; Change History (most recent first):
;
; <SM4> 10/28/92 SWC Changed SlotEqu.a->Slots.a.
; <SM3> 6/30/92 kc Roll in Horror, comments follow:
; <H4> 6/10/92 djw Add new selector for doSecondaryInit (a private routine)
; <H3> 6/10/92 djw Add new private trap macro's for AddCard, RemoveCard,
; and CheckSlot.
; <SM2> 5/17/92 kc Add get sGetSRTEntry vector number.
; <5> 1/7/92 RB Added a couple of records structures used to identify faulty
; drivers in Apple display cards.
; <4> 1/30/91 gbm sab, #38: Change the already including this file variable to
; all uppercase (for security reasons)
; <2> 1/17/90 djw Add new slotmgr private selector GetBoard
; <1.9> 6/30/89 djw removed pSlotStatus.
; <1.8> 4/16/89 GGD Added new data structures used by SlotInterrupts.a and
; VerticalRetraceMgr.a
; <1.7> 4/12/89 djw Removed including slotequ.a and duplicate state constants
; (state_sdminit,...)
; <1.6> 3/28/89 djw added an SRT entries count to globals. Added macros for private
; routines, added last SRT ptr in globals.
; <1.5> 3/12/89 djw changed srt link block and added some mark values, deleted
; SRTlastBlk ptr in globals and substituted expansion chassis
; support fields.
; <1.4> 3/1/89 djw change srrblock flag field from byte to long
; <1.3> 2/20/89 djw added SRT header record definition, added slot mgr globals
; record. added flag field to srrBlock for enable/disable.
; <1.2> 1/6/89 djw Add slotVNum for slot version number
; <1.1> 11/17/88 CCH Added stuff from system build.
; <1.0> 11/9/88 CCH Adding to EASE.
; <1.0> 10/24/88 djw Adding for the first time into EASE.
; 1/10/88 djw created - removed sSDMRecord and state equates
