Hi,
I have a bunch of these PCB Prototype Boards, green, double sided, tinned, with long large flat connectors on two of the four sides. I was wondering if they plugged into some kind of standard connector ?
I have attached an image of one (original image from Welcome sabernetics.com - BlueHost.com )
I was looking at some of the edge connectors, and they seem to "kinda" match but then again, they do not go all the way to the end.
If not for edge connectors, do anyone know what they are for?
Perhaps you could solder headers or wires directly to them.
.
Just seems strange, as they are without holes and at the edge of only two sides of the board.
I have used dual row headers, solder the pins on both sides ( PCB goes in between)
There are edge connectors, but those aren't them - there's nothing connected to them, and if you soldered a wire to them, you couldn't plug them into a connector, because the solder would get in the way.
I was extremely disappointed in those protoboards. I had some better (imo) protoboard made like the picture in my avatar - check out the tindie link in my sig to buy some.

GREAT idea !
Do you know of any easily accessible (aka cheap) prototype boards that will allow for edge connectors ?

Nope. Why do you want edge connectors anyway? LarryD's suggestion was spot on - use pin headers and "Dupont" connectors.
{Original "Vero" boards were available with single-sided edge connectors. I built my first microcomputer ("SC/MP") using them with a Vero "motherboard" using 0.1" sockets to match - Veroboard naturally makes a backplane. No, hang on - I just used the end of the Veroboard as the edge connector. 
}
Those are strange boards; if they were meant as "edge connectors", then they were poorly designed, as I would expect such to being narrower and longer (and connected in some manner to the first row of holes).
Probably they were meant to just act as spots to solder/tack wires to from the rest of the design.
Personally, I would go with LarryD's suggestion to use the dual-row pin headers (male or female - whichever is best for your application).
Indeed - perhaps that is what those pads were meant for...

I am working on a larger project. I am currently using 40 pin IDE cables as connectors, but would like a "real" passive BUS, that looks like a computer, not a squid (as 4-5 boards do now, connected with 40 pin IDE cables) - therefore edge connectors. These prototype boards can be bought in all sizes and shapes.
Problem with LarryD's suggestion is, that double pin headers do not fit perfectly. They are off by 1.0 - 1.5 mm. That has to be soldered away. Also, I was looking for edge connectors.

I did not realize you were demanding to have something fit perfectly.
If you know what you want, design a PCB to your requirements rather than creating a Frankenstein.
