+********************************************************************
+* NitrOS-9 Memory Definitions for the Atari XE/XL
+*
+* The Atari's support chips have certain alignment restrictions for
+* things like screen memory, display lists and character maps.  For this
+* reason, we reserve some low memory for the screen.
+*
+* Screen memory range is $0500-$08FF (1K).  Of that, 40*24 (960) bytes
+* are for the screen buffer and the remaining 64 bytes are for the
+* ANTIC's Display List
+G.Cols         EQU       40
+G.Rows         EQU       24
+G.ScrStart     EQU       $0500
+G.DList        EQU       G.ScrStart+(G.Cols*G.Rows)
+G.DListSize    EQU       64
+
+* The Character Set must be aligned to a 4K address.  We can really only
+* guarnatee that in the Krn module, which is always at the end of RAM.  So
+* for now, the character set is located at $F800
+G.CharSetAddr  EQU       $F800
+
+* POKEY requires shadow registers.  We allocate them in the kernel's DP
+* (Yes, we are stealing an existing variable that is so old it should be
+*  removed from os9defs)
+D.IRQENShdw    EQU       D.WDBtDr
