSK format.


• Interface: Used a simple interface based on text menus or commands (typical of MS-DOS), prioritizing functionality over aesthetics.

It is currently categorized as a "Legacy" or Abandoned project.

• Historical Importance: It was the foundation upon which many international enthusiasts first learned about PCW emulation before projects like JOYCE became the multiplatform standard.


• Current Use: Not recommended for daily use on modern operating systems (Windows 11/12) due to incompatibilities with 64-bit architectures. However, it remains a fundamental piece for software preservation, as its source code served as a reference for understanding communication between the Z80 and Amstrad's custom components.
