; *** 6.0.1 ***
;
; 15-Dec-92 DAL for 6.0.1d12
; Changed apple_cd version number to $601a.
;
; 17-Feb-93 JCM for 6.0.1d14
; Changed direct_acc, mcd_40, scanner and appl_laser (for good measure anyway)
; version numbers to $601a.
;
; 6-Mar-93 JCM for 6.0.1d14
; Added equate for new characteristics bit ($0010) called "driver_is_clean".
; This indicates that we cleanly ignore/return errors when we get a command
; request from GS/OS or the Device Manager that we don't know about. This was
; specified in the guidelines since day one, but can people read and follow them?
; Of course not, that would make my job too easy.
;
; 2-Apr-93 SS for 6.0.1d16
;
; Changed direct_acc, apple_cd, mcd_40, scanner and appl_laser
; version numbers to $6010 (final)
