OK, I haven't used this system in a while so I'm selling it. No, I'm not getting out of NEC hardware, I just don't need more than one Duo.
You get:
1 US Turbo Duo with original controller and power supply. The AV cable is a TZD replacement.
Riot Zone Super CD (aka: Tony Hawk's Riot Zone) complete.
It all works. I recently fixed the drive door (it always thought it was open). There are no audio, or CD access problems. This unit skips if you bump it (more so than my Duo R) but as long as you aren't banging into it, it plays perfectly. I'm the original owner (1992).
The thing that sort of devalues this unit is the huge Yuna 2 sticker placed on it. Its a really cool sticker, and it is applied with such mastery that it almost looks like a special PC Engine Duo: Yuna Edition, but its still a huge foil sticker that many people won't want. The foil is really thick. Its not like a regular foil sticker. This unit has been used quite a bit, so there are scuff marks on it, but no huge gouges or anything. Cosmetically its pretty nice.
I'll post pictures when I can tomorrow after work, but I'm looking to move this sucker in a hurry. If $140 seems fair to you, PM me. I'm flexible on this. I also have a copy of Darkwing Duck (loose, the manual is lost, there never was a jewel case for this title) that I will add for a very fair price if you are interested in one of the more obscure US titles.
PayPal required. I will ship internationally. PM me with questions.
UPDATE: Crap, I just remembered that this system is in fact packed way in bubble wrap, in a perfect mailing box, at a good friend's house...115 miles away, and I'm going out of state tomorrow so I won't have pics for probably close to two weeks. If you feel like buying it sight unseen, contact me. If you really want the pictures, then you'll have to wait a while and risk someone buying it blind.
I can say in all honesty, its not bad looking. Seriously.
UPDATE: Pics added:
