Hinton Music Lab module closeup - ML1890 Switch

Some close up pictures of the Hinton Music Lab modular's ML1890 Switch. This module is pretty special having a logic buss at the rear for the 8 switches which I can interface directly to my MANIAC & Arthur prototype systems. This makes them particularly handy for being modulated by Cellular Automata logic patterns. The ML1890 can switch both audio and control voltages and was built by Graham Hinton back in the mid 70's !  The inputs are duplicated to nuclear physics spec Lemo connectors which connect to the virtual earth inputs on the module, allowing input signals to be summed directly on the Pin Matrix module.

Here are some example recordings of the Hinton Music Lab in action :
