that idea with online devpac manual is really great. can you believe me i'm coding in asm/devpac for about 4 years without one manual for devpac? ;) Especially in debugger are for sure some features hidden to me. (even if i have a desribtion of key-combos). PDF as "starting" format would be great, not much of work and it gives nice result. Do you have this possibility?
About that start for newbie coding: http://mikro.atari.org, check out docs "Making optimized assembly code", motorola.txt (68030 stuff) and maybe some others stuff (memory maps, very good doc is atari compendium in hypertext format)...
