There was a very undetcible component-side solder bridge between pins 2 and 3 of RP4. I might not know until tomorrow when I can get a replacement for RP4 (apparently I'm not very good at desoldering, and I didn't see the bridge at all until I (...)

Hi, Thanks for your reply. RP4 has the part # 88102G, and adjacent pairs of pins have resistance of 1k (ie, 4 discrete resistors). Ok, Tell me if this sounds really strange... R15 is installed, but tested at about 1k ohms, not 47k. I remove the (...) (22 years ago, 16-Jan-02, to lugnet.robotics.handyboard)

Sam, can you check the serial input circuit. if this is not correct, then the 6811 won't stay in boot mode. make sure RP4 is a 1Kx4 resistor pack (4 discrete resistors) and not a 1Kx7. also make sure R15 is installed. see (URL) . also, try putting (...)

Ok, RP4 was fine. I've put a logic tester "MODA" line on the chip (from what I can figure, this is this pin that gets the signal from the stop switch), and it is recieving a signal when I press the stop switch. I verified that the reset pin was (...) (22 years ago, 15-Jan-02, to lugnet.robotics.handyboard)
