A simple "off the top of my head" NES addition:

NES M82 player
NES/snes test unit
Korean Comboy (original liscensed)
Secam France unit
NES cutout console test unit
Sachen 72-pin console
Europe has 1/2 dozen vintage clones
Brazil has more than that (the mini NES is so cool)

There is more....and none of this is Famicom


There are so many things that play NES.....you will really have to cull your defintion of "machine" to get a list to fit your search.
