-
- Convert the color PROMs into a more useable format.
-
- Swimmer has two 256x4 char/sprite palette PROMs and one 32x8 big sprite
- palette PROM.
- The palette PROMs are connected to the RGB output this way:
- (the 500 and 250 ohm resistors are made of 1 kohm resistors in parallel)
-
- bit 3 -- 250 ohm resistor -- BLUE
- -- 500 ohm resistor -- BLUE
- -- 250 ohm resistor -- GREEN

- -- 1 kohm resistor -- GREEN
- -- 250 ohm resistor -- RED
- -- 500 ohm resistor -- RED
- bit 0 -- 1 kohm resistor -- RED
-
- Additionally, the background color of the score panel is determined by
- these resistors:
-
- /--- tri-state -- 470 -- BLUE
- +5V -- 1kohm ------- tri-state -- 390 -- GREEN
- \--- tri-state -- 1000 -- RED
