This software package is an Apple ][ / Apple ][ Plus emulator for UNIX
systems.  It emulates a 6502 microprocessor, contains Apple ][ ROM code,
and emulates a few Apple ][ memory mapped I/O features.

Usage syntax:

	Apple.II [-t] [-m] [-i]

If no parameters are specified, then an Apple ][ Plus (autostart and apple-
soft) are selected.  Trace (-t) mode causes the state of the processor to be
printed to the standard error output at the end of each 6502 instruction.
The Original Monitor (-m) and Integer Basic (-i) options override the default
ROM configuration.

To exit the simulation, type Control - A.

Currently, the only I/O features supported are Page 1 40-Column text,
keyboard input, keyboard strobe, and speaker toggle (sends beep to terminal).
Unimplemented 6502 instructions are executed as NOPs.
