Notes
main PCB has no markings, but it's a 100% copy of an original Atari board, with some components missing: no audio amplifier, no volume trimmer, no switches.
On top of it there is a custom made PCB, with a few TTLs, all of them with markings removed.
Custom PCB is marked: "TBM 57914006 S G PERSICETO BO" on component side.
Custom PCB has a 22x2 edge connector, with hand soldered wire going to various locations on main PCB.
The manufacturer TBM was founded in 1978 just to produce this game.
