I used 'amiga monitor' by Timo Rossi to write my first 68k assembly.
Then I used a texteditor (anything I had, I think I used c:ed) and the A68k and amigaos 1.3 includes I found somewhere.
What I am trying to say is: The tools are just part of the equation. Anything you can use to experiment and try things out as you learn is enough at this point.
