Two different PCBs were found with same components, albeit some from different producers.
The coin acceptor is driven by a MCU (unknown type).
The dumped version (Mini Guay VD) uses plastic displays with light bulbs, but there's a different
one (undumped) called "Mini Guay VR" (VR stands for "Version Rodillos") or just "Mini Guay" with
reels instead, with an additional PCB for reels control (8031 + 2764 EPROM).
