    That’s the only brand for 27c4000 in dip 40. If I try other brands as a 27c400 I get the same error (actually it errors faster). Algorithm is not related to the speed of programming, but more like a preset for the data of Vccp, Vpp, tpwp etc.

    Try an alternative brand of the same type and see if that helps Also, Algorithm says "Rapid" if this is write speed, reduce it if at all possible

    Color doesn't matter, this guy is the same thing: digikey.com/product-detail/en/…471MPD/493-1043-ND/588784 You may really want to practice soldering on some other, broken boards, before going back to this.

    It may surprise you to know that these caps were blue when they were new. Not green. So they've either been replaced previously or become discoloured ;) Either way they're not original anymore so no need to feel guilty in any way
