Apple ][

Known issues:
Optional cassette drive not yet supported; in fact, no peripherals are supported
(bug #477)
Colors are incorrect (bug #475).
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.

Usage:
Upon booting, you'll get the ROM monitor prompt ('*'), from which you can
examine/modify/run at different memory locations. (Note: you would normally need to press
RESET to get to the prompt, but this doesn't seem to be necessary in MESS.)
From the Monitor, press control-B then ENTER to get to Integer BASIC, which uses the
greater than prompt ('>').
You can invoke the mini-assembler by entering 'F666G' at the Monitor.
To backspace, use the left arrow key. The "Backspace" key is mapped to the Apple ][
"DEL".

History and Trivia:
The Apple ][ is an improved version of the Apple 1 kit computer first released in 1977.
Along with the TRS-80 and the PET, it constituted one of the "second-generation" of
computers, aimed at the general user rather than the specialized hobbyist.
The Apple ][ featured a beige plastic case, color graphics, and seven (eight?) expansion
slots. It included a version of BASIC called "Integer BASIC" on the ROM which came with
the machine.
It was an excellent home gaming platform. It shipped with two game paddles (various
models were used) and supports up to four. It also included a built-in speaker.
The cassette interface required a cassette recording deck and was quite finicky. The
treble and bass on the cassette deck had to be fiddled with in just the right way.
