I think that boards in the lower cabinet is a great idea. EM's have had most of the hardware in the lower cabinet since the 30's. It is nothing new. Using history as a guide, if a location has a line up of games next to each other and you need to access the boards in the head, then you need a trolley or you can drag the machine forward to access the head. If the boards are in the lower cabinet (like an EM), then you lift the playfield and away you go.
Regardless, while games are on location, boards are rarely repaired. They are swapped over with a working board. No-one does board repairs on-site. Swap them over and return to base for repairs (unless the operator is unprofessional and likes to hack the boards while in the game).
If the standard for JJP is to access the boards via the lower cabinet, then I assume that doing a software update etc would be as simple as opening a coin door, and sticking in your USB.
P2K and the issues with the fan - I can't see that as being relevant because Pinballs were only designed to last 5-10 years MAXIMUM. I wonder if anyone still owns their Computer they bought 10 years ago ?
As I've stated before, I am not a buyer due to the theme, but I think that with JJP taking time to make sure everything is 100% instills confidence for buyers. Ironic that Stern rushed out AC/DC in anticipation of WOZ, and there were many problems. I don't see JJP having these problems. Should also be VERY interesting to see if the next Stern title has the same pricing as AC/DC - or will that be another "rush job" to hurt potential WOZ customers ?
I love the competition !
