    Recently the monitor of our old lonely 3600 died and we won't spend
    the deutsch-marks symbolics demands for a repair. But we still need
    the color system (8bit) of the 3600.
    So my idea was: why not put the color system (color-controler,
    color-mem, color-paddle) in our 3640? There are tow free slots,
    (marked CC and CM = color-controler and color-mem??) and the only

You should be able to move the color boards over to the 3640 with no
problem.  The only issue is that you will need a two-slot baby
backplane.  If I remember correctly, the 3600s had backplane wiring in
them and did not use a baby backplane.

You are correct in your interpretation of CC and CM.  The baby backplane
will span the same two slots, but on the *other* side of the backplane, 
where the smaller size cards go.
