Disassembly of Glen E. Bredon's RAM.DRV.SYSTEM for Apple II ProDOS

This was started before realizing what the origin of the RAM.SYSTEM found on a MouseDesk 2.0 disk image file was.

There is a more complete diassembly with commentary at:

Project Details

• The orig branch compiles to to match the original.
• The master branch has additions, including:
  • Chains to next .SYSTEM file in dir order (not hard coded)
  • Chains to next .SYSTEM file on non-block devices (e.g. file shares)

ram.drv.system's Issues

Chain to next .SYSTEM file

Currently, RAM.DRV.SYSTEM chains to a hardcoded file (or QUITs). This means recompiling or byte-editing the file to configure the install sequence.

Instead, it should follow the pattern used for NS.CLOCK.SYSTEM and chain to the next .SYSTEM file listed in the boot directory.
