GRiDMaster is a personal organizer application. It included a calendar, alarm clock, calculator, notes, to-do list, sophisticated (for 1984) rolodex with phone dialing capabilities, and other customizable functions. The disk here is for GRiD-OS. As such, you will need to format the floppy disk you want to use with the GRiD-OS disk formatting utility (Initialize Media) before writing to it in ImageDisk. In order to format a 720kB disk for GRiD-OS, you'll also need to use a newer version of Initialize Media.
