MaciNap is a small PCB which shuts down the analog board and slows down PWM fans when the screen is blanked.
Screensavers prevent CRT burn-in, but won't save your analog board or flyback transformer.
MaciNap monitors the video signal and shuts down the analog board once the display has been blank for about three seconds. When resuming from sleep mode, the video signal is suppressed until the sweep circuitry stabilizes, to avoid bright lines on the CRT. Power consumption is typically reduced by half during sleep mode.
A single amber LED on the board indicates status:
MaciNap generates two fan PWM signals which have a duty cycle of 100% when video is active. During sleep mode, they're reduced to 50% and 75% duty cycle, reducing airflow and noise.
The PCB intercepts the red wire on the PSU/AB harness (12V sweep). The video signal is tapped from the back of the analog board with a black/white twisted wire pair. The yellow and black pair shown here powers the Noctua PWM fan. The fan's blue PWM wire is soldered to the MED pad for speed reduction:
Basic through-hole soldering skills are required for installation.
Any screensaver which completely blanks the screen will activate MaciNap's sleep mode.
Basic Black is a lightweight screensaver recommended for System 6 and 7.
Available on Tindie as a 2-pack.

A single amber LED on the board indicates status:
- Bright - Video is active and the analog board is powered.
- Two flashes - Video signal is dark and analog board is shut down.
- Dim - CRT protect: analog board is starting with video signal suppressed.
