Quoted from woody24:
Hmm. Very tempting to get an Asteroids for $75, buy the 12 in 1 board and deck from Arcade1up. Cheaper than buying the actual 12 in 1. Would be cool to have a dedicated trackball and spinner.
I didn't realize they were selling parts separately. I just checked, though, and the 12 in 1 control decks page doesn't seem to provide a link to purchase. Maybe they're out of stock.
Assuming monitor rotation was the same as your starting cab, I'd imagine converting to another game simply involves getting the respective PCB and control deck. I would also bet it's not too difficult to rotate the monitor if needed.
Not sure what the 12 in 1 control deck costs, but I priced out pcb, control deck and deck protector for centipede and came to about $70 total in the cart.
Given that I have the space, it would be more cost effective if I can get a $75 Centipede cab.
