This is a strange little problem, and I'm trying to figure out the best way to do it. I have a little prototype board with a 40-pin socket soldered into it (originally there was an 18F452 plugged into it). For an project that I am doing, I want to plug a 28-pin dsPIC30F3013 into that socket. Obviously some pins will go unused, but that is OK. One way, which seems pretty awful, would be to just hard-wire a 28-pin socket to the appropriate pins of the 40-pin socket. Seems like there should be a more elegant way, though. Ideally, I'd like to do it in a manner which will allow me to go back to plugging the 18F452 in when I'm done.
