The part of the PPU that generates the video signal (immediately to the right of the NMI and CLK pins) appears to consist of a very long resistor between VCC and GND with taps at various points, and one of them (closest to VCC) is a switchable pulldown to GND (no doubt for color emphasis). The logic itself can select 12 different voltage levels (00/10/20/30, 0D/1D/2D/3D, synch, colorburst L/H, and GND), and they appear to correspond to 10 distinct voltage levels - one of the duplicates is at the highest voltage (likely 20/30), and the other one is the 3rd-lowest [non-GND] voltage (not sure which one). --Quietust 17:59, 28 September 2011 (UTC)
- With the help of ChipSim, I've traced down exactly what the 12 voltage levels correspond to - Synch (GND), Colorburst L, Color 0D, Color xE/xF and Color 1D, Colorburst H, Color 2D, Color 00, Color 10, color 3D, Color 20 and Color 30 ("and" == two signals which select the same actual voltage). --Quietust 11:17, 29 October 2012 (MDT)
Absolute Video Signal Timing
Some tests with Visual2C02 managed to confirm all of the contents of the Scanline Timing table, plus one more interesting bit of information: the offset. Specifically, the "active" region begins at cycle 4, which is when the PPU is just finishing the attribute byte fetch for the 3rd tile in the scanline (the first 2 are fetched at the end of the previous scanline). --Quietust 08:50, 1 November 2012 (MDT)
- But during which cycles is sync output? We need that too to align the NES picture center relative to the NTSC standard picture center (see Overscan). --Tepples 09:41, 1 November 2012 (MDT)
Michael Zimmerman's hedge fund
Venture capitalists reduce the danger associated with endeavor committing by means of having a collection of younger corporations in an business account. Many times they are going to co-invest along with different expert investment capital corporations. Also, many business alliance can handle many resources in unison. For many years, venture capitalists get nurtured the particular expansion connected with Our country's higher technology along with entrepreneurial towns producing significant career design, fiscal development as well as intercontinental competition. Corporations for example Digital camera Products Firm, Apple company, Government Exhibit, Compaq, Sunshine Microsystems, Intel, Ms in addition to Genentech are generally renowned degrees of corporations of which been given capital raising first inside their growth. "Carried interest" is the time period accustomed to signify the income separated of earnings on the common companion. This is actually the standard partners' payment to carry your supervision accountability as well as all the responsibility along with pertaining to giving this necessary know-how to be able to effectively handle this purchase. You will find as many variants of the income break up the two in the dimensions along with just how it's computed and gathered because you'll find companies.
