Need help identifying these boards.

The top two with blue connector, we built for CP-500 and CP-650. One is the remote and the smaller is the "cell" input board. Also works for CP-45. The rest?

The bottom two on the right are by DTS...the ribbon cable adapts a JM21 type cable to a DB25 system...with the subwoofer line being jumped between Le and S/W (hence the one wire looping out and back in). The one on the bottom left I've never seen before but it seems cool...I guess it is a Component Engineering board for testing. Hook it up to a DB25 put your test meter or speaker on the test terminals and use the rotary switch to select the channel. No doubt it would speed up setting DTS to 300mV.

The bottom left looks virtually identical to a board I have from DTS (not CE), except my board has 6 discreet test points plus a ground, no rotary switch. After reading Steve's description, and comparing to the board that I have, it makes sense that is what it is for.
