This is, indeed, a Ham-M control box. It can be used with the Ham  
series of rotators, since they are all pretty much identical  
electrically.

CATS has a history page about the CDE series of rotators - http://www.rotor-doc.com/history.html

You should be able to find a schematic for both the HAM-M and Ham-II  
rotators on the BAMA archive.
