Status DalSoRi OPL4 board

I used my makita and drill with a low speed
Frist I draw with a marker where the hole must be Made then screw the two party's together
Then I used a small drill to 3mm to make a fist hole then with a 4,5mm and ended with a 7 mm
maybe I was to carefull but I didn't want to break the cartrigde
It worked Great for me without damaging the cartridge

@Retrofan : DalSoRi arrived at home, tested and working fine

@marcoo & Grauw : thanks for your tips An assembled cartridge could be better for me.

I drilled my hole today too. I went up to 8mm, still not big enough for some plugs on some cables, but it would do. I might just buy a suitable one that has a narrow body above the pin. The plastic is quite soft so, I actually used my hand and drill bits for the first few mm until my drill battery charged. overall, the whole product, packaging and purchasing process was great, thank you all!

I did end with a monster hole, so the whole plug from my speakers fits in :]. This was not ment to be that big at first but the drill did slip a little and the first hole was a bit off. Anyway every kind of plug should now fit . Testet and working great. Love the small size. Thankyou to all who made it possible
