; Z3BASE - Dynamic Configuration
|
||
;
|
||
; 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.
