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)

Hi! I'm still can't get the chip to go into bootstrap mode. I've double checked I've got all the components installed in the correct direction, and inspected the entire board for shorts, and have found none! What can I do?? I'll try resoldering the (...)

(...) You attach the triacs to the handyboard, or is this just sequencing without using the HanyBoard? Either way I can get more information on how/what he did. BurningMan... gee who would have guessed :-) Sam (22 years ago, 11-Jan-02, to lugnet.robotics.handyboard)

Hi! I'm putting together my shiny new HanyBoard. I've got to the point where I'm testing the serial line/power led on the HanyBoard itself. The processor won't seem to go into bootstrap mode(ie, the green light won't go out, and attempts to download (...) (22 years ago, 11-Jan-02, to lugnet.robotics.handyboard)
