| + | ROM 4X and 5X are enhanced firmwares for the Apple %%//%%c and Apple IIc Plus. | ||
| + | |||
| + | Main features: | ||
| + | |||
| + | * Initializes memory expansion card without erasing it if it already contains a boot sector. This is intended for battery-backed memory expansions made by [[http://www.a2heaven.com/webshop/index.php?rt=product/category&path=73|A2Heaven]]. | ||
| + | * Boot menu via <key>CTRL+CLOSED-APPLE+RESET</key> or <key>CTRL+OPTION+RESET</key>. | ||
| + | * Allows dropping into the monitor immediately. | ||
| + | * Allows clearing memory expansion card. | ||
| + | * Allows launching diagnostics. | ||
| + | * Allows selecting boot device. | ||
| + | * 4X: Allows booting external 5.25 drive if disk supports it. | ||
| + | * 5X: Replaces accelerator firmware. | ||
| + | * <key>CTRL+ESC+RESET</key> toggles accelerator speed and persists across ordinary resets. | ||
| + | * <key>CTRL+TAB+RESET</key> brings up a menu that lets you set accelerator state and some option. | ||
| + | |||
| + | In development: | ||
| + | |||
| + | * 4X - available in pre-release: Configure ordinary boot to behave as if one of the menu options was selected. | ||
| + | * 5X - in the works: additionally, set accelerator state (disable/speed/paddle delay/speaker delay). | ||
