A fellow retro enthusiast picked up a whole bunch of stuff recently, and in it were some Spectravideo bits and pieces. I am looking for this type of gear, so took it off his hands. Unfortunately no computers or games themselves, but a 903 Tape drive, RF modulator, 318 user manual, advertising brochure, warranty card and a whole bunch of users group publications.
After a quick search I found this guy http://www.electricadventures.net/ has a bunch of scans available of these publications on his website. I have some issues which he does not have scans of, so I will scan and send them to him. Preservation is a good thing.
Now I really want to find some actual Spectravideo units! If you are located in Australia (especially Tasmania), I want to buy this from you!
