CDC transistor boards

[Chuck Guzis]

Were the brackets on the 1700 cordwood modules shorter than the 6000
series?  I've got a switch module here in a desk drawer--it's a
3-position switch labeled A O C and is illuminated with a couple of reed
relays on the PCB.   PCB size is the same as 6000, as is the connector,
but bracket is definitely shorter.  Top PCB is labeled E03A; bottom is E04A.

I never did discover what it belonged to.
