| Ive checked the mailing list archives and i cant find a simple answer to the following question: Is it possible to run the HB at >2Mhz? That is, can I run a different version of the 6811 perhaps and get 8Mhz? What are the advantages/disadvantages? (...) (25 years ago, 22-Apr-99, to lugnet.robotics.handyboard)

Unfortunately it depends on so many variables that you'll just have to implement one system at a time, checking each thoroughly and modifying as you go. Make sure to go back and (...)

| Hi, in Katalogs, there are many capacitors with the same capacity value but different voltage and tolerance. My question is, which voltage should I choose: above the operating voltage of 12 V? Second, the tolerance the lower the value it has a (...) (25 years ago, 21-Apr-99, to lugnet.robotics.handyboard)
