Namco System 22 connector identification

[tiff_lee]

I'm trying to identify the connector types used on the Namco system 22 mainboard & I/O board so I can make a test harness. Having looked through the Ridge Racer/RR2/RR schematics none of them ID the connectors like Sega does in their schematics.

On the main board there is:
9 pin
50 pin

I/O board
20 pin
30 pin
3 pin
8 pin (JST NH?)

i've attached some stock pictures i got off the net but can get better ones if need be, or maybe someone will already know... cheers

The white one is molex 3191 series:

The 20/30/50 are JST RA (https://www.jst.co.uk/productSeries.php?pid=89) and are a pain to find. You will probably have more luck finding a ribbon cable that fits.

Or you need to fiddle in Digikey nice search system to find a connector that might fit. for exemple for 50 pins

Excellent cheers mate.

Such a pain how there is so many different connectors used on arcade hardware. Just looking at a another Namco board and it has 4 different connector types and there is only 8 headers on the thing ><
