<p>
For anyone browsing Catakig's source code, hoping to make some sense of it, here's a brief summary . . .
<h3>FILE (DIS-)ORGANIZATION</h3>
<p>
The source code is grouped into three major parts:
<ol>
<li>the MacOS X Cocoa application (in Source/Cocoa)
<li>the Apple II emulation library (in Source/LibAppleII)
<li>generally useful C and Objective-C stuff, not specific to this project (in Source/Misc)
</ol>
<p>
Part 1 depends on parts 2 & 3. Part 2 depends on part 3. Part 1 is allowed to have Cocoa-specific code, whereas the other two are meant to be portable, and should rely only on <i>FoundationKit</i>, <i>AppKit</i>, and standard Unix APIs.
<p>
File <b>Prefix.pch</b> is the project's pre-compiled header file. Its content is
implicitly included by every source file.
<p>
The <b>LibAppleII</b> emulation library is driven from the outside. (You call it -- it doesn't call you.) The client of the library, the surrounding application, is expected to pass along all relevant user input, to call the 65c02 interpreter, and to call the video frame renderer, whenever these tasks are needed. The library doesn't initiate any action on its own.
<p>
Documentation of the source code is pretty scant right now. Most methods do have a brief summary at their beginning, and most files have a few comments at the top describing the contents. But there isn't anything right now to document how the whole thing hangs together.
<h3>DESIGN GOALS</h3>
<p>
Adhere as much as possible to POSIX, OpenGL, and the common subset of Cocoa and GNUStep. Maybe port someday to generic Linux/BSD + GNUStep platforms. OpenAL might be a another good standard, for audio output.
<p>
Target MacOS X 10.3, and avoid 10.4+ features. (Occasionally review this decision though.) It would be nice to support 10.2 as well, as I was trying to do initially, but it seems time to move on. Note that MacOS X on Intel must always at least version 10.4.
<p>
For now, don't bother supporting arbitrary Apple II peripherals in arbitrary slot configurations. Rather, aim for a "canonical" Apple II with the same feature set across all models. These features are:
<ul>
<li>a printer, slot #1
<li>a Mockingboard sound card, slot #2. (The IIc has a serial port for modems in
slot #2, but this can be used to talk to the Mockingboard D. Supporting modems under emulation is probably pointless today anyway.)
<li>a ThunderClock-compatible clock card, slot #3?
<li>a "Slinky" RAM card, slot #4
<li>a pair of ProDOS/SmartPort drives, slot #5
<li>a pair of Disk II 5.25-inch drives, slot #6
<li> mouse?, slot #7
</ul>
<h3>NAMING CONVENTIONS IN THE SOURCE</h3>
<p>
In general, identifiers are in mixed-case form (e.g. "doItNow") -- except C pre-processor macros, which follow the ancient C tradition of being all uppercase, with words separated by underscores ("DO_IT_NOW").
<p>
All LibAppleII identifiers in the publicly visible scope, except enum constants, begin with "A2".
<p>
Enumeration constants begin with "kf" when they're flags (integers having a single 1 bit, e.g. 0x400), "ks" when bit-shift values (0 to 31), "km" when bit-masks (e.g. 0x3FF), and just "k" otherwise. Public enumeration constants also have "A2" in their prefix. Flag and shift enum values are often defined in pairs: e.g. "kfALTZP" and "ksALTZP".
<p>
Names of object instance variables begin with "m" and are mixed-case ("mFavoriteColor"). This convention seems to go against popular Objective-C practice, but I don't care. It helps me.
<p>
Methods supplied by the author that don't exist in the standard class
libraries have capitalized names. For example: "InputChar" and not
"inputChar" -- but on the other hand "keyDown" and not "KeyDown". In other
words, lower-cased methods will have some pre-defined purpose in the system
libraries, because of class inheritance, whereas the upper-cased methods are entirely
new additions. Again, this is a personal convention that helps me.
<p>
Methods begining with an underscore ( _ ) are considered private to the class,
for internal use only. Objective-C has no "private" attribute like C++ does
to enforce this behavior however. Any Objective-C message can be sent to
any object at any time. But the underscore alerts the reader that the method
isn't supposed to be called from just anywhere.
