Z80-MBC3 initial boot after assembly. Usage of the buttons and boot options.

After you have assembled the Z80-MBC3, or bought a ready to run version, here you see the methods to hook it to a PC, configure the terminal settings, and watch the sign on messages and selection of boot options. The Z80-MBC3 saves the choosen boot method and automatically loads it after pressing the RESET button on the board. To change the boot method and call the boot menu again, the USER button must be held down before you press the RESET button. Here I only show how to adjust the Real Time Clock, get into the BASIC interpreter and thereafter switch to QP/M as the disk operating system. The SD card contains images of all the available virtual disk drives. CP/M and QP/M both have 16 disks with 8 MB capacity.
