The picture looks like the insides of an SJ Plug. Like I said, nothing
fancy required! The good thing about Econet is that you can cobble
practically anything together to get a useable network. I remember
my first Econet which was made with wire taken from the cord off an
old mouse, with 1-inch strips of paper clip soldered onto the ends and
then pushed into the DIN socket of the Beeb!
I still have the scar on my finger where the scissors slipped whilst
cutting up the paper clips....

..that sounds like how mine are made - mounted inside a DIN plug!
Well, it was once ... there's a picture of it with my DIY socket boxes
