2.1 Initial program loading
All MZ-80B system software is supported by cassette tape or diskette files.
When the power switch of the MZ-80B is turned on, the Initial Program Loader (a file reading pro-
gram mandatory for activation of system software) starts. The loader reads the system software from
cassette tape or diskette files and, upon completion of loading, transfers system control to the loaded
program.
This action takes place automatically the instant the power switch of the MZ-80B is turned on.
Accordingly, in order to activate system software stored in a cassette tape file, you must load the
cassette tape recorder with the corresponding cassette before turning on the MZ-80B; to activate sys-
tem software stored in a diskette file, the corresponding diskette must be placed in drive No. 1 of the
floppy disk unit connected to the MZ-80B before the power is turned on.
2.1.1 Activating system software contained in a cassette tape file
Load the cassette tape into the cassette tape recorder and energize the MZ-80B. See FIGURE 2.3.
