;*
;* 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.
;

; 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.

RCPS EQU 00 ; 00 128-byte Blocks (0K bytes)
;
; 7. IOP LOCATION
;

; Package and its size in 128-byte blocks. If there is no ZCPR3 Input/Output
; Package, both of these values should be 0.

;
; 8. FCP LOCATION

FCPS EQU 0 ; 0 128-byte Blocks (0K bytes)
;
; 9. ENV LOCATION
;

;
; 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.
