; This file is used in these builds: ROM System
;
; Change History (most recent first):
;
; <16> 6/14/91 JL Checked in official MPW 3.2ƒ version.
; Fixed casing of dsRectBR and dsRectTL in the dsRectHei and
; dsRectLen equates.
; Removed Line1010, Line1111, FMTErrVect, and AutoInt… equates
; because they are declared in SysEqu.a
; Reverted conditionalized equate of hiIntMask and declaration of
; forROM to match shipped Interface.
; ****************************************************************
; ************* Do not edit this file!!!!!!!!!!!!!!!!!!!!!
; ****************************************************************
; This PUBLIC Interface file should not change anymore. Use
; HardwarePrivateEqu.a instead.
; ****************************************************************
; <15> 6/12/91 LN Removed private interface includes
; <14> 1/30/91 gbm sab, #38: Change the ‘already including this file’ variable to
; all uppercase (for security reasons)
; <13> 1/16/91 JDR (dba) Removed the comment about Topanga.
; <12> 11/26/90 gbm (and bbm) This file is still obsolete. And when we fix all the
; files that include this old version, this one will still go
; away. === the change we made here is: On 7.0 (and other places
; eventually) HiIntMask will be $0700 instead of $0300 all the
; time, not just when on a non-Plus.
; <9> 4/4/90 MSH This file is now obsolete. All equates found here are are now
; found in the beautifully restructured HardwarePrivateEqu.a. Do
; not chage this file. Do not use this file.
; <7> 1/31/90 CV Adding comment for the previous rev. It was deleted when the
; file was checked in.
; <6> 1/31/90 CV Adding bit definition for via1 buffer B for Erickson. On
; Erickson, three lines are used to communicate with EGRET.
; Five lines are unconnected.
; <5> 1/16/90 EH NEEDED FOR ZONE 5. Added bit offset equ for SCC RRO Receive
; Char Available bit.
; <4> 1/11/90 CCH Moving private stuff to HardwarePrivate.a.
; <3> 12/26/89 SWC Replaced "#"s with ";"s for the following comment since the
; AddChange script was messed up when this file got checked in.
; <2> 12/26/89 SWC Added FMCRPUInit as the FMC initialization value to use when
; Zone 5 has a parity chip installed.
;
; <5.1> 11/29/89 SWC Removed all references to OSS ADB since we'll probably never use
; it. Removed NewOSS and all "old" OSS register offsets since all
; we now have are "new" OSS's. Removed FMCRev2 since we're now
; using the final memory controller on Zone 5.
; <5.0> 11/17/89 GMR Fixed RPU base address, to $50F1E000!
; <4.9> 11/14/89 GMR Changed FMCInit value to new setting for parity. Added RPUBase,
; rpuReset equates.
; <4.8> 11/7/89 GMR Added OSSIntRPU and OSSMskRPU equates for the Ram Parity Unit
; additions to the OSS chip interrupt sources.
; <4.7> 8/16/89 BBM added temporary hack to support emacs build.
; <4.6> 7/25/89 SWC Changed FMCInit so that an extra wait state will be done on ROM
; accesses.
; <4.5> 7/14/89 SWC NEEDED FOR AURORA: Made the FMC init value conditional on
; FMCRev2 until hardware freezes. Changed MskSound from 0 to 2
; since sound now works on F-19.
; <4.4> 7/8/89 CCH Put TestInRam macro back in here, since it is used in more than
; one file.
; <4.3> 7/6/89 GGD Added the ROMRelease field to the ROM Header. Changed the
; defaults for NewOSS and FMCRev2 to both be enabled now, Moved
; the FMCRev2 equate to be outside of the if hasFMC conditional so
; that it will always have a value.
; <4.2> 6/30/89 DAF Added equate for vDAC read address register
; <4.1> 6/28/89 rwh NEEDED FOR AURORA: axed MMUSkyHook from RomHeader, in foreign OS
; table now.
; <4.0> 6/28/89 GGD Deleted FrmBufBase which was no longer correct and unused.
; Deleted old SCSI equates. Deleted hwCfgBits and rom85Bits from
; new machines since they now come from the Universal ROM tables.
; Deleted TestInRAM and related equates.
; <3.9> 6/27/89 rwh NEEDED FOR AURORA: changes to get FMC rev 2 working. Also mark
; 3.6 change.
; <3.8> 6/20/89 SWC Removed the following video parameter constants since they're no
; longer used (and there are lomems that contain the correct
; information): maxX, MaxY, screenWidth, screenHeight, scrnRowB,
; scrnBytes, scrnHorRes, scrnVertRes, dVertRRate, SEScrnIcon,
; SEScrnFace, SEScrnI2.
; <3.7> 6/19/89 SWC Added NewOSS conditional so that builds will be easier to do
; while transitioning from the old to the new OSS version.
