penguin42@TechConnectify Is the speed of the 'score'/5 motor carefully tuned? - everything else on the relay system is 'locked' and waits for an 'ok' from the thing being incremented.
@penguin42 Not that carefully - though Bally and Williams tended to run their motors more slowly than Gottlieb did, at least in the 1970's.
Gottlieb score motors are a wildly different beast, though. They are so much harder to wrap your head around (and I can show you one in the next video! but it's not attached to a working machine)
@TechConnectify It's pretty interesting; I guess you've got to get the timing right so that you don't try and add the next 5th until you've completed the previous 5th carry propagation has happened (huh unless you can have multiple additions with their carries ongoing...); that's kind of the equivalent of clocked vs async circuit design; but...then you've got circuits for 'going past a score' - that's really tricky if that's looking at the score as it's being added. Oh, and nice sparking 🙂
@penguin42 The timing of the cams (which is all down to their spacing and alignment of the switch stacks) is much more critical than the speed of the motor.
You could really "overclock" the machine as fast as you like until you start exceeded the speed at which the springs can reset the solenoids and relays.
Weirdly I guess it's a similar problem to valve float in internal combustion engines!
