Four 8-bit video ALUs ：Explained in more detail as part of Advanced Instructions section
ALU Operations ：Conditional Code (CC) Bit in ASTAT
CC bit is used in several instructions
Action taken in the instruction depends on the value of CC
If cc jump here; //if cc = 1, jump to label “here”
If cc r3 = r0; // perform move if cc=1
CC bit value is based on a comparison of two registers, pointers or accumulators；CC bit can be moved to and from a data register or ASTAT bit；CC bit can be negated；
