; z3base.fp -- B/P Bios System Z3 Definition File for not or partially
;		banked system with 512 byte external HBIOS proxy (no
;		internal proxy).

; This file is adapted from the basic Z3BASE.LIB configuration file used for
; most ZCPR33 systems.  It has added the new definitions for the Resident
; User Space defined in B/P Bios descriptions and modified for an HBIOS
; implementation with a full external HBIOS proxy (i.e. proxy not internal
; to BPBIOS).
;
;=========================================================================
;==   NOTE: The Starting Address of the User Space marks the lower	==
;==   base of memory and MUST be entered.  B/P Bios Utilities use	==
;==   this address to locate many portions of the operating system.	==
;=========================================================================
; To change your systems definition, first sketch out the memory map in the
; comment table, then set the equates to reflect the memory map, doing any
; required calculations for element sizes and required spaces.  As an
; alternative, just leave this file alone and configure everything with
; the utilities provided.
