Zmac is a Z-80 macro cross-assembler. It has all the features you'd expect. It assembles the specified input file (with a '.z' extension if there is no pre-existing extension and the file as given doesn't exist) and produces program output in many different formats. ODA is an online disassembler for a wide range of machine architectures, including: Alpha, ARM, AVR, Intel x86, Motorola 68000, MIPS, PDP-11, PowerPC, SPARC, Z80, and more! Upload a Windows PE file, ELF, or raw binary and then view the disassembly and object file meta date such as symbols and sections. Z80 standalone assembler (Full IDE at ASM80 Online Assembler). Intel 8080 - Intel 8008 - Zilog Z80 - MOS 6502 - WDC 65816 - Motorola 6800 - Motorola 6809 - CDP1802. An online Z80 assembler and development environment with special features for development for the TI graphing calculator line and ZX Spectrum machines. Z80-ASM This is the official homepage of Z80-ASM. Z80-ASM is a compiler/assembler and monitor (including disassembler and debugger) for the Z80 CPU. It runs under Linux (probably also under other UNIX-flavours) and DO$ (DJGPP version 2.03 checked).

Since February 2004 Achim Flammenkampis the maintainer of Z80-ASM. He did many improvements andbug fixes as well. See the README for quick infos.
On 2010-04-15, I downloaded the current CVS tar-ball of Z80-Asm from November 2006 on a Gentoo (Linux 2.6.23 x86_64) System, running gcc 4.3.4. It compiles without problems, only many warnings (almost all about signed/unsigned pointer argument mismatch). But the binaries work as they should. :)Same effortless success on an Ubuntu 8.04.1 System (Kernel 2.6.26 on xenon) using gcc 4.2.4! Also works now under Ubuntu 11.04 with gcc 4.5.2.News: Since 2018-05-21 the 2.4.1 version is availible. It contains additionally two bugfixes and compiles and runs (at least) under Gentoo (Linux 3.10.25 x86_64) System with gcc 4.7.3 and also under Ubuntu 16.04.9 with gcc 5.4.0.
As you maybe remember: Development until the last Z80-Asm 2.4-pre3 version was on the gcc 2.9.5, and later there were many gcc-'bugs'/incompatibilities, but now it seems okay using the current gcc. But things may change if compiler change. :-/

2004-02-01: you can download version 1.1 updated by Achim Flammenkamp. It contains several bugfixes and improvements:
- user interface add key = to change the registersA,B,C,D,E,H,L,IX,IY,A',B',C',D',E',H',L',I,(F')
- display and update the cycle counter and the refresh register
- BUG in f_ld LD rr,(nn) [only 1 byte loaded] fixed!
- BUG in f_ex EX (SP),IX break missing runs into EX (SP),IY; fixed!
- EI replaced by IFF1 & IFF2 (correct LD A,R & LD A,I)
- user interface @(reset), #(clear memory), *(clear all cpu register),$( clear tick counter), &(SP init)
- console.c: BUG in c_init() use term_setting not undefined t fixed!
Here you can downloadPetr Kulhavy's latest z80-asm version.
On 2001-09-30 he put this version for download with these bugfixes (compared to version 1.0):
- ld a,(bc) and ld a,(de) were 'illegal instructions' in compiler
- ld a,(hl) and ld a,(bc) were executed as ld a,l
All these packages are tared and gziped files.
Each Z80-ASM package contains a compiler for the Z80 assembling language and a monitor including an interactive debugger.Compiler is a two-pass one, which knows all documented Z80 instructions. It haslabels, comments and since 2.1 can even evaluate constant arithmetic expressions. For Unix/Linux folks, here is the newest troffed z80-asm manual.Debugger is interactive, it shows content of all registers, memory,stack,program. You can trace program, trace it step by step, modify program,registers and content of memory, load and save parts of memory and of course set breakpoints.
The (default) look of z80-mon (click for help screen):
To install the Z80-ASM you must do following:
- download and unpack the archive
- change into the just created z80-asm directory
- read the INSTALL file
- according to instructions you've read install the Z80-ASM :)
but typically a 'make' will do what you want.
Z80 Assembler Online
Besides the raw Z80-CPU with 64 KB RAM this Z80-ASM-Package also supports a quartz for the CPU, IO-buffering logic, extended memory banking, a Z80-CTC and daisy-chain interrupt-logic. Moreoverthere is an LCD-display and a hardware clock availible. For details see the delivered hardware/README file.Original author of Z80-ASM is Petr Kulhavy.

Last updated:Online Z80 Disassembler
2018-05-21 23:04 UTC+2webmasterAfter releasing Assemblex IDE, I noticed it's much easier for users to use online tools. So, I decided to create a browser, online (but also available offline) Z80 Assembly Disassembler! The core engine is just like Assemblex's but if you give it a try with huge programs (I tried disassembling zStart 1.1 and it did it in less than a second) you'll notice it's much faster. Mainly because Javascript is faster than Python (also depending on the browser, Chrome's Javascript is the faster).So, where can I find it?
http://www.davidgom.co.cc/z80.htmlRight there! Please give it a try, it's online, no downloads! Please give your opinion on it on this topic
I also have to say it can't open files for now, but that will be included soon (using PHP). If you want to disassemble files use a Hexadecimal Editor like Hex Baker or XVI32 and then copy and paste the code there. Thus, you'll see how fast it is disassembling huge files and applications, perhaps even Operating Systems.
