I got a 33/68 without using Wikipedia, including #1 on the list - The Magnavox Odyssey....Did it in around 6 minutes before I ran out of consoles + got too tired of re-naming 3 systems.
However, I got a few more thanks to improper spelling:
Coleco Telstar (thought it was Telestar)
Turbografix-16
Phillips CD-I (thought CDI was one word)
Nokia N-Gage
Back from the dead, I'm afraid.