; <3.6> 5/31/89 rwh added sound chip register definitions.
; <3.5> 5/30/89 GGD Re-positioned the Mac32 equates to be before all other 32 bit
; machines so that it has precedence when multiple machines are
; defined. Changed Mac32 machine number to be 6 to match hafMac.
; Added a few more equates to Mac32 that are needed by the
; universal ROM.
; <3.4> 5/20/89 GGD Added IOP register definitions. Changed IOP base addresses to
; point to the bypass register set, changed register offsets to
; compensate for base address change.
; <3.3> 5/16/89 rwh changed comments for cache enable/disable bit. Improved
; TestInRam. Added MMUSkyHook to RomHeader.
; <3.2> 5/10/89 CCH Changed TestInRam macro to be PC-relative.
; <3.1> 4/30/89 GGD Temporarily defined some equates when on HafMac and universal to
; get build to work Defined more of the VIA bit equates for Mac16.
; <3.0> 4/27/89 CCH Added TestInRam Macro.
; <2.9> 4/13/89 MSH Ramconfiginit changed to work on 3M ram cards.
; <2.8> 4/13/89 GGD Added hwCfgFlags bit definitions for hwCbAUX, which was defined
; but didn't have an equate here, and hwCbPwrMgr to identify the
; presence of a Power Manager on HcMac. Deleted the equate FPUin,
; and change the one place that used it to use hwCbFPU instead.
; Made the names vrtcData, vrtcClk, vRTCEnb consistent across
; machines by adding a leading "v" in some cases. Removed several
; ancient equates that are no longer referenced by the ROM or
; System disk, and would only encourage non-portable code. Made
; TimeSCSIDB to same address on all machines. Removed OldSCSIxxx
; left over from rev7 board support.
; <2.7> 4/3/89 MSH Moved HcMac screen base to the upper half of its address area to
; allow for Quickdraw
; <2.6> 3/14/89 MSH Removed obsolete equates that were used by starttest. Added
; Esprit ASIC register
; <2.5> 3/6/89 GGD Added equates for the remaining (excluding slots) OSS interrupt
; status bits. Added in conditional support for RAM based MacPP
; ROM (default ROM based). Deleted equate ROMDoEject which was an
; absolute ROM address for all machines except onMac (it used in
; PatchPlusROM.a), as part of the shift towards a position
; independent ROM. Moved the SWIM ISM register offset equates from
; SonyEqu.a to here, to be with the IWM register offset equates,
; re-arranged IWM equates. Deleted redundent IWMBase when onHcMac.
; Re-arranged VIA equates, adding vIFR bit definitions to all
; machines, and making VIA register offsets (with the exception of
; vBufD) machine independent. Added record definition for fields
; in base of ROM. Changed RBV register equates to be offsets from
; base of RBV, instead of absolute addresses. Include RBV equates
; when hasMacIIVia2 also, in preparation for universal ROM.
; <2.4> 2/27/89 CSL hanged FrmBufBase, RBV Frame buffer base from slot E to slot 9
; for real machines.
; <2.3> 2/22/89 CSL moved machine definition for HafMac in front of NuMac to avoid
; conflict.
; <2.2> 2/17/89 rwh changed 4Square and F19 to have same Machien type so Macsbug
; works.
; <2.1> 2/16/89 rwh added equate for power off bit in OSS power off control
; register.
; <2.0> 2/16/89 rwh added Fitch Memory Controller (FMC) equates, some OSS equates.
; <1.9> 2/16/89 CSL Move System heap to start at $2000, provide space for 24/32
; memory manager jump vector table

; <1.7> 2/8/89 CCH Moved "Clock16M" outside of HcMac conditional, and moved
; PMgrBase into SysEqu.a.
; <1.6> 2/8/89 MSH Added equs for Topanga support.
; <1.5> 1/17/89 GGD Added sccIntMask to allow MacPP to build.

; <1.3> 11/17/88 DAF Added equate for vDACPixRdMask
; <1.2> 11/17/88 GGD Increased size of Toolbox Dispatch table onHcMac to be the same
; size as on the MacII, changed HeapStart to correspond.
; <1.1> 11/11/88 DAF Added hasRBV equates for vDAC; moved FrmBufBase up
; <1.0> 11/9/88 CCH Adding to EASE.
;
; <1.9> 11/6/88 GGD Port to IoMac hardware.
; <1.8> 11/2/88 djw Added FrmBufBase for RBV and RomBSize for 512K roms.

; <C920> 10/27/87 rwh Changes for Modern Victorian port (onMvMac). Attempted to make conditionals
; easier to understand with "IF machine1... ELSEIF machine2...ENDIF"s.
; Formatted for readability. Deleted slot address & video register equates,
; since nobody uses them AND they are wrong!
; <C918> 10/26/87 MSH Must continually make more things truly conditional here.
