Yaze is a Z80 and CP/M emulator designed to run on Unix systems.
The package consists of an instruction set simulator, a CP/M-2.2
bios written in C which runs on the Unix host, a monitor which
loads CP/M into the simulated processor's ram and makes Unix
directories or files look like CP/M disks, and a separate program
(cdm) which creates and manipulates CP/M disk images for use with
yaze.
Yaze emulates all documented and most undocumented Z80 instructions and flag bits. A test program is included in the package which compares machine states before and after execution of every instruction against results from a real Z80. Yaze is independent of the host machine architecture and instruction set, written in ANSI standard C, and is provided with full source code under the GNU General Public License. It supports CP/M disk geometries as images in Unix files or as read-only disks constructed on-the-fly. These disks are indistinguishable from real disks for even the most inquisitive, low-level CP/M programs and can be mounted and unmounted at will during emulation.
You will need an ANSI standard C compiler, prefered is the GNU CC. Yaze was developed under SunOS5 and was briefly tried it under Linux and FreeBSD. You will have to do some hacking if your system does not support the termios tty interface, for example bare Windows machines or the MinGW build and runtime environment.

Additionals about ZCPR source and program code legalization as part of the NZ-COM Z-System and template for ZCPR-D&J:
From Gaby's Homepage for CP/M and Computer History "Z-System Download Form" (Jan 2020): Following a common wish of CP/M users, Jay Sage lately declared that Z-Systems - NZ-COM (for CP/M 2.2) and Z3PLUS (for CP/M-Plus) - can now be downloaded for free. Anyway, he would like to be informed about who (and how often) downloads the files.
