Post by: arcadefever on November 30, 2006, 09:21:56 pm

hello,

just build a jamma loom for my bombjack pcb, it work great...but the only probleme is, when i try the pcb on any of my vertical  cabs, the picture is upside down  ???

i look at the dip...but nothing about flipping the monitor  :( ..., i even tried on my astro, that is mount vertical, when ever i try a vertical game, it's ok , only bombjack is upside down ... any idea why ???

thanks

if the cocktail switch works then when the second player comes up it will reverse the pic and when you switch it off it won't,how often do you want to swap games out of this cab or have you got a multi jamma

You can always flip the monitor yoke wires, I have done that a few times

I play my BombJack PCB in my Time Pilot cabinet and the orientation is the same. Kangaroo is upside down, though.

The early classics didn't have a standard for which way to rotate the monitor to make it vertical. So..... you never know what you're going to get when you hook up an early 80's vertical game.

A lot of the games started adding a dip switch to change it by the mid to late 80's (called screen flip for most of them).

I added switches to my yoke wires on my Time Pilot (it's wired for Jamma). Now if I want to play a game it it boots up wrong, I just throw the switches on the monitor.

Hi.

I have some old-school PCBs that need the screen flipped, too.

Are there any instructions on how to add the switches for flipping the yoke?

Thanks :)

Bob Roberts has a nice write-up on the yoke wire flipping.  Instead of just flipping them. I used a DPDT switch to flip them.  I used one switch for horizontal and one for vertical.
