This stuff's probably been here before a lot, but it was said to me (sorta) that it may be useful.  Some are 
for ProDOS, some are for DOS 3.3, and some are for Applesoft BASIC in general.  A lot of the DOS 3.3 stuff 
came from Bert Kersey's DOSTalk Scrapbook.  As usual, I claim no responsibility for any damage, etc. these may 
do.  Some of the info may be less than 100% accurate; I haven't updated this in a long while.  Without further 
ado, here's my really big PEEKs, POKEs, and CALLs and stuff list.

A little more ado:As always, feel free to email/post to me questions about this stuff.  I don't worry about 
too much email, as I won't have internet service after 2 weeks (approx.)

If 43+ errors are going to be handled by ONERR GOSUB or ONERR GOTO, use this
subroutine in your program:

The proper syntax for reading a 2-byte number:
     Q=PEEK(B)+PEEK(B+1)*256
   Q now equals the new value and B should have been previously set to the
   starting address of the 2-byte number
The proper syntax for storing a 2-byte number:
     POKE B+1,Q/256:POKE B,Q-(PEEK(B+1)*256)
   Q should have been previously set to the value to be POKEd in and B should
   have been previously set to the starting address of where the value is to
   be stored
FOR A=46010 TO 45999 STEP -1:PRINT CHR$(PEEK(A));:NEXT
     Shows you the current DOS 3.3 disk catalog header
To stop a DOS 3.3 catalog after it waits for your keypress, enter (in hex):
     BCDF:20 0C FD C9 83 D0 03 4C 7F B3 60
PRINT PEEK(54)+256*PEEK(55) Returns the address of the current output routine
PRINT PEEK(56)+256*PEEK(57) Returns the address of the current output routine
     if DOS is active, then you use:
PRINT PEEK(43603)+256*PEEK(43604) Returns the address of the current output
               routine
PRINT PEEK(43605)+256*PEEK(43606) Returns the address of the current output
               routine
To determine what to POKE into 40192 to move the DOS buffers to put your
     machine language routine there, use the following formula:
     DB=40192-(L+38)
     You would then POKE 40192,DB and CALL 42964 to make DOS rebuild the DOS
     buffers, and then load your machine language routine into DB+38.

                  DOS Buffer #| Data Buffer  | Filename Field

There is not enough detail provided with mnany of these to actually make
use of them, unless you know what context they are defined in.

Only while waiting for input with KEYIN.

The above are mostly for Applesoft BASIC.  Integer BASIC has a completely
different zero page layout, and the Applesoft zero page variables are not
relevant if you are writing a standalone SYS file.

In addition, $1F is allegedly used by the monitor (if you believe Apple's
memory usage charts).

>$100-$95FF = Free

$100-$1FF is the stack.  It certainly isn't "free".

$200-$2FF is the input buffer, so must be used with extreme caution (under
ProDOS with a Thunderclock installed, parts of it get overwritten on every
ProDOS call).

$300-$3CF is free.

$3D0-$3EC is usually used by DOS 3.3 or BASIC.SYSTEM for entry point vectors.

$3ED-$3FF is used by the monitor for various hooks.

$400-$7FF is the text screen, including screen holes which must be preserved.

$800-$95FF is usually free under DOS 3.3 or BASIC.SYSTEM, but the upper
end may vary depending on MAXFILES (DOS 3.3) or the number of open files
(ProDOS).  In addition, BASIC programs use part of this area, so you
cannot assume it is all available for a machine language subroutine being
called by a BASIC program.

A SYS program under ProDOS can also use $9600-$BEFF.

>$9600-$BFFF = DOS 3.3

Unless you've changed the number of buffers with MAXFILES.

>$9600-$BEFF = BASIC.SYSTEM

Unless there are any files open.

The following table of entry points ($9D5E through $AAB1) are only
relevant for DOS 3.3.  (I haven't checked the addresses.)

>$9D5E = Routine called after RESTART is pressed
>$A963 = Two-byte value that is the max. value allowed w/the L parameter
>$AA57 = Current MAXFILES setting
>$AAB1 = Default MAXFILES setting

The following table of entry points ($BE43 through $BE6B) are only
relevant under BASIC.SYSTEM.  (I haven't checked the addresses.)

