The adapter cradle for the tiny chips looks handy!!! I like that, good find!
I'm not an electronics genius (yet lol) nor do I pretend to be, but just on initial thought I'm thinking that that A5 and 98c boards are going to be completely different and this software may need tons of revamping to make it work. The main thing that tips me off to that is the fact of how each of them turn on. This may be minor, but it does signify in my mind a bit of different circuitry (hall effect vs push button).
Like I said though, this is just theory and though. I'm looking forward to finding out though.
