This may be what is meant.
I have seen something like this in Maplins. It is like a science kit. It is a plastic board with holes in for school kids to do electronic experiments with. the components plug/slot into the pegbaord and wires are connected at the back. i assume the components are on some kind of block with pins to fit into the pegboard.
i hope my description is making sense, but probably not.

The other thing he might mean is a Frequency peg board, like what some clubs use to keep tabs of who is on what freq. using coloured clothes pegs
