|
|
; Change History (most recent first):
|
|
;
|
|
; <2> 3/10/92 PN Change sysbeep to upper case for the linker
|
|
; <16> 6/12/91 LN added #include 'SysPrivateEqu.a'
|
|
; <15> 6/12/91 LN Removed #includes for private interfaces from public interfaces.
|
|
; Changed #include 'HardwareEqu.a' to 'HardwarePrivateEqu.a'
|
|
; <14> 8/21/90 KIP Fix a with statement.
|
|
; <13> 8/21/90 KIP Try to play the ROM beep if the resource ID in PRAM is not
|
|
; found; switch logic of sysBeepState value.
|
|
; <12> 8/13/90 KIP Make SysBeep look again for sound volume of zero and flash the
|
|
; menu bar (Neil changed _SndPlay to do this, but that was the
|
|
; wrong thing to do).
|
|
; <11> 6/12/90 DDG NEEDED FOR SIXPACK: Fixed previous comment.
|
|
; <10> 6/11/90 CV NEEDED FOR SIXPACK: Removing test for sound active and sound
|
|
; volume equal to 0 because they are in the sound manager now.
|
|
; <9> 6/2/90 NC NEEDED FOR SIXPACK: New Sound Manager can disable SysBeep for
|
|
; presentation purposes. SysBeepPatch now looks at the global and
|
|
; exits if sysbeep is disabled.
|
|
; <8> 5/29/90 DDG NEEDED FOR SIXPACK: Changed all the sixpack conditionals from
|
|
; six-point-oh-seven to six-point-oh-six.
|
|
; <7> 3/20/90 DDG Changed $610 to $606 in all the system version conditionals.
|
|
; <6> 2/5/90 DDG Fix SysBeep by including it in the sound manager patch instead
|
|
; of the individual patches for each ROM. (Neil [NC] actually did
|
|
; the fix)
|
|
; <5> 2/3/90 NC SysBeep is now patched by the Sound Manager. This file should
|
|
; now reside in the SoundMgr folder but BBS won't let me put it
|
|
; there!
|
|
; <4> 2/1/90 NC How about using asm Ifs instead of C #ifs?
|
|
; <3> 2/1/90 NC Conditionally remove the SoundActive check because new Sound
|
|
; Manager really returns errors.
|
|
; <2> 1/4/90 dba get rid of warning caused by unnecessary branch; also get rid of
|
|
; MacPlusBeep/MacSEBeep symbols; this file will become part of a
|
|
; Mac Plus/Mac SE patch file and will use Bind in the future
|
|
; <1.0> 11/16/88 CCH Added to EASE.
|
|
; 7/8/88 bbm <S529> Made massive changes to SysBeepPatch.a. Cleaned up some
|
|
; code. We now jump to rom if extra parameter ram is not present,
|
|
; or if we are playing 'snd ' 1 on a MacPlus or MacSE. Since the
|
|
; new sound manager uses timer one, any application that called
|
|
; SysBeep and used timer one would die on System 6.0. If a user
|
|
; chooses simple beep, the sound manager wonÕt be called on a
|
|
; MacPlus or MacSE, so the application wonÕt croak.
