You (gattameini) definitely should *not* use more than one timer
function (when_to_run := when_to_run + 1.0; delay until when_to_run;),
for when the next marble is to enter the top tray.

IRL there will be a finite delay for the mechanism to click through any
carries that may be needed, but I very much doubt you're required to
simulate that.


BTW, people, did you notice how I trimmed the quoted part of this so
that it only contains the bit I'm actually replying to? You seem to be
Google Groups users, so you probably don't notice what a complete pig's
ear GG makes of quoting!!!
