I can distinguish between the real hardware and the Jrok board within one second.
Not saying it's not a good board, quite the opposite, I use his Williams board and love it. It's a great alternative and I would never run a PC in a cab, I don't want to wait for 20 seconds for such a machine to boot, give bootscreens etc.
JROK's board run original processors. It's not emulation. Only the sound is emulation.
I am still waiting for his Mylstar board, even though I have a real Q*bert board-set now.
The Berzerk board-set is like that for a couple of reasons:
1) Stern was (IS !) a pinball manufacturer and they were "used to" a set-up like this
2) Berzerk went through several fases. First they used another processor, which proved to be buggy so they had to redesign it to another one.
3) Berzerk started out as a B/W game. When the fist color games started to appear they decided to "add" color, and "add it" they did with another extra board.
It is 7 boards, 1 is the PSU board, 1 is the filter board, 1 is the main board, 1 the sound board, 1 voice board, and 2 others I forgot the exact function off

You can "complain" about such a complicated set-up but it has two brilliant advantages: the board draws-out from the FRONT so it's a breeze to work on them !
AND if something is defective you can go swapping boards instead of having to fix something on that board. This way I was able to make three working board-sets for "the three stooges" a long time ago

I LOOOOOOOOOOVE Berzerk, it's easily my favorite game after my SW. It's strange cause usually I prefer the games that I have a link to from the past. Although I played Berzerk on the Atari XL a lot (best home conversion) I never played it (or even saw it) in the arcades. But it is such a brilliant game....
Synoym9: Yes busy 5 day job, another big hobby taking up a lot of time and a little family.....and yes I am happy about it. I have to stay relaxed about it....I am pretty stoked to finish the Ms.Pac soon after Eurocade.
Then it's........Q*bert time !!!!
