Prototype Easel program cards

I've been playing around with a few different configurations for the easel patch card.
Its is wonderful way to extend the capabilities of an already incredible instrument.

This is my first version using IC sockets to build the breadboard.

The circuit on the red breadboard is a very simple comparator.

The red breadboard can be removed. It plugs into the IC sockets if more development
space is needed.
This is my second version of the Easel dev board using headers rather than IC scokets.
I found it much cleaner and easier to work on.

A larger breadboard can be added if needed. And the patch cables have resistors embeded into them like the EMS synthi' patch pins.
