Change History (most recent first):
|
|
|
|
<SM7> 1/5/94 kc Add Function ProtoTypes to prevent compiler warnings.
|
|
<SM6> 12/13/93 PN Roll in KAOs and Horror changes to support Malcom and AJ
|
|
machines
|
|
<SM5> 9/2/93 SKH Roll in changes from Horror
|
|
<SM4> 2/11/93 CSS Remove boxflags from this file.
|
|
Update from Horror. Comments follow <H10-2>:
|
|
<H10> 1/21/93 RLE add Escher box flags
|
|
<H9> 6/30/92 ag Added new type definitions.
|
|
<H8> 5/7/92 ag Added new type definitions to accomodate table changes.
|
|
<H7> 4/24/92 ag added new hardware dependent field for general use by hardware
|
|
dependent code. added new typedefs to allow for easier type
|
|
conhersion.
|
|
<H6> 12/17/91 SWC Added boxDBLiteLC.
|
|
<H5> 12/16/91 HJR Added boxDartanian.
|
|
<H4> 11/5/91 SWC Fixed boxDBLite again because we got pushed out to a new value.
|
|
<H3> 9/10/91 SWC Fixed boxAsahi and boxDBLite to reflect final values.
|
|
<H2> 8/5/91 SWC Added boxDBLite to list of CPUs we work with.
|
|
<8> 3/30/92 JSM Rolled this file into SuperMario project.
|
|
<7> 3/24/92 JSM Nuke boxFlag codenames.
|
|
<6> 10/28/91 SAM Rolled in Regatta file.
|
|
|
|
Regatta Change History:
|
|
|
|
<7> 8/8/91 SAM (ag) Updated boxFlag constants in this file (yuk!)
|
|
<6> 7/30/91 SAM (ag) changed version to 1.0.2
|
|
<5> 7/18/91 SAM (ag) added box flag constants, changed global definitions
|
|
<4> 6/30/91 SAM Merged from TERROR [<4><5>].
|
|
<3> 6/14/91 SAM (ag) Added sample interval field to global definition.
|
|
<1> 5/15/91 SAM Split off from TERRORProj.
|
|
|
|
Terror Change History:
|
|
|
|
<5> 6/26/91 ag added support for table change as a function of charger and
|
|
voltage. New fields in global include slewing flags and rates,
|
|
procedure proc definition to call to handle table changes, and
|
|
voltage thresholds for hysteresis on table changes.
|
|
<4> 6/24/91 ag Added table pointer elements and other variables to global data
|
|
structure. Added new define for range set call.
|
|
<3> 6/10/91 ag Added sample interval field to global definition.
|
|
<2> 4/2/91 ag added definitions for globals.
|
|
<1> 1/23/91 ag first checked in
|
|
|
|
<5> 11/8/90 ag change range of backlight, max now 30
|
|
<4> 9/25/90 ag added asahi support
|
|
<1+> 8/15/90 ag adding get range function to status call
|
|
90/07/27 ag new today
