Same PCB for Centipede cocktail and upright?

I assume Centipede uses the same PCB for the cocktail as it does for the upright and cabaret, but the dip switch options don't seem to indicate a setting for cocktail play. Are they different PCBs?
 
ray, i'm searching now and haven't come up with much. however, the technical manuals both give the same part number for the pcb's for both uprights and cocktails, so i would think they're the same, however i can't come up with any dip setting that switches between UR and table mode.
 
Thanks Jim. If the part numbers are the same, then there must be someway to tell the game to flip the screen for cocktail mode, but I just read through the Centipede manual and it said nothing about it.

I know there is an on-screen menu, but there doesn't seem to be anything in there about cocktail mode either. Very strange.
 
Missile command is a wire in the harness that is grounded for cocktail and not for the upright (possibly vice versa). I would think centipede would be the same or similar.
 
Ah, that's pretty cool. So it is the harness itself that tells the PCB to flip the screen between players or not. Can anyone confirm that this is the case for Centipede?
 
yep, stated already, but per brasington.org -

Game is in cocktail mode, how do I change this?
Centipede and Millipede do not have a cocktail DIP switch like some games do. Instead, Atari used a pin on the harness to determine upright versus cocktail mode. For millipede, this is pin 16. Millipede pin 16 should be left open (high) for upright, or grounded (low) for cocktail. This is backwards from how centipede does it. So if you are using some sort of centipede to millipede adapter or have rewired your harness, check that pin 16 is properly setup.

To assist, the multipede testmode will display the text "UPRIGHT" or "COCKTAIL" to show you what the current mode of the game is.

Multipede does not change how upright versus cocktail is selected, it continues to be determined the same way the millipede hardware determines it.

If you are using the arcadeshop.com centi/milli adapter, please make note that for upright move you need to remove the cocktail/upright jumper on the adapter.
