       @TechConnectify Is it weird I often wonder with old contraptions like these how much energy the bulbs use and if using LEDs would cut a significant amount of power draw from the unit?

       @SHODAN swapping in LEDs is pretty common depending on the era of the game!

       @ben @SHODAN I could go on quite the rant about this...I had to remove LEDs from Theatre of Magic because they drive me nuts. Games from its era drive the lamps in a matrix, pulsing half of lamps with the positive AC cycle and the other half with the negative cycle. This dramatically saves on wiring.LEDs make that painfully visible, and it's even worse when the game does dimming effects (which it does all the time). Plus, the LEDs saved about 50 watts on a machine that uses 200 just to be on

       @ben @SHODAN The thing is, the lamps in those games are long-life lamps. They were meant to be in arcades powered on for 16 hours a day (and maybe even 24/7). But, they darken with age and should be replaced perhaps yearly.For so many reasons, LED swaps on games from that era just drive me up the wall. I want it to look like it did from the factory!

       @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!
