摘要： For each row of characters to be displayed the characters and associated attribute information (underline, flashing, etc.) are transferred to buffers 161-164 on bus 191 from the terminal memory. The characters are then converted by a character generator 253 and shift registers 271 to a VIDEO signal for a monitor 180 during the raster lines pertaining to the row, counted off by a raster counter 254. The characters are stored as strings in the memory in correct character order but arbitrary row order. Associated row designators include the address of the first character to be displayed in the row, a pointer address to the next designator the number of the first raster line of the row to be displayed and the number of lines to be displayed. At the end of the last line of each row the newly pointed to row designator is transferred to registers which address the first character to be transferred to the buffers 161-164. Horizontal scrolling is effected simply by changing the first character addresses in the designators. Smooth vertical scrolling is effected by progressively incrementing first raster line number and decrementing the number of lines to be displayed (or vice versa).

摘要翻译：对于要显示的每行字符，字符和相关联的属性信息（下划线，闪烁等）从终端存储器传送到总线191上的缓冲器161-164。然后，字符发生器253和移位寄存器271转换为用于监视器180的VIDEO信号，该视频信号是在由栅格计数器254计数的与行相关的栅格行期间。字符作为字符串存储在存储器中是正确的字符顺序但是任意行顺序。相关行指示符包括要在行中显示的第一个字符的地址，下一个指示符的指针地址，要显示的行的第一个光栅线的数量和要显示的行数。在每一行的最后一行的末尾，新指向的行指示符被转移到寄存器，该寄存器将要传送到缓冲器161-164的第一个字符。水平滚动可以通过改变指示符中的第一个字符地址来实现。平滑的垂直滚动是通过逐行递增第一个光栅行数并递减要显示的行数（反之亦然）来实现的。

摘要： Rows of characters are displayed on a raster scan CRT by the dot matrix technique. The dot matrices are determined by a DOT CLOCK signal and, in order to allow different size characters to be displayed in the same frame, dot frequency signals are derived from a master clock 501 by division by two (flip-flop 504) and division by three (flip-flops 502, 503) respectively. A signal SC135 which can change state at the beginning of the first line of each row selects between the two frequencies via gates 507 and 508. Two signals (PIPE CLOCK and PIPE ENABLE) are derived from the selected DOT CLOCK by counters 510 and 511 which divide by 10 or 9 as selected by a signal SEL 135 selecting different character field widths.

摘要翻译：字符行通过点阵技术显示在光栅扫描CRT上。点阵由DOT CLOCK信号确定，为了允许在同一帧中显示不同大小的字符，点频信号通过除以2（触发器504）从主时钟501导出并被除以三个（触发器502,503）。可以改变状态的信号SC135可以通过门507和508在两个频率之间进行选择。两个信号（PIPE CLOCK和PIPE ENABLE）通过计数器510和511从所选择的DOT时钟导出，通过选择不同字符字段宽度的信号SEL 135选择10或9。
