Looks like I am probably coming to the show. I'd be helping out around the Project Pinball booth.
I just put a new Pascal/FLIPPP board in my Joker Poker and I have a full set of working System 1 boards along with the new style interconnect cable that I removed. Don't ask me why I bought the new board when the old ones are all working fine. Includes an early/old Ni-Wumpf MPU recently updated to the latest 3.54 code, original driver board and original power supply along with the new interconnect cable. Boards appear to have no burns or hacks. Picture below before removeal. $175 obo.
