      Nice hint. Next video on µCurrent prototype? 😉

    • Why not do a part one and part two to real go more into detail. Also why couldn’t you bypass the internal power supply and use bench ones to see if the computer would boot up?

      “superior to the Amiga” might create some disagreement. 😉

      Those oscillators actually are strange because they’re using Japan’s modification of the NTSC standard. North America uses a 3.58MHz colorburst. Japan uses 4.43MHz. If you divide the first one, you end up with 15.700… an odd multiple, but one that isn’t as funny as if you tried to divide it by 3.58.

      My husband, he had this terrible dysfunction where he couldn’t get it up, I felt really insecure because of it and it nearly destroyed our marriage, but after using the information we found ( http://tinyurl.CoM/getItUp12 ) we are finally able to make love again and not only that but it’s better then ever.
