For the most part, all solderless breadboards are alike. 5 or 6 contacts spaced 0.1" connected across, a gap (typically 0.3" wide), and 5 or 6 contacts more, and repeated x times down the other length (0.1" from each other). Some have rails on either end that are connected most of the way through.
My question is, does a breadboard without the center gap exist? I know there are ones with a wider gap (0.6"), but I have not found any without the gap. Do they have a different name?
My goal is simply being able to plug in a standard Dual In Line header without needing an adaptor, or modifying the breadboard (cutting out the middle, or cutting a contact set in half)

Idea: Get some stripboard, and solder rows of 0.1" spaced female headers to it to create a facsimile of a breadboard.
You can cut across traces to disconnect adjacent headers from each other that are spaced only 0.1" apart, thereby creating the receptacle you want.
