Tired of keeping a lead acid battery happy?
Get rid of the battery entirely with this. For wall-tethered usage only. Currently this does not offer a PRAM retention mechanism.
Only for use on Mac Portables which have had their capacitors replaced, and all related motherboard corrosion, fluid leakage, and damage fully repaired.
Neither JCMOne LLC nor Tech by Androda, LLC are liable or responsible for irresponsible installations (installing in systems without replacing the capacitors) or the effects of capacitor leakage on your Portable.

This is a “plug and play” VGA adapter for the Macintosh Portable.
Simply plug into your Portable’s display output port, connect to a VGA monitor, and you will get a 640×480 resolution output of the Portable’s 640×400 internal display. Black bars are added to the top and bottom for centering purposes.
The green LED on the Pico stick blinks after every frame of video is captured. It’s expected for that to steadily flicker.
Important Notes:
* Please only connect or disconnect this adapter when the Portable is turned off
* DO NOT use VGA extender cables for the connection to the Portable. This will short out your Portable and cause damage!
* Keep all conductive materials away from the male connector which plugs into the Portable – there’s a pin here which is always connected directly to battery voltage
Works for both the M5120 and M5126 (original and Backlit Portables).

This is a reverse-engineered replacement for the Hybrid Module in the Macintosh Portable (non-backlit version). This design has been tested on the tester / downstream board described here, in two of my M5120 Macintosh Portables, and on some community member M5120s for functionality.
Please run through the steps on this page to see if your Portable has the expected resistance and voltage measurements. If any of the surrounding traces or hardware has been damaged, a replacement hybrid may do more harm than good.
After installation, take care to watch the voltage on Q16’s middle pin (this is the system’s main 5v rail). If this spikes above about 5.3 volts, there can be trouble. Also watch the A/D line voltage (top left pin of the hybrid with reference to the product image). This should not go above 5v, ever.
