(...) "Mobile Robots" is a nice book. I really liked it. Is there anybody who knows more about "Build Your Own Robot!" by Karl Lunt? It's available on-line but I haven't found any reviews for it yet. Does anybody have it? Is it any good? -- Eric (24 years ago, 10-Apr-00, to lugnet.robotics.handyboard)

those two things together strongly suggest that your crystal isn't running. any chance you can get a scope or logic probe to verify this -- measure the E clock output of the 'hc11 (pin 5). also, check that you've properly installed a 2.2 megaohm (...)
