VIDEO HARDWARE NOTES:

- The cool thing about this hardware is the use of microcode, which is like having a little graphics coprocessor around to do the hard stuff. The operations that can be performed by this bit of circuitry include pixel plotting, line drawing, sprite drawing, and data transfer, all with optional collision detection. In addition, data can be uploaded into the $2000-$21FF address range and then "executed" as mini subroutines. Commands to the microcode are written to the command register at $C102, followed by whatever parameters are needed. Parameters are stored in registers. The microcode is actually a big state machine, driven by the 4 PROMs at 19B,19C,19D and 19E.
