I’m buying some PCBs for my arcade cabinet on eBay.  I’m currently focusing on “parts”, “untested” and “junk” boards in hopes of honing my repair skills.

Buying games as “parts” is risky, and usually a bit of work.  It’s a chance for you to get something under market value.  You might wind up with something that works perfectly because the seller couldn’t actually test it.  It might have a fault that you may or mat not be able to fix, or you might get a box full of bricks.  I took a chance and found a reliable seller.  This is the first of many game boards I’ll receive from him.
