One file, `iic.defs` is included by all of the other source files. This has entry points, origins, and various RAM locations defined in it for use by the other source code.
### Test Scenarios
#### Basic Functional Tests
1. With no bootable ProDOS RAMdisk, boot the system from power off or ctrl-oa-reset.
- Expected: The system boots the same as an unmodified ROM 4.
2. With a bootable ProDOS RAMdisk containing ProDOS, boot the system from power off or ctrl-oa-reset.
- Expected: The system boots from RAM disk, an inverse R may appear on line 24 of the display.
3. Power on the system with the ca key pressed or use ctrl-ca-reset.
- Expected: The menu is displayed.
4. RAM disk recovery:
1. Battery-backed RAM present with bootable ProDOS RAM disk: Power off the machine and leave it for 1 hr. Power on.
- Expected: The system boots from RAM disk.
2. Battery-backed RAM present with bootable ProDOS RAM disk: Erase main RAM from 0400 up (e.g. in monitor: `400:A0` then `401<400.BFFEM`) and press ctrl-oa-reset.
- Expected: The system boots from RAM disk.
#### Menu Item Functional Tests
All cases: When any menu option is selected, the "ROM 4X MM/DD/YY" message is displayed on the bottom of the screen.
0. Monitor
- Expected: We are dropped into the monitor immediately.
1. Reboot
- Expected: System boots as normal.
2. Zero RAM Card and Reboot
- Expected: Reboot if no card RAM present. Otherwise, counter appears in upper left corner and card RAM is cleared.
3. Diagnostics
- Expected: System enters built-in diagnostics as if ctrl-oa-ca-reset was pressed.
4. RAM Card Diagnostics
- Expected: System enters RAM card diagnostics if card RAM present, then/or (no mem) drops to monitor when exited by failure or user escape key.
5. Boot SmartPort
- Expected: The system boots from a SmartPort device, skipping the RAM card and 5.25 floppy drives.
6. Boot Internal 5.25
- Expected: The system boots from the internal 5.25 drive, skipping the RAM card. The system may proceed to the SmartPort if no disk is found.
7. Boot External 5.25
- Expected: The system boots from the external 5.25 drive, skipping the RAM card. The system may proceed to the SmartPort if no disk is found.
# The Whole Story
The Apple II Plus was the first computer my family owned. It's what I learned to program on. We spent hours at the keyboard typing in programs from magazines, and eventually I learned to modify them and write my own. As technology progressed, I switched to PCs like almost everyone else and largely forgot about the Apple II after the 90s. But, I held on to most of the stuff I'd acquired for it, much of which became cheap in the years after Apple discontinued the product line.
