I would think Ben and / or LongHorn Engineer did the basic system code and board firmware though, which I assume he's referring to. Either way, even if Fawzma did it, it's still defunct as they've now moved on to a totally different system.
Quoted from dung:
I'd be interested in looking at the code. Just wonder what language it was done in. Pretty sure ben open sourced the boardset and basic code, just haven't had a reason to dig into it.
I think this was true, and game code itself for AMH was open source ... but the former was withdrawn and the latter's later versions closed, I think in part due to the HomePin saga. I would hope though, if Spooky / Ben etc were amenable to it, enough could be disclosed (even if it was only to parties who had to prove legitimate interest) to make further support or evolution of the game through the community possible.
PinHeck being end of life does have its advantages, if this comes to pass - they or anyone else are unlikely to open source the code on their current system. Also, I think Ben is working on a completely new board system that would compete with or replace the FAST & PROC systems, so perhaps the concerns about PinHeck being used / abused by competitors is now no longer so relevant.