<h3>CODING HABITS OF THE AUTHOR THAT WILL ANNOY YOU</h3>
<p>
Hard tabs are used in the source, and are expected to be 4 spaces wide.
Might switch to soft tabs (all spaces) at some point.
<p>
The author often exploits the fact that C literal strings are arrays
of constant characters, that C characters can also serve as small
integers, and that therefore short literal strings make handy little
in-line lookup tables of small integers. For example:
<pre>
number_of_one_bits = "\0\1\1\2\1\2\2\3"[n]
</pre>
You're probably entitled to be outraged at this practice.
<p>
Comments ending with "??" or "!!" are considered temporary, and not part
of the settled in-line documentation -- if such a thing will ever exist.
These annotations usually mark code that is volatile, experimental, or
whose need is questionable.
<p>
There are some C99 (and non-C89) features used pretty frequently: (1) declaring
for-loop variables in-line; (2) initializing structure fields by name
instead of by position. The first one is pretty well known, but use of the second feature doesn't seem very widespread and might be a surprise to some.
<p>
The author prefers using "and", "or", and "not" over "&&", "||" and "!".
Macros defining these pseudo-keywords are in the header <b>Prefix.pch</b>.

==== Preferences ====
* Let user pick the colors of color video. Or, NTSC vs. PAL.
* Checkbox for cassette tape audio output.
* Skip lines in monochrome/color video (two separate checkboxes).
* Checkbox for Mockingboard (when implemented).
* Checkbox for disk drive sound effects (when implemented).
* "Start Apple IIs with power already on" checkbox.
* Sound volume control in application?
* Add "success" and "failure" feedback beeps, with ability to disable.
* Mouse-joystick mapping assumes only one screen, the main one.
Should instead range over the entire desktop.
==== the Apple II window ====
* Make dashboard into a drawer? A toolbar? Anyway, let user hide it.
* Optionally show annunciator lights in dashboard. Not on IIc though.
* Need per-window preferences?
* Are we capturing screens in the best way?
* Drag & Drop disk slots
==== Miscellany ====
* Internationalize displayed text.
* Add built-in help pages: HTML or PDF
* Add sound recording.
* Add QuickTime movie recording.
* Support real joysticks, via IOKit.
* Add more control over paddle buttons.
* Use third-party Cocoa kits? OmniGroup's?
* Rethink error handling and reporting! Add Log window?
* Add built-in PDF/HTML help.
* Would Xcode build phases be useful?
* Use zlib 1.2.3? nulib?
* Add OSX icons for '.rom', '.hdv' files. Others?
* Rename the 'MyDocument' class to something more inspired. (This is a
relic of the original project stationery.)
* Save and restore states. (Open, Save, Revert, etc.)
* Quick save and restore?

==== Non-functioning Apple II Software (that should work) ====
* Rescue Raiders? Usually launches, but sometimes re-boots mysteriously.
(Could just be the disk image I'm using.)
* Stellar 7? Seems okay now, but wasn't working earlier.
* Apple Panic, GraForth. Something wrong with our keypress buffering?
==== CPU ====
* Find quicker Z-flag query expression? (Rethink ZF flag.)
* Use rotated opcodes: op<<6 | op>>2 ?
* Keep A in a local variable?
* Implement old 6502 ADC & SBC behavior (different flags than 65c02)
* Video floater bytes not correct yet.
* On ][ and ][+, RESET should not affect the language card state.
* Keep 'scanLine' in upper bits of 't', instead of extra variable.
* Peripheral expansion ROMs not being swapped in correctly.
==== Video ====
* Review D/HGR rendering. Glitches still apparent?
* Support European screen glyphs.
* Support European (PAL) color palette.
* Implement the "bizarre" (and useless) GR video mode?
* Simulate color burst for text in graphics mode.
* Implement Videx 80-column card for IIo and IIp models?
* Eliminate need to scale array index by 4 when using 'vpix' tables?
==== Audio ====
* Add Mockingboard emulation.
* Add sound effects to printer and disk drive activity.
