;
; External command for Davex
;
; deschw -- describe hardware
;
; Options:
; -t system type
; -c cards
; -s SmartPort
;
; 15-Oct-89 DAL ==> v1.2
; Changed "//" to "II"
; Added IIc+ identification
; & fixed mismatched parens
; Added IIe debugger ROM id
;
;*********************************************
;
; Converted to MPW IIgs 20-Sep-92 DAL
;
;*********************************************
; 27-Jul-17 MAG ==> v1.3
; Added Apple IIe Card
; for Mac LC identification
; 28-Jul-17 MAG ==> v1.3 (still)
; Added CPU identification (6502, 65C02, 658xx)
; Added emulator identification
; Reduced repetition, reworded, saved a few bytes
; Fix bug where garbage is printed if smartport
; device name is 0 bytes long
; Fix AppleTalk identification & enhanced
; Fix case where an emulator doesn't execute
; missing SMB0 as two-byte opcode
; 05-Aug-17 MAG ==> v1.3 (still)
; Work around lazy IIe LC PDS Card SmartPort.
; 07-Aug-17 MAG ==> v1.3 (still)
; Show Smartport ID type info (Extended/SCSI/RAM card)
; Optional code to show SmartPort vendor and version (not working?) SmartPort TN #2
; Support additional devices defined in SmartPort TN #4
; Support subtype flags as described in SmartPort TN #7
; 14-Aug-17 MAG ==> v1.3 (still)
; Reduce emulator detection to actual emulator for those supporting
; EMUBYTE, or "probable" if no floating bus detected. If you want more
; specific identification, see idemu program.
