xdaliclock is supplied on a disk image that is compatible with most Color Computer emulators. To use this clock, you must transfer the disk image to a physical floppy disk or transfer it to a system such as DriveWire or the CoCo SDC. Please refer to the appropriate system manual for inserting the game disk or image into your system.
