Pin Patch Matrix

via this auction
auction details:
"The possibilities are endless with these patch matrices. They are much smaller versions of those found on the VCS 3, Synthi, and Vostok synthesizers. I haven't been able to locate the manufacturer's name on theses guys.

They would be great for circuit bending the smaller synths and toys
or maybe you could mount all four in a square, cover that with a "master" face panel, and spread out the pin nputs to create a Synthi sized matrix and give yourself more finger room.

I have four of these in perfect shape.

Each matrix ships with 10 gold-plated pins."

Looks like a Ghielmetti patch matrix.
