If you want to hack into the power and video signals on your SE or SE/30 for… reasons… then this is how you do it.

The J12 Breakout for SE & SE/30 by Ron’s Computer Videos presents solder connections for the main power busses and video signals. Power your machine off an arcade power supply, and route the video to an external option. Great for making a CatMac or other custom project.  This new revision adds screw terminals as a timesaving extra.

NOTE: Use 16 or 18 gauge leads when connecting your project to modern ATX power.
