Bit-Pattern Codes
The following table illustrates the bit pattern for each of the 128 TRS-80
characters. The remaining 128 codes represent special graphics and space
compression characters, as described later.
See Notes.
To use the table:
Combine the most significant and least significant
bit-patterns for a given character. For example, the character Q is
represented by the pattern: 1010001 (decimal 81).
