Abstract
PURPOSE: To make it possible to modify microprograms from a video terminal by storing microprograms in a randam access memory (RAM).
CONSTITUTION: The modification address of microprogram (MP)-storage RAM5, sent out from keyboard 17 of the video terminal, is stored in screen editing RAM6 by way of write buffer 4 of the terminal controller. With LP-strage RAM read indication key on keyboard 17 depressed next, the modification address is read out from RAM6, and a fixed amount of MPs to be modified equivalent to the modification address are read out from RAM5, and stored in screen buffer 15 before being displayed 19. After modifying MP by keyboard 17 over the observation of display details, an operator depresses the key of indicating the transfer to RAM15 to read out MPs from screen buffer 15, so that they will be transferred to RAM5 and stored in the previous modification address.
