The SNES has several of what appear to be pull-up resistors:
| Resistors | |
|---|---|
| Name | Notes |
| 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 |
| R77, R78, R79, R80, R81, and R82 | near the diode arrays |
| R92 | on the /IRQ line going into the 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 |
| 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) |
