This board was recently retired from CISL in Vancouver. It is shown here as received. More digging is needed to find out whether it saw service on 650 AM, or CKZZ on FM. As Red Robinson remarked, it could have been on the AM side, because CISL did broadcast in AM stereo for some time. Also, it is sporting the CISL decals. It appears to be a great design - no motherboard, just a ribbon-cable buss for all the input modules. The faders are in the audio path, but all audio switching and control logic is solid state. There is a digital clock and a digital timer.
Just as with the Auditronics we have, this board suffered the "cut-cables" syndrome. Yet it did come with the manual. Power-supply cables have been re-made - some audio cables have been brought to a jackfield. The meters light up, and tones can be routed to all the outputs. There are still lots of cables to be re-terminated.
