[sdiy] Roland M16C / M64C memory module - Connectors

[rsdio at audiobanshee.com]

The photo of the cart shows the tell-tale dual scratch marks that standard card-edge sockets leave on the PCB traces. That's hardly definitive, but it does look like the socket should be compatible with a rigid PCB.

I'd recommend using calipers to measure the opening in the socket, and not get too close to that limit. Looks like the plastic allows for only so much, and the spring-loaded contacts press inward from there.

I'd like to see the receiving connector, too, because if it isn't spring-loaded then forcing an incompressible PCB into the connector is not going to last very long. Wouldn't want to ruin a JX8P just to make a cheap cart!
