Video RAM.
The Video RAM is organized as 8-row arrays
(21 x 7 bits each, Figure 11). The first location of each row
array contains the attribute for that row. Row attributes in-
clude programmable character color, row background col-
or and control for background off/on. The next 20 bytes
contain row character data. Each character byte contains
the ASCII code in order to select one of the 96 displayable
characters. LDE or LDEI instructions are required to ac-
cess the Video RAM (Figure 11).
