This is an alternate approach proposed by Sean Nolan in 1987 which allows placing the driver files in a subdirectory of the root volume to avoid clutter and file ordering issues. Only a SETUP.SYSTEM file is needed at the top level, and the drivers go into a SETUPS/ directory. All drivers here (except QUIT.SYSTEM and SETUP.SYSTEM itself) have alternate forms built into the /DRIVERS/SETUPS/ directory as XYZ.SETUP instead of XYZ.SYSTEM. If you choose to use SETUP.SYSTEM, place these .SETUP files in your SETUPS/ directory. The naming doesn't matter - any SYS or BIN file can be used - but this convention makes distribution easier. These .SETUP files do **NOT** chain to the next file - that's handled by SETUP.SYSTEM itself. Resolves #16

# Applied Engineering DClock — ProDOS Clock Driver
|
|
|
|
This is based on a disassembly of the Applied Engineering driver for the DClock real time clock add on for the Apple IIc.
|
|
|
|
> NOTE: Currently untested!
|
|
|
|
Like other drivers here, this one will:
|
|
|
|
* Conditionally install, only if a DClock is detected.
|
|
* Only attempts detection if there is not already a clock driver.
|
|
* Only attempts detection if the system is a an Apple IIc
|
|
* If detected, installs into ProDOS directly, following Technical Reference Manual requirements.
|
|
* Chains to the next `.SYSTEM` file in the directory.
|
|
|
|
`DCLOCK.SETUP` is for use with [SETUP.SYSTEM](../../setup/README.md).
