Notes

PCB is marked: "U G" on component side
PCB is marked: "Lato Saldature" on solder side ("Lato Saldature" is the Italian for "Solders Side")
All roms images were dumped from TMS2708JL EPROMs found on an unknown manufacturer's (but surely italian) Head On bootleg.
PCB had no silkscreen nor any solder mask on both sides.
No CPU was found but the socket pinout is compatible with Z80 pinout.
Both proms image were dumped from SN74S288 ICs at positions A3 and A4, assuming the lower left corner IC position of the board is A1 when having the component side up and the interface connector at the bottom.
