And, of course, way worse than that. I bought a 44PLCC breadboard adapter off ebay. It only has 40 pins. I assumed that it had dropped the last 4. However, it had actually dropped the middle pin of each side, which is to say pins 1, 12, 23 and 34. Pin 23 is right in the middle of all of the control pins. It is actually clock. So, lesson learned.
Its a good job I don't mind embarassing myself in public.
