I saw and reviewed WOZ some time ago and identified a few things that i thought would be issues to operators. i told whoever would listen (next to no one.) But turns out, those chicken have come home to roost.
Now understand that WOZ is an incredible machine. But frankly it's just not designed to be operated. Sorry Jack, but it's not. I mean it's the coolest pinball ever (aside from the theme of a chick trying to get red shoes), but there are things that should have been designed better.
First and foremost are the connectors. There are a zillion of them on WOZ, which in theory is good. But in reality, they are MUCH too small. I've been telling anyone that would listen for years that anything other than a .156" locking molex or a "mini-fit" style plug (Gottlieb system3) is inadequate for pinball playfields. The connector pins are too small, the wires too thin (to fit the too small pins), and the wires and/or pins break or crack at the solder joints. Williams demonstrated this with some system11 drop targets and the magnetic ball sensor on Twilight zone. You damn well would think people would learn from this mistake, but apparently that's not the case. (Stern for that matter makes this mistake too, so it's not just Jack.) WOZ has connectors on the EOS flipper switches, probably a bad idea too...
Light boards. They are still serial. Meaning if it fails upstream, ALL lights downstream don't work. I thought they were addressing this, but apparently not.
Speaking of light boards, they have non-replaceable fuses soldered to the board. REALLY? and to boot, they are either 2 amp or 15 amp. Seems like a wide range, and seems rather random. But a non-replaceable fuse??
Tim at the PHoF has been experiencing these problems in spades. He can't keep WOZ running due to these small but important issues. He's modifying the light boards with a replaceable 3AG style fuse and fuse holder. Seems silly that he has to do this. And all the small connectors are failing too.
I realize that this probably isn't an issue with home use games, but for a solid operator, these things should have been addressed! Hopefully Jack is more respondent than Stern (who doesn't listen to anyone, and continues to decrease the quality of their hardware at every corner, even when only one penny is involved) when it comes to issues such as these.
