    Default Source Code for a Z80 Assembler

    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/Softwar...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

    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.

    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.
