Analogue Haven has adapter boards available that can be used to connect Bob
William's AS modules to the A-100 bus (I know it as we manufacture these
adapters as a special design for AH).

The AS uses 16-pin IC connectors (like integrated circuits) with this pinout

GND GND (side with the IC marker)
GND GND
+12V +12V
+12V +12V
+5V +5V
+5V +5V
-12V -12V
-12V -12V

So it's totally different from the A-100 bus which uses not only a different
type of connectors but has also a different sequence of the pin assignment:

GATE GATE
CV CV
+5V +5V
+12V +12V
GND GND
GND GND
GND GND
-12V -12V (colored wire of the ribbon cable)
