Images of the circuit boards of various SEGA consoles. Includes VA6, VA6.5, VA7 model 1s, VA0, VA1, VA1.8, VA2.3, model 2s, VA1, VA2 model 3, Nomad, early SMS, Sega CD model 2, and VA1 game gear. Might be useful!

Photos of the video output on various versions of the Genesis using RF, composite, and s-video.

Probably availavle elsewhere, but I'm mirroring it here too in case it goes down.

Same deal.
