Apple ][+

Known issues:
Requires full keyboard emulation. At startup, full keyboard emulation mode is enabled by
default. Whilst in full keyboard emulation mode, some key associated functionality may be
disabled (like the ESC key for EXIT). The keyboard emulation mode is toggled using the
scroll_lock key.
Colors are incorrect (bug #475).

Usage:
Invoking the emulator with a floppy disk will boot from that disk. If booting without a
floppy, use the RESET key ("F3" in partial keyboard emulation) to get to APPLESOFT.
You can identify the APPLESOFT prompt as "]". Lines can be edited from APPLESOFT using the
arrow keys or using Escape, then "I" for up, "J" for left, "K" for right, and "M" for down.

History and Trivia:
The Apple ][+ is an incrementally improved Apple ][ that was released in 1979.
Most improvements centered around the ROM chip. It featured a floating point BASIC in ROM
called APPLESOFT instead of Integer BASIC. It also had an "autostart" capability which
caused the machine to boot automatically from attached Disk ][ devices or other
peripherals. Bug fixes increased the number of hi-res color to 8 and eliminated the
violet and green fringe around characters in text mode.
The emulator for the Apple ][+ includes a disk drive controller in slot two with two Disk
][ drives. This revolutionary controller was probably the first commercial soft-sector
5.25" floppy drive, and was the cheapest ever at the when it shipped at $595.
Minor as these improvements may seem, it greatly increased the desirability of the Apple ][
line and gave a huge boost in sales to the Apple line.
