# ROMX ProDOS Clock Driver

Original source c/o Jeff Mazur.
Add ROMX RTC driver, c/o Jeff Mazur. This is a modified version of the ROMX Real-Time Clock driver. The changes include: * Converting the source to ca65. * Integrating with the driver installer framework. * Adapting the driver to not modify page 2 beyond $220. The ROMX RTC firmware writes bytes to $2B0, and the the original driver placed temp code at $250. This can conflict with ProDOS applications that use page 2, so the driver was reworked to save/restore anything at at $2B0. Other changes: * Add a util/ source dir, and cricket/date, quit.system and pause.system there. * Pull the "print current date" logic out of clock drivers into driver preamble. 2021-10-05 19:58:31 -07:00			`# ROMX ProDOS Clock Driver`
