Recently, and to my surprise, I found out that DAMS had been open sourced a couple of years ago by its author (available here https://github.com/pseguy/dams (https://github.com/pseguy/dams)). This was a very fortunate event, as I'm in the process of learning Z80 asm and I really want to develop on the Amstrad; this is my way of honoring the machine after many years of neglect :-)
Anyway, to help me with the assembler I've created a cheat sheet with all the commands. It's still a very rough wip, but I think it may be useful to someone.
I took all the information from the french manual -- and my knowledge of french is 0 -- so there are probably a lot of mistakes, and I haven't tried yet all commands. I would really appreciate any correction/contributions.
Thanks!
EDIT: Fixed some small typos in the X and G commands
