|
|
; The purpose of this file is to define generic symbols and to include
|
|
; the appropriate std-*.inc file to bring in platform specifics.
|
|
|
|
; There are four classes of systems supported by N8VEM.
|
|
; 1. N8VEM Platforms that include ECB interface
|
|
; 2. ZETA Genrally N8VEM-like, but no ECB
|
|
; 3. N8 Generally N8VEM-like bt 180 and extra embedded devices
|
|
; 4. S100 Assumes Z80 Master CPU Card
|
|
|
|
; All the classes require certain generic definitions, and these are
|
|
; defined here prior to the inclusion of platform specific .inc files.
|
|
|
|
; It is unfortunate, but all the possible config items must be defined
|
|
; here because the config gets read before the specific std-*.inc's
