List of pull-up resistors
From SnesLab
The SNES has several of what appear to be pull-up resistors:
- R77, R78, R79, R80, R81, and R82, near the diode arrays
- R92, on the /IRQ line going into ito S-CPU
- R97, on the EXPAND line going into the Cartridge Slot
- R47, on the /MUTE line, near Q13
- R49, on the MUTE line, connected to Q13's collector
- R17, connected to the internal emitter/base of the blue Darlington pair
- R19, connected in series with R18 to the external emitter of the blue Darlington pair
- R12, connected to the internal emitter/base of the green Darlington pair
- R14, connected in series with R13 to the external emitter of the green Darlington pair
- R7, connected to the internal emitter/base of the red Darlington pair
- R9, connected in series with R8 to the external emitter of the red Darlington pair
- R21, connected in series with C8 to the video encoder (blue line)
- R16, connected in series with C7 to the video encoder (green line)
- R11, connected in series with C6 to the video encoder (red line)
