Thanks for the response!
I definitely have to research further into those topics soon.
I completely "ignored" gbox, so this could take me a long time. I definitely think that is the feasible thing to try.
Multicam, i saw some pictures of 3 models. AHAB and NG look like they can "do stuff".
I also saw some pictures of homemade pcb, looks like an 74HCT014 (hex inverting schmitt trigger) and a 6 Mhz crystal should also be feasible.
Do you have any further advise on those topics?
I don't want to let the magic smoke escape yet, so my first research should probably be gbox.
again, very big THANK YOU.
