Undocumented Gestalt Selector Codes
'Undocumented' means to me: not mentioned in Inside Macintosh VI.
Format used:
****'selector code' (Application added selector)
name (description, documentation) OR description
CONST declaration; (remark) *ref.number to source
Some constant-names may not originate from official publications.
Any bitpattern described is what I or others found
on their machine with their configuration.
I don't have all the documentation or knowledge and I don't want to.
I would like to see this list as a combined effort by different
people who have together access to a wide area of information.
If you wish to give me more information or correct the information
in this list, please mail me at <depricated>
If you read this list in Usenet group comp.sys.mac.programmer: you
can also read it by using finger to the same address.

****'admn' (AppleShare Admin appl)
gestaltAppleShareAdminAttr (not documented at all)
gestaltAppleShareAdmin = 'admn';
gestaltAppleShareAdminPresent = 0; (present = running, selector
exists when appl has ran,
if still running bit is set)
****'atkv' (System)
gestaltATalkVersion (see also TN311)
Returns AppleTalk version in 4-bit words
gestaltATalkVersion = 'atkv'; *3
****'AzNe' (NameView cdev)
unknown
****'BSDa' (CloseView cdev)
unknown
****'bugz' (System [Tuna Helper]/Tune-up ext)
probably used to communicate between the Tuna Helper
and the Tune-up extension about repaired errors.
The value returned by 1.1.1 is one bit set more
then 1.0.

additional responses exist but unknown (bit 1,2,3)

gestaltComponentMgrAttr (Component Manager)
gestaltComponentMgr = 'cpnt';
gestaltComponentMgrPresent = 0; ???
****'dict' (System)
gestaltDictionaryMgr (System 7.1 Dictionary Manager,
not documented at all)
gestaltDictionaryMgr = 'dict';
new System 7.1 responses exist but unknown
****'eajt' (System)
gestaltEasyAccessJTable (not documented at all)

Returns the base address of the Easy Access jump-trap table
****'ESOC' (Serial of Champions ext)
unknown
****'flag' (Network Extension ext)
gestaltFlagshipAttr (not documented at all, see also TN311)
gestaltFlagship = 'flag'; *3
gestaltFlagshipPresent = 0; *3
gestaltFlagshipRegistered = 1; *3
****'fpu ' (System)
gestaltFPUType (addition)
gestal68040FPU = 3; *2
****'fs ' (System)
gestaltFSAttr (addition)
gestaltHasFileSystemManager = 2; *2
****'font' (System)
gestaltFontMgrAttr (addition)
additional System 7.1 responses exist but unknown
****'hdwr' (System)
gestaltHardwareAttr (additions)
gestaltHasRBV = 2; (RBV) *3
gestaltHasOSS = 5; (OSS) *3
gestaltHasSCSIDMA = 6; (53C80 SCSI DMA) *3
gestaltHasSWIMIOP = 8; (SWIM IOP) *3

gestaltHasDAFBVideo = 23; (DAFB Video) *3
****'He20' (Helium cdev)
unknown
****'hgfd' (AppleShare File Server appl)
gestaltAppleShareFServerAttr (not documented at all)
gestaltAppleShareFServer = 'hgfd';
gestaltAppleShareFServerPresent = 0; (present = running, selector
exists when appl has ran,
if still running bit is set)
****'icmp' (System?)
unknown ("integrated circuit map"?????)
below is what I guess at this moment:
gestaltSIMMICPresent = 'icmp'
gestaltSIMMICBankA1 = 0; (First two SIMMs in Bank A)
gestaltSIMMICBankA2 = 1; (Last two SIMMs in Bank A)
gestaltSIMMICBankB1 = 2; (First two SIMMs in Bank B)
gestaltSIMMICBankB2 = 3; (Last two SIMMs in Bank B)
etc. ... ???
****'Intj' (Interjection ext)
unknown
****'kbd ' (System)

gestaltQuadra700 = 22; *1
gestaltClassicII = 23; *1
gestaltPowerBook100 = 24; *1
gestaltPowerBook140 = 25; *1
gestaltQuadra950 = 26; *1
gestaltPowerBook145 = 45; (7.1, with 7.0.1 = 25) *4
****'mtcp' (MacTCP [>=1.1?] cdev)
returns noErr when present, return value is zero.
****'mmu ' (System)
gestaltMMUType (addition)
gestalt68040MMU = 4; *2
****'MV10' (TearOFF cdev)

****'ppc ' (System)
gestaltPPCToolboxAttr

gestaltPPCToolboxRTDeliv = 12; (supports real-time delivery) *3
gestaltPPCToolboxStore = 13; (supports store and format) *3
gestaltPPCToolboxCare = 14; (supports "Don't care") *3
contradiction: TN129 says "gestaltPPCToolboxPresent = 0;"
GestaltDA says "gestaltPPCToolboxDenyIn = 0;"
