So, I have this project I have wanted to do for awhile, where I am going to make a giant "breadboard wall", by linking together many many breadboards and power rails and busses. Sadly, I have found that for the breadboards I currently have, they do not all play nicely when it comes to interconnecting.

What I would like are any recommendations for breadboards that can interconnect both horizontally and vertically. In addition, the cheapest option(bulk is ok too, since I'm sure I'll be buying many of them)would also be desirable.

I will probably have something in the ballpark of a horizontal power rail every 5ish breadboards vertically, a 16 wide vertical bus for every 3-6 breadboards, and just the generic middle section of a breadboard filling in the rest of the empty space.

Thanks for any help that can be offered!

Here are some I found in the first few minutes of searching:

The last one was from Banggood and may be the best bulk option. The rest have manufacturer and part number in the image name.

Some breadboards have mounting holes instead of tabs.

I have some that I acquired 40 years ago that have interlocking rails along all 4 edges. They don't seem to be available...

Some other options on eBay:

The last one is similar to the one I thought was no longer available.
