derived/shimmed from AppleWin source).

* Fixes for Linux Joystick (both PC Joystick and Emulated Keypad/Arrows)
* Simplifications to interface modes and preferences
* Interfaces are now 80columns
* Removed support for console SVGAlib

Fri Dec 18, 1998 : Michael Deutschmann <michael@talamasca.wkpowerlink.com>
* Started revision 0.7.1
* configure.in: set version
* Makefile.am: distribute '.apple2'
* src/Makefile.am: Changed filename of SVGA apple2 back to just
`apple2' (from `sapple').
* src/Makefile.am: Fixed bug - seperate apple2-80.o was not being
made.
* src/apple2.h: comments added regarding flag bits.
<Lotsa changes occured between 0.06 and 0.7, but they were
not recorded.>
Changes in 0.06 (Aug 98) : Aaron Culliney <aculline@bbn.com>
* Separated SVGAlib specific stuff into svideo.c. Added X
Windows frontend support in xvideo.c. The X frontend works
by doing an X(Shm)PutImage() of the emulator's framebuffer
around 30 times a second. This saves us from changing the
internal video routines (they assume direct access to an
8bit framebuffer), and it's a heck of a lot faster than
trying to do an XPutPixels() on each change. The X frontend
only currently works for 8bit displays. Make sure you run
it using a mode (specified in XF86Config) that has a bit
depth of 8 (not 16 or greater).
* We now build three versions of the emulator: svideo_320x200,
xvideo_320x200, xvideo_640x400. The last one really isn't
640x400 for optimization reasons (568x384) although it
probably should be... Sorry, but there's no support for
switching resolutions on the fly, we ifdef it in with a new
define "_640x400".
* Provided 80column support for the 640x400 X version. Now
you can PR#3 (running as //e) and get 80 columns. This
change required a resolution of at least 560 horizontal
pixels (Apple //e specs).
* Both SVGA and X versions need to be suid root (for PC
speaker port access and SVGA stuff). But both versions now
give up root access during video initialization. This means
that disk access is now done as *you* (not root) even when
g(un)zipping images for loading. Before images would be
g(un)zipped as root. There was something about this that
made me uneasy... Now it's up to you to give the
appropriate user/group permissions to your disk image
repository. I make no claim about the security fitness of
this emulator. See the other READMEs and files for more
information/disclaimers.
* Did a 180 on the disk image selection menu. <RET> now tries
to open disk images as read-only, 'W' for both read-write.
Of course this will only work if you have the correct file
permissions set (see above). I find this more convenient
b/c I play alot of the arcade games where you don't ever
save game state.
* Removed the disk "Information" submenu. I never use it. Do
you?
Changes in 0.05 (Feb 98) : Aaron Culliney <aculline@bbn.com>
* Added support for 65c02 instructions. The programs that
I've tested which use them work just fine.
* Added support for 128k //e EXCEPT 80 column mode, B/W
DHIRES mode, and MouseText character set. The two
unimplemented video modes require major changes to current
video routines, thus a next version... New supported images
are copy ii+ 9.0, diagnostics //e, marble madness, airheart,
legend of blacksilver, pirates!...
* Fixed some old problems with HIRES colors being off around
byte edges in interpolated/color modes. but we still give
you the option to use these "lazy" modes since emulation is
faster with them enabled...
* You now have several new options in your .apple2 file. I
suggest either copying the distributed one over your
existing one, or merging the changes in.
* Fixed some potential security bugs where a user could
traverse into sensitive directories by using the disk
selection interface. The current emulator version is not
guaranteed to be foolproof since it has to be installed suid
root for normal users to use it. Sysadmins should take
extra precautions as they see fit.
* Added and deprecated some options in the debugger interface
to support the new 128k //e. see the DEBUGGER file for more
info. DEBUGGER support is not default compiled in.
* Added some extra options to the .config file that you build
into the emulator. One big one: a way to set the max delay
count in the emulator to bring Apple ][ emulation rates down
to normal on high end pentiums!... 100 is the default delay
rate (which works just fine for low end 386-Pentium100's).
Changes in 0.04 (June 97) : Aaron Culliney <aculline@bbn.com>
* Added PC Joystick Support. You must have the joystick
kernel loadable module 0.8.0 correctly configured and
installed to use this feature.
* Changed the way the emulator handles the language card
memory space. We no longer patch rom/ram on lc_c08x
functions. I did this because under certain conditions the
previous versions of the emulator would run a lot slower.
Now you may notice the emulator running a tad slower in
general (because of the range checking), but Ultima 4 and
Arctic Fox (formerly unplayable) should now be just fine.
* Changed the way the .apple2 preferences file is handled. I
Did this mainly to support saving of PC Joystick parameters,
and I'd rather let flex do the dirty work of regexp
matching.
* Changed the disk interface and main interface menu. In the
disk interface, you can now see which disk is in the drive,
and with what permission <rw1> for read/write drive 1. You
can eject this disk or force it to be write-protected. In
the main menu screen, you have more parameters to play
around with (associated with the pc joystick add-on).
* Disk image files are now opened with user privileges, not
root privileges, even though the program is suid root.
gzip'ed disks are still handled as root, but we no longer
call the unsecure system() to do the dirty work. Instead we
fork and directly exec "/bin/gzip".
* General bug fixes and enhancements.
Changes in 0.03: (Jan-Feb 97) : Aaron Culliney <aculline@bbn.com>
* Fixed language card initialization bug.
* Improved colors. Seems that Greens and purples we're
switched around. The colors are still slightly off, and
color interpolation seems screwy (TODO).
* Added apple II debugger interface. This requires flex
version 2.5.2. (You can compile this into the program or
leave it out.) Type F7 to get into the debugger and type a
'?' to see a command summary. Check out the file DEBUGGER
for more info.
* Added support for standard 232960 .nib disks.
* Added a more intuitive interface to selecting disks. You
can now traverse forward and backward in a directory
hierarchy with the base directory set by your .apple2 config
file.
* changed keymap: shift-p = @ and shift-N = ^, just like my
old II+ keyboard.
Changes in 0.02: (8 Dec 1995)
-----------------------------
* Ctrl-C will not kill the emulator with newer SVGAlib. Please
use SVGAlib > 1.2.9 for best results.
* Rudimentory REPT key handling. It's too fast though.
* The assembler files now compiles under ELF.
* Not every SVGA card can do page-flipping. The emulator now
checks for this and fall back to VGA if it can't.
* Keymap has changed a bit. Backspace and ']' is now <-, '[' is
REPT.
* Disk extension changed to the more common .dsk (and a2d.info to
dsk.info).
Changes in 0.01: (9 Oct 1994)
-----------------------------
* Standard VGA support with some performance degradation.
(When page flipping occurs, 64K memory banks are swapped;
hence the performance degradation.)
* -vga flag switch added, e.g. "apple2 -vga"; forces standard
VGA detection.
* (Trident) TVGA8900 page flipping bug fixed.
* File names may now contain any character codes. (The previous
version had some problems with compressing/uncompressing file
names with extraordinary characters.)
* Diskette selection retains last cursor position.
