Suppose the memory cells at addresses 20 through 28 in the machine described in Appendix C contain the following bit patterns:
Address Contents
20 12
21 20
22 32
23 30
24 BO
25 21
26 20
27 CO
28 00
Assume that the machine starts with its pro-gram counter containing 20.
a. What bit patterns will be in registers 0, 1,and 2 when the machine halts?
b. What bit pattern will be in the memory cell at address 30 when the machine halts?
c. What bit pattern will be in the memory cell at address BO when the machine halts?
