Joshua Bell f2ea11fcde Add "jumbo" clock driver, an amalgamation of the others
This one driver pulls in the installers for each other clock driver,
and invokes each in turn:

* No-Slot Clock
* ROMX
* FujiNet
* DClock
* Cricket!

This requires adding `.ifndef JUMBO` guards in the other drivers for
when they pull in include files (symbols, macros, etc). The other
drivers are adjusted to return with carry clear on successful install,
failure otherwise.

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.