* Support cassette tape input? Probably not worth it.
* There are occasional pops in the audio output.
==== Disk Drives & Image Files ====
* Support BZ- and GZ-compressed disk image files.
* Use track size of 6384-6400 bytes instead of 6656?
* Infer DO/PO format of 140K disks by examining their contents.
* On computer Reset, does the IWM mode register revert to 0?
* Update checksum on modified DiskCopy 4 images.
* Does IWM mode register change after RESET?
* Support FDI disk images? NB2?
* Forbid Disk II drives accepting 2IMG-PO disks > 140 KB.
* On real Apple II with IWM, verify IWM status register value under all
possible drive contents: none, read-only, read-write.
* Failure to load a drive should _not_ empty it?
* Need to regularize NIB tracks when loading?
==== Printer ====
* Not processing rubout characters ($7F) yet.
* The Flex scanner is not re-entrant, and not thread-safe. Use 're2c'?
* Output PS should be friendly to A4 paper sizes, and PDF distilling.
* Use PDF-lib library for printing to PDF?
* Preferences:
LF after CR, yes or no
7 or 8 bit data path
card DIP switch states
page size US Letter or A4
line width 40 or 80
* Epson emulation:
Ibsen font bounding boxes needed
Tab stops are not always a constant width.
Graphics character set; European character sets.
Handle rubout and backspace characters properly.
Vertical tabs not handled.
==== Model-specific Features ====
* The IIc+ doesn't work yet. Worth bothering with?
* IIc: provide a 40/80 column switch?
* IIc: detect various ROM versions, an act appropriately. In particular,
the mouse firmware can be in slot 4 or 7, the number of ROM banks can
be either 1 or 2, and expansion RAM might or might not be available.
* IIc: reading $C048 should reset the X0/Y0 interrupt flags.
==== Miscellany ====
* State saving and restoring!
* The Apple ][ and ][+ are wasting 64KB for aux. RAM that's never used.
* Add Z80 and CP/M support?
* Emulate RAMWorks card? ThunderClock?
* Use ObjC exceptions instead of error codes? (Requires MacOS 10.3+)
How about using NSError?
* Use NSFileHandles or NSStreams instead of Unix FDs and FILE pointers?
* Add Apple II mouse support.
* Implement the Parallel Interface Card? It's much simpler than the SSC.
* Eliminate non-POSIX calls?
* Have different models inherit from a base class?
* Save and restore NSUserDefaults for the library.

========== BUILDING CATAKIG IN XCODE 2, FOR MACOS X ==========
The information here should be helpful on those occasions when the XCode
project needs to be re-constructed -- either because Apple comes out with
a new, radically different version of their IDE (as they've done twice
on my watch), or because the project file gets lost or damaged. This
information should also be helpful for writing a Unix "Makefile" or
"autoconf" script, should anyone want to do that at some point.
-- CK
==== Files in the project ====
For source code, everything in folder "Source". Just drag and drop the
whole folder into the project.
For Resources, everything in folder "More-Resources". Again, just drag and
drop into the project's "Resources" group.
The '.xcconfig' files are used to set target configuration options, instead of XCode's dialog interface to them. File 'debug.xcconfig' is for the Debug target, file 'release.xcconfig' is for the Release target, and both incorporate 'common.xcconfig'.
==== Linked frameworks ====
* Cocoa, OpenGL, AudioUnit, CoreAudio
* Carbon (needed only for the 'SetSystemUIMode' function)
==== NIB notes ====
* The single AppController object is the delegate for both the main
NSApplication and NSMenu objects.
* The main application object is actually an instance of 'MyApplication',
which subclasses NSApplication. Subclassing is done so that we
can override '-sendEvent'.
* An Apple II window's ScreenView is also its initial (and permanent)
First Responder. The Apple II object is the next responder after
that, then the NSWindow and the usual responder chain.
* Each Apple II NSDocument is the delegate of its window.
* Menu command "New" was renamed "New Apple II" -- and, instead of
sending -newDocument to First Responder, sends this message to the
AppController object. (This is so we can put up the "New Apple II"
panel first.)
