Hop on the bus...

Wiring of the 25 way way D-sub connector; this is the bus which will go between different 19 inch rack units. This finishes off the Control Unit (except for production of an actual front panel to replace the 3 mm foam board mock up...)

By the way, heatshrink cable markers indispensable in keeping some sort of order in the wiring...

Next tasks: production of a batch of four integrator / sum boards (to go in Integrator Unit) and production of the Coefficient Attenuators Unit (mainly pots and switches)...(each of these units will be on the bus).
