# ROMX ProDOS Clock Driver

Original source c/o Jeff Mazur.

`ROMXRTC.SETUP` is for use with [SETUP.SYSTEM](../../setup/README.md).
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. 2021-10-06 02:58:31 +00:00			`# ROMX ProDOS Clock Driver`

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. Resolves #16 2024-01-31 05:16:32 +00:00
