Joyce/MacOS - Amstrad PCW emulator.
v1.1.2b2 - August 28th, 1997
Joyce/MacOS appears to run the only PCW software I have been able to
locate
personally, namely LocoScript and CP/M. However, due to a faulty CD-R
disc,
the source code to the Macintosh port of Joyce has been lost. I
presently do not
have the motivation to redevelop the Mac port from scratch.
