Want an insanely easy way to gain access to the video signals on the J12 connector on your Macintosh Classic or Classic II logic board? Look no further.

The J12 Passthrough for Classic and Classic II by Ron’s Computer Videos has you covered! Just plug it into your logic board, and then plug your power supply connector on top. All signals are presented on the IDC 10 connector header.

NOTE: You MUST remove the battery on the Classic II in order to install this unit.
