The FAQ is linked from the main HB web page under the title "the Handy Board FAQ", or directly at: (URL) pcode source is at ftp://cher.media.mit...dist.tar.Z and also (URL) should fix that last link, because you'd never find it unless you knew (...)

| Fred, I have FTP'ed pcode-2.81.dist.tar.Z from cher (thanks for getting it back!) within it were the files foo.s19, pcode_rw.s19, lobo.asm, pcode.asm, and some makefiles.. Cool, but the files required for compiling IC 2.81 that I can't find are (...) (29 years ago, 1-Jun-96, to lugnet.robotics.handyboard)

|
| Well, I didn't get far without running into a bug. In the interface/charger serial circuit, I get 17 volts at pin 2 and I get 0 volts on pin 6. The MAX232 chip is oriented to the right, and all the capacitors have their negative stripes on the left (...) (29 years ago, 2-Jun-96, to lugnet.robotics.handyboard)

|
| (...) which pin were you using as ground reference? Maybe redo your test using pin 15 of the Maxim as ground. First check the Maxim is getting good power and ground (pin 15 is ground, pin 16 is +5). Then re-check the voltages on pin 2 (should be +9 (...)

| | | | | Re: Help debugging.
|
| Okay - thanks - you were right - I mis-read the ground location and used pin 7 of the MAX232 instead of using pin 7 of J9. The chip is getting 5 volt range, but the negative voltages are in the mid-8 range - is this something to worry about? thanks (...) (29 years ago, 2-Jun-96, to lugnet.robotics.handyboard)

| (...) No, mid-8's are fine. -F (29 years ago, 2-Jun-96, to lugnet.robotics.handyboard)

|
| HI, Can anyone tell me where to get some good motors that are more powerfull than the LEGO 9V motor but can be implemented into the LEGO's? I want to use the LEGO kit with the suspension, front and rear wheel steering and drive, and 4 speed shifting (...) (29 years ago, 3-Jun-96, to lugnet.robotics.handyboard)
| | | | | Yup, it works.
|
| Well after much delay, I've finally got my first HandyBoard up and running. (I've got another one in parts, but that is a different story) I can confirm that HBDL.exe does *NOT* work on my 133Mhz Pentium under Windows '95. It does work on my 486/33 (...)
