ROM 5X by MG
DO NOT EVEN TRY THIS YET :-)
Warning: This has not been tested on an emulator or a real Apple IIc Plus.
This is a patch for the Apple IIc Plus firmware that tries to recover a battery-backed RAM disk upon cold start. Because of the limited space in the Apple IIc ROM. it does not have the complete feature set of ROM 4X for the (non-Plus) //c.
Upon cold start, the patch checks for a potentially bootable RAM disk and restores the appropriate screen holes to prevent it from being destroyed and to enable boot. If a RAMdisk is recovered, a flashing "R" will appear in the lower left corner of the screen.
To prevent the check and recovery, power on the machine with the Option key held down. A flashing "O" will appear in the lower left corner of the screen and the system will boot without checking for or recovering any RAM disk.
