Engineering Changes to CRC65 rev0 for VGA65 prototype
Cuts
- Cut Address A1 in two places to isolate connections to CPLD
- Cut Address A5 in two places to isolate connections to CPLD
- Cut RDY in two places to isolate connections to CPLD
- Remove 100pF C3
Jumpers
- Connect A1 (6502-10) to CPLD-2
- Connect RDY (6502-2) to R6
- Connect HSync (CF-25) to IRQ (6502-4)
- CF-25 is HSync (HD15-13)
- CF-23 is VGA video out (HD15-1,2,3 through 330ohm resistors)
- CF-37 is VSync (HD15-14)
