[Coco] 6809 wafer on eBay

[Mark J. Blair]

By the way: Notice the ink dot marked near the center of each of the devices on the wafer. The ink dot means that device failed testing, and every one on the wafer is marked with a dot. In other words, the reason that wafer is intact on eBay rather than being diced up and in computers in attics and landfills all of the world, is that it's 100% scrap. The whole wafer was defective, so it wasn't worth cutting up into dice.
