Installation and using z80pack under Windows XP with Cygwin:Because Windows systems come without any language compilers, scripting languages or a POSIX compatible application interface, a decent environment needs to be installed first. Visit Cygwin, download the setup.exe program from there and let it install the current Cygwin release on your Windows system. A basic system with GNU C compiler (gcc) is good enough to start with and get z80pack working, you can run setup.exe any time later, to add more programs to your system.
If you don't wish to install the X11 GUI you should get the non X11 version of rxvt. The terminal emulation that comes with Windows is not ANSI or anything compatible and best is left alone. All full screen editors, menu driven programs like Turbo Pascal, games and so on are configured here for ANSI compatible terminals. Various X11 terminal emulations are ANSI compatible and so is rxvt.
The command line to start rxvt is:
c:\Programs\cygwin\bin\rxvt.exe -e c:\Programs\cygwin\bin\bash --login -iBest is to create a link on the desktop and edit the properties appropriate.
Please note that only the Z80 simulation, Z80 cross assembler and the CP/M emulation machine can be build. Building the Altair and IMSAI emulations with front panel is not possible out of the box and requires more work.
