Fader Module

Two fader modules are present in the prototype control board. They are identical boards with different GAL programming and jumper settings. Figure 71 shows the silkscreen/assembly layer for the fader board. Table 2 shows the bill of materials for a single fader board. Figures 72 and 73 show the top and bottom routing layers, respectively.
