[sdiy] Roland M16C / M64C memory module - Connectors

[MTG]

If memory serves it's 1.6mm.  I remember back in the day some PCB carts 
were tinned by hand to make the thickness work. There are some web pages 
where people have made new cartridges with varying degrees of success. 
It always comes down to this connector.

I've been hoping for years that somebody has some surplus connectors and 
just decides to dump them on the market. Yamaha and Kawai use similar 
versions. I think only the slot is in a different place.

If someone can recreate Curtis and SSM chips then you'd think this would 
be possible too.
