As there are probably plenty of Amiga owners without the original Workbench and Extras disks, I've been pondering the issue of software license.
To my understanding, each first hand sold Amiga set has been issued with WB and extras disks. Now, let's say that you purchase an Amiga 500 that has Kickstart 1.3 rom but no OS disks. Does the fact that the computer in question had these disks originally give you the right to i.e. download the disks as adf images from the Internet or to copy them from another source? In other words, is the license for the software in the computer that you buy or not? At least to my understanding the software license isn't attached to the media containing the software. I.e. if you have a valid software license for Windows OS, you can install the OS from whatever installation media containing the OS and not necessarily the media issued with the license.
I'm in a similar situation mentioned above with my A500 but I purchased the AmigaForever bundle to be on the safe side.
