Turn something negative into something positive instead. Find new markets instead of rely on an old market.
-Create a PDF of the Amiga book and sell it for $5.95.
-If you are paranoid add DRM protection to it (although last year when I researched DRM it was a fairly costly solution).
-Give it away. Yes give away a FREE Amiga e-book and place links inside the book for products. You get a piece of the cake whenever a sale coming from someone reading your book happens.
-Set up Print on demand but release e-book for free. Free version is simple print-forbidden PDF. Off course most users can crack this (one version is to print screen inside OS running PDF with Vmware) mention many time in e-book that printed book is only xx euro. People will want proper book at good price.
