Exam 1 Answers Errata

There were a couple of problems with the scanned-in version of the exam solutions. Here's some fixes:

• Page 4 - Problem 6: "No" => "Not".
• Page 5 - Problem 7: The File 1 symbol table should also include "a" and "c".
• Page 6 - Section II: The word in the parentheses is "instructions".
• Page 11 - Datapath: The top mux should be labeled "PC Mux".
