Can someone help identify this NES imitation?  All I know about it is:

1)  It is old, not a new knock-off.  Circa 1980s, no reference to Nintendo on it anywhere.
2) It has a tag on the bottom that reads "Entertainment Computer System Model: NS-80 Rating: DC10V 850mA Sale No. 030284 Made in Taiwan"  Sorry for the crappy image, camera would not focus.
3) It fits like a top loader, but is actually a front loader
4) Takes a standard NES power supply and plays normal NTSC 8 bit carts.
5) Has eject button on the top, slides toward the front where the cart is inserted (not pressed down toward the floor like a top loader)
6) It has two jacks in the back, one for "Adapter" (power supply) and the other for "RF Switch"
7)  It has three jacks on the right hand side labeled "Head Phone", "Audio" and "Video".
8) I've not seen another like it.

Is it worth anything on the collecting scene?  If not, I'll hang on to it to play the games I remember getting for Christmas as a kid.  If it is worth some money this post will likely have a sister post in seller's corner or it will go on ebay.  It is not mint, but it works fine.

Thanks.

Thanks, albailey.   It is very similar.  You can see the Power and Reset buttons are on the left on my unit, where they are on the right for the link provided.  Other than that it looks spot on.  If anyone has more info on it, I'm interested.

It is the mini-NES system. It was popular in
Daycare centers, across US and Canada. That is
all it is, a smaller version of the NES itself. Their
are many variants of this kind all over the place,
some being built in cost-effective nations.

You can run into it, by accident. Some where sold
along side regular NES models.
