Improvements in Data Selection Circuit for visual representation of the data from a personal computer.Consistent with the data of Ram are read simultaneously Screen of the graphical representation (12) and The Ram representation of text (13) and are represented by means of a Circuit of color television (21, 23) at a Scan rate of CRT Image: There are elements of. Choice of Data; for output is switched to the two types (1213) Data Display by a Unit Point (R, G, b), which comprise a RAM (22) has output Data from The Ram of the graphical representation (12) as input direction (15) and the data entered from the microcomputer (11) by means of a Data bus (14) As input data.
