2x 8 DIP switches banks

Notes

main PCB is marked: "3002A" on component side
ROMs PCB is marked: "3002B" on component side
ROMs are identical to "Darwin 4078" already in MAME, PROMs are not!

---

update 20181207 from Osso: The PROM has bitrot problem on 1 bit. For the rest it is identical to what's already in MAME.
