If it helps I've managed to get the Amos Pro Community edition installed (https://github.com/alain-treesong/amiga_coding_in_amos). I just copied all the files into a Programs/programming folder on Amibench, the files in the S: drive off the adf to the S drive on Amibench, and the amos.library from the libs folder on the adf to the libs folder on Amibench. As for compliling I just loaded the tinyshell.amos as an accessory in the Amos pro editor (I'll take a look at sorting out the assigns when I get chance).
Hope this helps.
Nick.
The only problem with doing this, you could end up messing up Amibench if you overwrite S:Startup-Sequence
