    Default NES PPU question (NES-101 top loader)

    how hot, if at all hot should the RP2C02G-0 get in a top loader.

    i finally got one and its not working, i knew it wasn't working but to me it sounded like there was some feedback during games and some static on screen BUT...

    games wont boot at all, i get a random flicker of colors, rarely any pattern but nothing pertaining to the game at all and i notice when i tap around the area with the pot above the reset button it kinda changes a bit, i think i am causing it with the tapping but it could be that its flickering to different colors so rapidly it just looks like i am doing it. and the ppu gets HOT. burning hot and i have a high tolerance, change oil on cars after they have been running in the summer tolerance for touching hot objects HOT.

    cart is getting a good connection, it had some plastic chunks in the cart slot i got out and made sure the pins were ok, nothing too damaged, one was a bit bent out of the way but i was able to bend it back.

    i'm thinking dead PPU or dying but i thought i would double check before i went and yarded one from a broken toaster

    that was the price after shipping, and its in good shape, no chipping some pits on the plastic on one of the corners like it was dropped on a coarse surface (like cement or what evs) but clean. thought the posting on ebay said it had noise on screen during games but played games still....

    again still very clean, the cart connector was pretty crusty but I managed to get the shielding off of it and clean it up some and a bit o polish and there it be, lookin better.

    then came the post about the PPU, I noticed it was hot but what I didn't notice until I watched game techs video is how fast it got hot. it goes from zero to scalding in under 2 minutes. and then after watching his video about the ppu and it giving the same exact screen....

    it was simple really, if I had waited and diaged it a bit more and noticed how hot how fast the PPU got then it would have been a no brainer. but instead I lost all patience and asked dumb questions.

    I socketed the PPU because maybe, hopefully, in the near future i'll get a NES RGB kit from etim. maybe if I have any money left after PRGE
