Hello all, There is a company called Small Parts Inc. located in Miami Lakes, FL. They have been a good source for me in the past for all kinds of random stuff.

Can you access variables declared in a binary progam from a different binay program? i.e. can "speeda" (pcode.asm) be accessed by xxxxxx.asm? Do you have to know the actual address where "speeda" is stored or can you just use "speeda" inside (...) (27 years ago, 16-Apr-97, to lugnet.robotics.handyboard)

To avoid that battery problem, I have mine plugged in about 20 hrs/day and the other 4 hrs the serial interface is plugged in.

The best answer would be to take the mAH of the battery, say X=1500 mAH. Find out the current drawn by the RAM say I=5mA. Divide X by I and you get the number of hours of battery life. This is ofcourse assuming that you have a fully charged battery (...) (27 years ago, 16-Apr-97, to lugnet.robotics.handyboard)
