The on/off switch is inside the cabinet on the board with the transformer/fuses. Why? No idea 
I actually expected that to be so since I do remember I saw a switch there. Fine with me, I never use the "external" switches on my cabs anyway...I got central switches in my game room 
So I can move the ugly one from mine they hacked in 
Yes we need pictures of -everything- Synonym9....we are picture horny guys and .....mine is pretty damn hacked. It even has two monitor chassis inside !
I hope yours is in (more) original condition so I can use them as a guid for my restoration when I start that as soon as I become a pensioner.....

you get ANY information you want/need. I am sure that my Cab is totally stock condition as there are only 3 hacked games and you recognize them on the gambling-related squared buttons.
No matter if it was
Atari Asteroids
Stern´s Berzerk
or Zaccaria Astro Wars
, they always used that squared buttons.
I think they have got lots of that Novomatic Star-Line-cabinets, so they stopped hacking dedicated cabinets. Also they started in the gambling-business....so it looks like they did not care for the arcade games anylonger.
My e-mail is hannes.slanec@gmail.com and you find me by Hannes Slanec on Facebook.
drop me a line for what ever you want to see and I will deliver. Images, inside-vidoes....you name it - I make it.
The only thing is: It is at my friends Thomas garage and will stay there until I have picked every single game from the vendor up to the EM-machines and the Hang-On Bike....but after that my time is yours!
