摘要：A microcomputer development system in which two jobs, such as a sourceprogram and an assembler program, can be run and monitored simultaneously. A CRTscreen (10) is split so as to display information from both processor A (16) and processorB (18). A keyboard (12) is provided with a switch that toggles one of the processors sothat the keyboard is assigned to that one processor to the exclusion of the otherprocessor. In this case, the processor to which the keyboard is attached is designated theforeground processor, and its output is displayed highlighted on the CRT. The otherprocessor is designated the background processor, and its information is displayed inreverse video to distinguish it from the foreground processor. At power-on reset time,processor A is designated the foreground processor and is assigned the keyboard. Aprinter (24) is always assigned to processor A. A disk controller (20) is shared by

processor A and processor B, regardless of which processor is assigned to the keyboard.Information (flags) are passed back and forth between each processor and a

CRT/keyboard controller (14) in order to provide information to control access to fileson the floppy disk (22).
