;*  ZCPR3 BASE EQUATES
;*

;
;  1. VERSION NUMBERS, MEMORY SIZE, and CP/M BASE ADDRESS
;
;	The following equates define the version numbers of the ZCPR3
; Command Processor and the CBIOSZ.  They also explicitly state the size
; of the TPA for inclusion in the CBIOSZ header printed at Cold Boot.
;
Z3REV	EQU	30	; ZCPR3 REV NUMBER
CBREV	EQU	41	; CBIOSZ REV NUMBER
MSIZE	EQU	52	; SIZE OF TPA
;
;    BASE - Base Address of user's CP/M system (normally 0 for DR version)
;           This equate allows easy modification by non-standard CP/M (eg,H89)
;
BASE	EQU	0

;
;  2. PROCESSOR SELECTION
;
;	The following equate selects the use of the 8080/8085 micro or
; the Z80 micro for the target for ZCPR3.  Note that selecting the
; 8080/8085 should be done ONLY if you have an 8080 or 8085.  If you have
; a Z80, by all means select this one since the code is much smaller and
; you can cram more features into the system as a result.
;	If the processor is an 8080 or 8085, set this equate to TRUE.
; If the processor is a Z80, set it to FALSE.
;
I8080	EQU	FALSE

;
;  3. EXTERNAL PATH
;
;	The following equates define the address of the ZCPR3 External
; Path and the number of two-byte elements contained in this path (maximum).
; If there is no ZCPR3 External Path, both of these values should be set to 0.
;
EXPATH	EQU	40H	; EXTERNAL PATH
EXPATHS	EQU	5	; 5 2-byte Path Elements
			;  (PATH SIZE = EXPATHS*2 + 1)

;
;  4. WHEEL BYTE
;
;	The following equate defines the address of the ZCPR3 Wheel Byte.
; If there is no ZCPR3 Wheel Byte, this value should be set to 0.
;
Z3WHL	EQU	4BH	; WHEEL BYTE ADDRESS


;
;  5. CCP LOCATION
;
;	The following equate defines the address of the ZCPR3 Command
; Processor.  This address MUST be supplied.
;
CCP	EQU	0D000H	; ZCPR3 COMMAND PROCESSOR


;
;  6. RCP LOCATION
;
;	The following equates define the address of the ZCPR3 Resident
; Command Package and its size in 128-byte blocks.  If there is no
; ZCPR3 Resident Command Package, both of these values should be 0.
;
RCP	EQU	00000H	; RESIDENT COMMAND PACKAGE
RCPS	EQU	00	; 00 128-byte Blocks (0K bytes)


;
;  7. IOP LOCATION
;
;	The following equates define the address of the ZCPR3 Input/Output
; Package and its size in 128-byte blocks.  If there is no ZCPR3 Input/Output
; Package, both of these values should be 0.
;
IOP	EQU	00000H	; REDIRECTABLE I/O PACKAGE
IOPS	EQU	00	; 00 128-byte Blocks (0K bytes)


;
;  8. FCP LOCATION
;
;	The following equates define the address of the ZCPR3 Flow Command
; Package and its size in 128-byte blocks.  If there is no ZCPR3 Flow Command
; Package, both of these values should be 0.
;
FCP	EQU	00000H	; FLOW COMMAND PACKAGE
FCPS	EQU	0	; 0 128-byte Blocks (0K bytes)


;
;  9. ENV LOCATION
;
;	The following equates define the address of the ZCPR3 Environment
; Descriptor and its size in 128-byte blocks.  If there is no ZCPR3 Environment
; Descriptor, both of these values should be 0.
;
Z3ENV	EQU	0F400H	; ENVIRONMENT DESCRIPTORS
Z3ENVS	EQU	2	; SIZE OF ENVIRONMENT DESCRIPTOR IN 128-BYTE BLOCKS


;
; 10. SHELL STACK
;
;	The following equates define the address of the ZCPR3 Shell Stack,
; the number of entries permitted in the ZCPR3 Shell Stack, and the size
; of each entry in the Shell Stack in terms of bytes.  If there is no ZCPR3
; Shell Stack, all three values should be 0.
;
SHSTK	EQU	0F500H	; ZCPR3 SHELL STACK
SHSTKS	EQU	4	; NUMBER OF SHSIZE-BYTE SHELL STACK ENTRIES
SHSIZE	EQU	32	; SIZE OF A SHELL STACK ENTRY
			;   (STACK SIZE = SHSTKS * SHSIZE)


;
; 11. ZCPR3 MESSAGES
;
;	The following equate defines the address of the ZCPR3 Message Buffer.
; This buffer is always 80 bytes long.  If there is no ZCPR3 Message Buffer,
; this address should be 0.
;
Z3MSG	EQU	0F580H	; ZCPR3 MESSAGE BUFFER


;
; 12. EXTERNAL FCB
;
;	The following equate defines the address of the ZCPR3 External FCB.

			;   (NDIR SIZE = Z3NDIRS*18 + 1 for trailing 0)


;
; 14. COMMAND LINE
;
;	The following equates define the address and size (in terms of bytes)
; of the ZCPR3 Command Line Buffer (formerly called the Multiple Command Line
; Buffer under ZCPR2).  If there is no such buffer, both of these values should
; be 0.
;

Z3CLS	EQU	200	; SIZE OF COMMAND LINE BUFFER


;
; 15. EXTERNAL STACK