>$BE44 Input file active (status)

>$BF00-$BFFF = ProDOS's global page

Got that one right.

>$C000-$FFFF = ROM

$C000-$CFFF is not ROM.  It is the I/O space, which may include ROM
provided by I/O cards.  In the IIe, IIc and IIgs, the $C100-$CFFF can be
switched to access ROM areas.

$D000-$FFFF may also be switched to the language card (bank switched RAM),
with two alternate 4K banks appearing at $D000-$DFFF.

>$D000-$F7FF = Applesoft BASIC
>$E000-$F7FF = Integer BASIC

Actually, Integer BASIC finishes considerably earlier than $F7FF.  The
remainder of the ROM is used by Sweet-16 and the Mini-Assembler.

>$F800-$FFFF = Hex. Language

Pardon?  Try "Monitor firmware".

(And this is only true in the ][/][+.  In the IIe and later machines,
parts of the monitor firmware are burrowed away in other ROM areas.)

>976 = Warmstart entry

Also known as $3D0, only relevant under DOS 3.3 or BASIC.SYSTEM.

>43140-43379 = DOS 3.3 commands
>43380-43581 = DOS 3.3 error messages
>45991-45994 = DOS 3.3 file-type codes

>46010-45999 = Disk volume header (backwards)

The above line is for DOS 3.3 only.

This is only valid in 40-column mode.

This doesn't even make sense.  PEEK(40) and PEEK(41) access the low order
and high order byte of BASL, which is the pointer set up by BASCALC to
point to the current screen line.  To calculate the address of the current
line, you should use PEEK(40) + PEEK(41) * 256.  PEEK(36) then gives you a
horizontal offset into the line (only in 40-column mode).  A '32' is an
inverse space.

If you tried to use PEEK(40) + PEEK(41) * 156, you would be pointing
somewhere earlier in memory, and might overwrite something important with
a space character.


.... and so it continues.  It would probably take me an hour to check and
clarify the rest of these properly.

My sincerest apologies for the crap/good stuff ratio of the Big PEEKs, 
POKEs, and CALLS list I posted a while ago.  It has been brought to my 
attention that certain parts are just plain WRONG. (Such as the bit 
about making the cursor be invisible or not flash.)

If you want help with any of the info on The Chart, you can either post 
it or mail me before 8/16/96, and I'll see what I can do to help.  Some 
of the stuff on The Chart refers to machine languge programming (Yes, I 
know that bit about $60 returning you to BASIC is inaccurate), and I 
can't teach everybody how to program in machine language with the time 
left before my account dies.  Maybe later :)

I know that many parts are vague (i.e., whether something's a ProDOS 
PEEK, or a DOS 3.3 PEEK). (This is because its original purpose was 
mostly to jog my memory of what the actual numbers were, and I'd mostly 
memorized which are for ProDOS and which are for DOS 3.3, since *I* 
typed this thing up.)  Many of the DOS 3.3 things in especial, have not 
been tested by me.  I have also forgotten totally how to use that 
routine that supposedly helps you if your Applesoft BASIC program 
encounters "43+ errors" (I got that from an old white & green 
spiral-bound book called something like _Applesoft ][ Programming 
Manual_)

I would do an update, but my internet account dies in about 1 week, so I 
probably won't have time.  Right now, I am working on arranging and 
commenting a pair of disk images of my earlier works.  The section in 
The Chart about pokes for the music routine should become more clear 
once you have these images.  I'll also try to make a couple of .SHKs, 
and upload them somewhere (suggestions as to where would be VERY 
welcome).  Suggestions to NOT upload these images at all is only 
semi-welcome ;)

Since I only have 1 week to comment all of my uncommented code (I think 
there's around 90 programs (they're small; I didn't have much attention 
span back then)), it will probably still be something less than totally 
self-explanitory.  As most of the programs will be small, the images' 
main purpose is educational (learn by example), but there will be a few 
programs that I would consider actually (somewhat) useful.

It may be about a year before I get net access again.  When I do, the 
first places to look for me would be the Apple // newsgroups. :)  I 
subscribe to almost all of them, and you will be able to get my new 
email address there.  Until then, you'll have to settle for talking 
about me behind my back.  (Go ahead, I guess I inadvertantly created 
more questions/problems than I answered with The [stupid] Chart!)

I guess that about covers it for now...
