I didn't see any mention of it here and even so it wasn't until now that it's close to being ready. This is a one-stop solution to having all Cinematronics games able to run on a Cinematronics cab or an Asteroids Deluxe (or Asteroids). It should have options for all the Cinematronics games along with some cool variations like color Star Castle. It's being developed on this site -
You can contact them and let them know you're interested (if you're interested). No word yet on when and for how much but this could at least cover a bunch of vectors from one company (though a few have odd control panels so an all inclusive multi-cab might be too cumbersome). I'm looking forward to this since it would allow for less room needed to cover all the bases while also providing new, more reliable sources for those old games (vs. keeping old PCBs alive).
