You can use these to build your own NES!
 
(I also have the UA6527 UA6528 ntsc sets available, these were used in the dendy micro nes famicom system clones. Identical to Ricoh's except the audio pins are reversed and the composite video amplification is different apparently.)
 
I plug each set in and check they work, take a photo next to the order number. There is no guarantee against damage during installation! Please don't email me saying "I can't get this to work etc etc" this will be a bad connection or installation damage. This is 2nd hand hardware there is no money back guarantee!
