core memory

Ok, to do anything with this board, I have to find 'card edge connectors'. (I think that's what they're called.)

There are 26 pads over a  span of 3". Note that I'm not counting the 2 on each end of those spans (because only one-quarter of them have wires, and they're separated a bit more than the rest). KIM that the board is double-sided (and, yes, the contacts are aligned directly opposite each other).

So, does anyone know where I can find such a creature?
