Question about the Nintendo VS board pinout

[Masterful Gaze]

I've been searching around the net for the Nintendo VS pinouts so I can put together a harness. Most of the places i've seen have this listed as the pinout:

This Video Game Pinout Data Sheet Was Typed In By Chris McBride.
                     EMail:  mcbride@cs.arizona.edu

                     -> VS. Unisystem Standard Connector <- 

Name Of Game: vs Super Mario Brothers
       I assume it also works in other vs. systems:
         vs. Duck Hunt, vs. Excitabike

Notes: This is for the Single Monitor upright systems.

Does anyone know what the M's and S's mean?

[Dav]

I don't know that I've ever actually seen it defined, but I always assumed it meant master/slave.

[Rocky]

Main and Slave

It refers to the 2 monitors / CP's for a dual system

[Kevin Mullins]

That applies if your board is labeled MDS...... which like they have already mentioned is a Dual Sytsem board for running two game at once on two monitors with two control panels. Two seperate locations for ROMS.

[Masterful Gaze]

Thats what I was thinking, but at the top it says

Notes: This is for the Single Monitor upright systems.

Typo I guess?

[Kevin Mullins]

It also says it's for Super Mario Brothers which is found on these dual system boards but only running on one bank of ROMs. You can run only one game to one monitor and control panel. You do not need to actually have both games going.

Is this the board you have? (MDS)

I have a complete .vs manual with schematics , etc, I just want make sure it's the MDS information you need. Which is what those ".vs kits" used.

[Masterful Gaze]

Thanks for the info, helps me out alot and yeah it's the MDS version.
