These OpCodes are listed in Table 2. The name of the OpCode appears in the left hand column. The following two columns represent the actual binary information contained in the 20 bit data stream. Some commands have limits on which command can follow them. These limits are shown in the "Allowable Follow on Commands” column. The last column summarizes each command. Combinations of OpCodes can be used to accommodate almost any memory management scheme.
