Control Circuity
Even with many advanced features such as Digital
Convergence Circuitry, PIP/POP, V-Chip Program
Blocking and the Diagnostic Mode, the Control cir-
cuitry is not overly complex. An overview of the
circuit is shown above. A 100 pin surface mount
µPC is the heart of the Control circuitry. Primary
inputs come from either the front keyboard or the
