Still trying to get those cartoons on Kindle. The ones with no words seem reasonable but I really need each one on a separate page - and Ebooks have no concept of 'page'. When it puts two to a screen, the ones with captions are unreadable.
I think it would work best with cartoons drawn and sized with the Kindle in mind. Some of these predate the ZX-81. Maybe they can be made to fit but I think I'm going to have to size each one individually before loading them.
