Probably there is no such thing as "legal" workbench since afaik it is still copyrighted. So just use torrents to download images of wb disks and kickstart roms :)

@lvd

Yep "legal and free" is really requiring too much, sorry :)
I have a legal copy of Amiga Forever 2013 emulation package, so for the ROMs is no problem, I must check if it contains HDFs too.

@alientech,
aside the legal issues, I wasn't that keen to use other people's images, as you never know what can be in them.
so maybe someone else can jump in and help you with a suggestion here?

http://classicwb.abime.net/ -- here are HDFs with any wb at your choice. the only thing it need is original WB disks, which are required during first run.

upd: probably only 3.1+

@lvd

Thanks.

My copy of Cloanto Amiga Forever 2013 did contain the following HDF files, which I didn' t test yet:
workbench-135.hdf
workbench-211.hdf
workbench-311.hdf
