Joshua Bell 7bbc96924b Add SETUP.SYSTEM and build .SETUP files 
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.

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.
