Source Code for a Z80 Assembler

[ziloo]

I am looking for a source code listing of a z80 assembler that is written in
z80 language! It would be a very educational tool for study...!
A listing that is commented would be gold.

Try zasmb from http://www.s100computers.com/Software Folder/Assembler Collection/Assembler Collection.htm.

I had to make a few tweaks for it to assemble under zmac (a z80 assembler written in C that I could bootstrap zasmb from):

; DER: Change include to includ.
; DER: A couple of if debugs statements had labels which zmac didn't like.

ZSM4 from hperaza might fit the bill: https://github.com/hperaza/ZSM4

Also see http://p112.sourceforge.net/index.php?zsm4

A Commercial Assembler called "Zen Assembler" for the Amstrad CPC 464, comes with Source code within the Manual. It'll probably have CPC Specific Code since it wasn't Standard CP/M.

Thank you all for your references :D

I had never heard of TDL (Technical Design Labs) and, if I understand correctly,
their chief engineer Roger Amidon. After looking through their Assembler manual
(as pointed by daver2), I should say it is a very well written document. It is a
textbook example of a good instructional manual. Herb Johnson has done lots of
work on resurrecting their products.
