My cable looks very much like your Minolta cable. I had to modify mine slightly to get it to work and it fits and works very well now. If you turn the cable over the black plastic side, you will see three ribs; two outer ribs and one thicker center rib. Take a X-acto knife or very sharp razor and carefully trim down the three ribs flush with the rest of the connector.

The plastic side should be face up and the metal side face down when you plug it in.  I took pictures of mine but I can't figure out how to include them in this post without a URL of them.
