Table 9 shows the contents of the CRT display RAM. For example, to display 1 character position (the left edge) in block 1, write the character code in address 060016 and write the color register No. to the low-order 2 bits (bits 0 and 1) in address 068016. The color register No. to be written here is one of the 4 color regis- ters in which the color to be displayed is set in advance. For details on color registers, refer to (5) Color Registers. The structure of the CRT display RAM is shown in Figure 53.
