That's hard to quantify because there are a number of distinct processes. First, all circuit boards are manufactured on the automated surface mount line. Then, the few through-hole components are added. The boards are tested on a component level test rig, which shows up any assembly mistakes.

Next, the players are assembled on a manual production line, loaded with software, and tested for full functionality on another automated rig.

The final test process alone takes about 5 minutes per player - around 90 hours for a batch of 1000.
