The Institute of Sonology in Den Haag purchased two VCS-3 synths back in the seventees (1975) . Over the years lots of students used the synths for their compositions and that shows. They are used! Both of them are still fully operational and in one of the machines I embedded a OSC matrix.
Parallel to the analog physical matrix on the outside (where the small pins make connections between the onboard modules), the OSC matrix is mounted. Great thing is that it has exactly 16 inputs and 16 outputs – the exact fit of the OSC-matrix.
