Address locations 0x04 through 0x6E store the VID, PID, Release Number and String
Descriptors if they are enabled by the mask bits in location 0x03. The data are stored sequen-
tially as described below:
Initial Check Byte
This check byte is located immediately after the last VID, PID or stings. It is computed as the
truncated sum of Mask1 and all the string length specified.
Keyboard Matrix
The keyboard matrix is 144 bytes. If specified, its check byte is located in address 0x6F while
the matrix itself is located from address 0x70 - 0xFF.
0x70 = Col 0, Row 0
0x71 = Col 0, Row 1
.......
0x78 = Col 1, Row 0
0x79 = Col 1, Row 1
.....
0xF8 = Col 17, Row 0
0xF9 = Col 17, Row 1
.....
0xFF = Col 17, Row 7
