The ECL and EECL chips are located on  A22 (arming board), A19 + A20
(interpolator boards), A18, A17 (count chain assembly) A8 (reference
buffer), A21 (multiplier assembly).
The interpolator boards are more or less directly in line with the
ducted airflow from the fan as are  the reference buffer and frequency
multiplier boards.
A22 which has most of the ECL and EECL logic is mounted at right angles
to the initial ducted fan airflow which impinges on its rear surface.
