The programmer works great, by the way. But this kind of misses the point. Take up hypercard, modify the Francis Deck program: why venture farther into that tangled woodland as twilight sets in? The object is to advance the robot project, not to regress to making the tools to advance the project. I've already been burned by spending hundreds of hours on a robot design, only to have the whole thing go down the drain ( mechanical design, electronics, PIC code ) because my supplier of surplus stepper driven actuators went out of business. NO MAS! Ditto on trying to trick MacPIC into handling the new parts. John Zeissig To see the 'bot -- http://www.piclist.com#nomail Going offline?
