Joyce/MacOS is an Amstrad PCW Emulator for the Macintosh.
Joyce/MacOS appears to run the only PCW software I have been able to locate personally, namely LocoScript and CP/M. These both run without difficulty. Unfortunately, like Boycott/MacOS, the Macintosh-specific source code of this program was lost forever due to a faulty CD-R. I do not presently have the motivation to start developing this program again from scratch - sorry.
A screenshot is available on the WWW.
Joyce was initially developed for MS-DOS by John Elliott. The DOS version is now a few releases ahead of the Mac version, with some additional High-Level emulation for speed. Joyce source code is available from John on request.
