Ah, the good ol' TG-16. My first system. (My older brothers had Intellivision, Colecovision, etc., but this was mine.) A great system. Still have mine, and a good number of games, but I'm not willing to part with them yet. I remember getting the CD drive that came in a box that rivals the Rock Band / Guitar Hero boxes of today, and all for what was essentially a portable CD player. The thing cost my parents, like, $400 (and lots of prodding from me)!! I have an import card. The thing sticks out about five inches from the cartridge slot. Many years back I got a TurboDuo off of eBay. Also came with a CD-R of Dracula X (and a few other games). I still have the original cardboard boxes (even the styrofoam inserts) of 98% of my games. And a plastic TG-16 (and I think 'Splatterhouse') labeled bag with all the ads and pictures of Turbo games. Some TG-16 shoelaces. And this really cool 2' x 3' posterboard of the TG-16 logo (both sides). I have a good handful of TG-16 only magazines (TurboForce, TurboZone, I think). I was a real fanboy (and anal retentive), that is until the games started to trickle out, then 'Sonic' came out, and 'Strider'. So I moved onto the true 16-BIT games and got a Genesis and SNES.
Recommended titles: 'Bonk' games, 'Blazing Lasers', 'Legendary Axe' games, 'Devil's Crush' (an amazing title and still playable today), 'Ninja Spirit', 'Ys' games, 'Valis' games, 'Exile' games. And the 'Military Madness' games (although I could never get into them). Plenty of clunkers as well. And stay away from the edutainment and FMV games. (Although there was this dinosaur encyclopedia that came out that I recall enjoying; totally out of date now, scientifically.)
Sorry to see TZD go bad.
Good luck with your search.
