2.1.3 General flow chart for Initial Program Loading
Initial Program Loading is normally accomplished by the above simple operation.
Individual operations needed to perform Initial Program Loading in special cases (for example,
when loading from a cassette tape file with the floppy disk unit connected to the MZ-80B; or when
loading from a drive other than drive No. 1) and measures to prevent errors are described later.
FIGURE 2.6 depicts the general flow chart for Initial Program Loading. Execution of Initial Pro-
gram Loading normally progresses as indicated by the solid line; however, manual operations may be
required depending upon conditions at the branchpoints.
