This is the standard line printer that all 70xx systems have. | |
For WRS read next 24 words and fill print buffer. | |
Row 9, 8, 7, 6, 5, 4, 3, 2, 1, 10, 11, 12 | |
For RDS read rows 9, 8, 7, 6, 5, 4, 3, 2, 1, | |
Echo 8|4 | |
read row 10 | |
Echo 8|3 | |
read row 11 | |
Echo 9 | |
read row 12 | |
Echo 8, 7, 6, 5, 4, 3, 2, 1 | |
