When I was 13 or 14, I had befriended the Sysop of a regional BBS who was gracious enough to offer me (and my Father) a tour of his workplace “where they made the C64”. Feeling like Charlie in Willy Wonka’s world, I was awed by the magic within this building. Computers and gear everywhere. Soldering and test stations and seemingly alien technology that my young mind had never imagined. But one thing that really stood out were the massive palleted piles of new C64 “bread loaves” arrayed around the floor; each with a numbered page on top with the count. Asked about this, our guide explained “All defective and awaiting test.” Thousands. Maybe tens of thousands.
