Just Assemble Z80

This program is a simple assembler that assembles Z80 assembly to Z80 object code.

NOTE: This assembler is not a complete assembler, it only supports main instructions, extended instructions and bit instructions. It doesn't support IX/IY instructions!

Set-up

Prerequisites

To use jaz80 you need premake5, make and gcc.

Building and running the assembler

To compile the assembler you must first run the command premake5 gmake2 in the project directory. After that, run make.

The assembler will be compiled to bin/Release/ but you can move the binary to wherever you like. The assembler only requieres a source filename, which should be a path to a Z80 assembly file.

Example: ./bin/Release/jaz80 asm-tests/test-6.asm -o test.com

Testing the assembler

To test the assmbler you probably want to use a Z80 emulator and use one of the many tests provided in the asm-tests directory. The tests use some CP/M test functions (such as CP/Ms print function).

After assembling and running the test-6.asm the Z80 emulator should output:

Hello, world!
Hello, world!
Hello, world!
Hello, world!
Hello, world!
Hello, world!
Hello, world!
Hello, world!
test 1 executed succesfully!
test 2 executed succesfully!
test 3 executed succesfully!
