Randy, Thanks for your help so far, but I have a few questions. How can I remove drivers to get more room. Where can I quickly get a copy of IC 3.1? And how much does it cost? -Joe (...) (27 years ago, 27-May-97, to lugnet.robotics.handyboard)

I have been having big problems with the programs that I have been writing for my handy board. I currently have around 1400 lines. I expect to have about 2000 when I'm done. I have many functions called throughout the program and recently have (...) (27 years ago, 27-May-97, to lugnet.robotics.handyboard)

(...) At some point, you may run out of memory on the Handyboard; however, it sounds like IC 2.8 is running out of the 640K DOS-limited memory. You might try removing drivers to get more room in the lower 640K. If you move up to IC 3.1, which is a (...) (27 years ago, 26-May-97, to lugnet.robotics.handyboard)

A very simple program which will exercise the motors in this configuration is listed. The first section will put a message on the LCD then wait until the sopt button is pressed. Once the stop button is sensed, it will turn on the motor in port 0. (...) (27 years ago, 26-May-97, to lugnet.robotics.handyboard)

also, joe... there are several programs you can run to get more conventional memory (640)... dos 6.0 to 6.22 comes with memmaker... run this a couple times, toy with the settings a bit to see what you can pull off... one of the settings may cause (...)

(...) Thanks, I stuck a pot in it's place and fiddled with it until I got 4.49k and it worked great. I came up with the 4.49k by taking 1/x*.0068 = 32.75. Where .0068 is the cap, and 32.75 was my desired frequency. So x was determined to be 4.49 (...) (27 years ago, 23-May-97, to lugnet.robotics.handyboard)

Hi Fred, I do not know exactly of your situation with the IR detector/emitter arrangement. I found that it sometimes picks up noise occassionally. I also found that with small resister in the range that you are using (330ohms), the range is too much (...) (27 years ago, 23-May-97, to lugnet.robotics.handyboard)

Fred, could you please reconfigure your mailer? I'm getting some very strange headers, and it upsets Eudora Pro's filtering.

Brett, Since I'm going through a couple of corporate LANs and WANs, it would be no easy task to reconfigure my mailer.
