[Coco] Dump/edit memory in OS-9 or NitrOS-9?

[L. Curtis Boyle]

I know Alan Dekok had a special RAM disk device descriptor called /md that you edit memory live - we used for debugging NitrOS-9 from around 1.16 to 2.01. I don’t know if it is still in the current builds or not… you could run DED on live memory with it. (with DED /md@)

For dumping memory, there was the DMEM command that Kevin Darling made, that you would pipe to DUMP.

Simple PEEK & POKE equivalents would work, but something more sophisticated maybe?I discovered dEd for hex editing files on disk.
