Pete, It seems to me that a simple double pole double throw relay could be used to select one or the other module. That way you wouldn't need to tie up any other IC/OC pins. You fire one unit, get the return, then switch the relay and fire the other (...) (26 years ago, 19-Oct-99, to lugnet.robotics.handyboard)

(...) Another guess - again pure speculation - is tha having an external adapter option made certification more difficult in one of the non-U.S. markets. I believe 1.5, aside from being an update for U.S., is also going to become the (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

Yes, they left it alone... The 1.5 RCX ROM has the same version number as the 1.0 RCX ROM. The firmware file shipped on the 1.5 CD is identical to the 1.0 firmware. Dave Baum (...) (26 years ago, 20-Oct-99, to lugnet.robotics)

The optimization was intentional (and quite a lot of work, actually). I know it breaks with multiple tasks, but I was more concerned with keeping the variable pool from being cluttered with temporaries. With only 32 vars to use, its quite easy to (...)

I got this error: Compiler error! 47 extra bytes left on board stack and I read in the technical manuel that all compiler errors must be fixed before I can download a file to the board.

The Scout (from the Robotics Discovery System) doesn't have a power connector either. It is quite possible that the decision to remove the power connector from Mindstorms products was made during the development of the Scout. There was only a single (...)

(...) I appreciate this -- that's what the "Not Quite" is all about. As long as you explain things well, I think this kind of compromise is the right way. (26 years ago, 20-Oct-99, to lugnet.robotics.rcx.nqc)
