10 Yard Fight has two 256x4 character palette PROMs, one 32x8 sprite
|
||||
palette PROM, one 256x4 sprite color lookup table PROM, and two 256x4
|
||||
radar palette PROMs.
|
||||
|
||||
I don't know for sure how the palette PROMs are connected to the RGB
|
||||
output, but it's probably something like this; note that RED and BLUE
|
||||
are swapped wrt the usual configuration.
|
||||
|
||||
bit 7 -- 220 ohm resistor -- RED
|
||||
-- 470 ohm resistor -- RED
|
||||
-- 220 ohm resistor -- GREEN
|
||||
-- 470 ohm resistor -- GREEN
|
||||
-- 1 kohm resistor -- GREEN
|
||||
-- 220 ohm resistor -- BLUE
|
||||
-- 470 ohm resistor -- BLUE
|
||||
bit 0 -- 1 kohm resistor -- BLUE
