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) |
