The Joust on the left is a JROK FPGA multi Williams setup. (Look into it if you don't know.

Joust hanging on the wall is a custom build by myself that had the JROK in it, but now has a Pandora 10th anniversary board (5000+ games) and the Robotron is all original, but has a ram error at the moment that I needed to fix. Then a 96-in-1 Pacman kit on the cocktail. (plugs into a real board, not emulation). Next, mint Tempest in mostly working order. And lastly a skinny vertical cab with Pandora KOF 412-in-1 vertical games only board. And there is a 60-in-1 in the garage that I'll likely sell. Plus an Attack from Mars 1up pinball in the opposite corner.
