From message #92158 (Jan. 4, 2014):
"Here's a set of photos I made of the console opened up.http://www.mediafire.com/download/f3oxgmb3wma9ubd/Supervision_8000_Opened.zip
It's a rather odd mess of wires inside, and I wasn't able to get a great view of both sides of the PCB. I'm not sure that would be possible without desoldering some of the wires, and I didn't trust myself to be able to put it back together again. I could identify some of the components, though--NEC D78C (Z80 family CPU, 3.58 MHz according to that website), AY-3-8910 sound chip, S68047P video chip, and NEC D8255C I/O chip."
I have scanned the carts and instructions. I need to take some photos of the system box, then I can upload everything I have.
I found a low-res picture of the PCB on this site:http://www.ne.jp/asahi/cvs/odyssey/videogames/sv8000/setframe.html
Click "System" on the bottom of the page.
I've never tried to hook it up. The pictures that are out there leave me a little confused about the colors. For example, the pictures on this page show Othello as white on blue:http://www.videogameconsolelibrary.com/pg70-super_vision.htm#page=games
This video looks to me like yellow on black:https://www.youtube.com/watch?v=QCo24GLyff4
