"So he put the idea to Mark that they could buy the Swedish PCB, and have a proper run at trying to re-engineer a working Sky Skipper board. Having both boards would give more options for swapping chips around between the two, allowing many issues to be solved. Mark was sceptical, but agreed to give it a shot, and so Alex struck a deal and dropped both boards off with him, ready for the guy to work his magic, and try to reverse-engineer the hardware to resurrect Sky Skipper as a working PCB."
I'd like to know what the security chip differences are. If you can go to Popeye from Sky Skipper, it should be close to do the same in the other direction.
