# No Slot Clock ProDOS Driver Adapted from `NS.CLOCK.SYSTEM` (by "CAP"), with these changes: * Fixes a typo * Removes beeps * Is less chatty so you can have multiple clock drivers, e.g. if you use the same hard disk image across different hardware configurations * Uses file I/O rather than block I/O for chaining * Does not hard-code driver file name ## Other Utilities These `BRUN`able files are also built: * [SET.DATETIME](set.datetime.s) sets the No Slot Clock date/time. `NS.CLOCK.SETUP` is for use with [SETUP.SYSTEM](../../setup/README.md).
