I would be happy to purchase update (3.1.4) for my A2000/030 (currently running classicWB advsp) and A500s (3.1).
That is, if it was a fully functioning OS as classicWB tries to be, with all the patches and bells and whistles. I would rather pay then have to install this stuff manually. Too much to hope for?
Running OS 3.9 on the 2000 used a lot of resources without anything running and was a good starting point, but required a lot of additions, patches, etc. to get it up to snuff.
3.1 is just a blank slate.
Well, I would probably still purchase it even if it was just a modest update. These were just a few thoughts.
