NFG Games + GameSX

Namco's Cyber Lead cabinet is a weird sort of thing, with heaps of functionality. So much functionality that most owners will probably never use a lot of it. Like the LED display at the top of the cab, or the cabinet's link function for two player games. And all of these neat toys come with a new connector and pinout.

For the most part, all the connectors in the cabinet are one of two types, both made by AMP. The data communications are mostly EI series, and everything else is Universal Mate n Lock.

The JVS CONV board converts the cab's internal JVS communications to JAMMA for use with older boards. It is self contained, with a single JAMMA connector handling all player inputs, unless you need the 6th button, which requires the kick harness. It does a bunch of other things as well, like create an s-video output, lower the JAMMA spec video to VGA levels, manage stereo/mono sound, and so on.

It's called the N48 Harness according to Namco docs, so this is the N48 Harness Connector. It handles extra player buttons, as well as extra speaker outputs from the PCB.

Pin	Function	Pin	Function
1	Speaker +	6	P1 Button 5
2	Speaker -	7	P2 Button 5
3	GND	8	P1 Button 6
4	P1 Button 4	9	P2 Button 6
5	P2 Button 4	10	GND

This board is used twice in the Cyber Lead cab, once behind the control panel and again beneath the LED display at the top of the cabinet. The boards are identical but the connectors and components on them are different, so they're not interchangeable.

Pretty standard stuff here. An EI-series 12-pin connector is used to connect all the signals from the PCB to the board. The pinout is the same for P1 and P2. The manual indicates a red connector is used for player 2.

Pin	Function	Pin	Function
1	Up	7	Button 2
2	Down	8	Button 3
3	Left	9	Button 4
4	Right	10	Button 5
5	Start	11	Button 6
6	Button 1	12	GND

While the manual indicates the default controller is a Seimitsu LS-56, the schematic (And many peoples' experience) suggests the actual stick was a somewhat rare LS-33 (or LS-33NA) with a pinout that doesn't match Seimitsu's normal connector.

The connector used for Sanwa and Seimitsu sticks is a JST NH-series 5-pin. The pinout for the LS-33 and the normal Seimitsu/Sanwa mechs are:

The specific order for the Seimitsu and Sanwa sticks is fiendishly complicated because it's wholly dependent on orientation. If you mount your stick with the connector facing down, the only pin you can rely on is ground, the rest will change based on that orientation. As a result, I can't claim this is totally accurate, though I believe it is. There's a decent chance the Sanwa and Seimitsu pinouts are in reverse order, but since the connector can simply be flipped, it hardly matters.

The Namco pinout is correct, based on a connector on the RIGHT side, if you're looking from the top of the control panel. If you're looking at it from below, it'll be on the left side (P1 stick connector towards center of panel, P2 towards edge).
