Abstract

The Link Test System (LTS) and the Multi-Simulator Control Unit (MSCU) are driven by several diskettes. A method is provided for changing the codes of these diskettes, without re-writing the diskettes, in the following procedure. (Image Omitted) When the Link Procedure Language Operating System (LPL/OS) is loaded and controls the processing environment, the LPL procedures are executed to check the diskette level in the order seen in Fig. 1. Because the MSCUs are set up for cells 0 and 1 on the first and cells 2 and 3 on the second, a Universal Controller Model 5 (UC.5) diskette is checked along with the first cell on each MSCU. When cell zero (0) of a quadrant is initialized in the LPL/OS bring up, as in Fig. 1, the program $DSKUC51 will be executed to check and update the UC.5 number one (1) diskette, if necessary.
