AAAAAAHHHHHHHH, MAD PLANETS MAD PLANETS MAD PLANETS !!!!
Looks like a converted cab though....
On those years most of the cabs where assembled in here in Italy (cheaper than import from USA) even under license. SIDAM or SIPEM produced many games on same cab, changing just marquee and bezel ( like Zaccaria do).
If you see, even joystick is totally different from the Gottlieb one, but all is absolutely original and not converted.
DigDug in one of the exceptions with the dedicated graphics but totally different from the USA version.
Even motherboard is produced by Sidam under license, is totally different but use all the Namco custom Chips.
Same story for the Mad Planets pcb
