; ZCPR33 is copyright 1987 by Echelon, Inc.  All rights reserved.  End-user
; distribution and duplication permitted for non-commercial purposes only.
; Any commercial use of ZCPR33, defined as any situation where the duplicator
; recieves revenue by duplicating or distributing ZCPR33 by itself or in
; conjunction with any hardware or software product, is expressly prohibited
; unless authorized in writing by Echelon.
;
; This is a special version of Z3BASE, inspired by Joe Wright's Z3BASE
; for Z-Com.  All segment addresses are automatically derived when the
; CCP equate is set.  The benefit of this is that reconfiguration of the
; system after initial installation is greatly eased.
;
; Although this version of Z3BASE is being distributed with ZCPR 3.3, any
; previous version of Z3BASE can be used to assemble the Z33 Command
; Processor.  No new symbols are needed.  So, if you have an existing
; Z3BASE, go ahead and use it.
;
; Instructions:
;
; The user should first design the ZCPR3 memory usage using the chart
; below.  (Echelon recommends the chart be filled out, even though it is
; not read by the assembler, so that your system will be self-documenting.)
; Then set the CCP equate for the beginning address of ZCPR3.  Next, examine
; and change the SEGn equates which follow in the file to ensure that the
; system segments and buffers are placed at the proper addresses.
;
; This file has been customized for use with AMPRO hard disk systems.  The
; target configuration has support for hard disks up to 49 Meg, extended
; IOP support, and 28-entry NDR.
