|
||
; Change History (most recent first):
|
||
;
|
||
; <3> 2/17/92 kc Change case of SETUPNOTIFICATIONMGR, USENEWNMTASK,
|
||
; KILLOLDNMGLOBAL GLUNMINST, and GLUNMRMV.
|
||
; <2> 2/13/92 RLM Patch roll-in
|
||
; <3> 12/4/91 csd #1016448: Added support for Scruffy. Changed the patch to
|
||
; InitApplZone which calls FlushApplNM when Scruffy is running
|
||
; because Scruffy’s version of InitApplZone already calls
|
||
; FlushApplNM.
|
||
; <2> 9/21/90 VL Added patches to patch out routines in ci and portable ROMs for
|
||
; Notification Manager.
|
||
; <1> 6/26/90 DTY First checked in. This file was Originally
|
||
; NotificationMgrPatchTail. Since the Notification Manager is now
|
||
; a linked patch, NotificationMgrPatchHead is no longer necessary.
|
||
; This file now uses the new LinkedPatchMacros, instead of the old
|
||
; PatchMacros.
|
||
;

CASE OBJ
|
||
|
||
|
||
; The Notification Manager needs to be implemented on the Plus, SE, and II ROMs.
|
||
; And it needs to be patched on IIci and Portable ROMs. The only routine that is
|
||
; currently patched is NMTask but we also have to initialize the globals (after getting
|
||
; rid of the old ones).
|
||
|
||
; Initialize the Notification Manager
