This allows two boards to sit flat on a table top. Again allows you to connect two boards together, but with straight connectors. Get the singles even though they are more expensive. The duals are only .19 but are a straight vertical insertion. Jameco are showing a new product in their latest catalog, the 30 pin dual vertical Simm Socket.

Now, I need to find out the quality of this new product. Hi Guys, I agree with Bob that the Dual SimmSockets from Jameco are poor qualtity. DigiKey, Mouser, and all the surplus houses seem to have a good selection of the sockets. You want to get the ones with metal latches and make sure they are straight and not angled ones. One problem is that the qualtity seems to vary widely so its best to order a few to start with and more if they look good.
