Running the Program

Mount the disk.d64 image into disk drive 8 of vice and load the program with LOAD"hello",8 or LOAD"hello",8,1 and run it with RUN or SYS 2061 or use the short cut:

x64sc -pal -autostart disk.d64  

You can also copy the content of the disk image onto a real disk or use a sd2iec device to test the program on real hardware.

Disassemble
