Where do I buy?
Follow the directions from their website to install the Demo version of MorphOS2.5 on the compatible hardware that you own and then, while running MorphOS2.5, follow the directions on how to register using the register tool. It will ask you to send an email, you will receive an email in return that shows you how to pay and after payment has been confirmed you will receive another email with the keyfile attached.
I might have messed up one step or another, but that is what I remember from registering a couple years ago when version 2.0 first came out.
There is no telling how long this reduced price will last, so I suggest that everyone that wants a license for MorphOS gets it now. I missed out on the reduced price when it first came out because I did not get my compatible hardware set up in time.
