Bob:

On the old Moog modulars, were the panels sanded, clear anodized,
then silkscreened black with a reverse image?

Thanks,

In 1964 and 1965 we made a few modules with 'Metalfoto' material.
Metalfoto is anodized aluminum with a photosensitive material embedded right
in the anodizing, and you 'print' the image exposing the material to
ultraviolet light and then immersing it in some photographic chemicals.
After that we used a meterial called 'Fotofoil" for modular panels.  Fotofoil
is anodized aluminum in which the anodizing is dyed black and then covered
with a photosensitive resist.  You expose the resist through a photographic
film, then wash away the unexposed portions.  This leaves the unexposed
portions uncovered and the exposed portions covered by the resist.  Then you
put the whole panel in lye, which etches away the uncovered portions and gives 
you the panel design in in natural aluminum.  That's how all Moog modules were
made after 1965.
