+Contiki on the Apple ][ (Oliver Schmidt)
+========================================
+
+To make as much as possible memory available to Contiki the DOS 3.3 (clone)
+used for loading Contiki into memory will be overwritten on Contiki startup.
+
+Contiki requires DOS to be moved into language card (bank 2). It has been
+successfully tested with:
+
+- DavidDOS with HIDOS
+- DavidDOS II with HIDOS
+- DiversiDOS with DDMOVER
+- 64k DiversiDOS
+
+With the 'a2tools by Terry Kyriacopoulos' you use the following commands to
+insert Contiki into an (already existing) DOS 3.3 (clone) dsk image file:
+
+a2tools in    t contiki.dsk CONTIKI.TEXT contiki.txt
+a2tools in -r b contiki.dsk CONTIKI.CODE contiki.cod
+a2tools in -r b contiki.dsk CONTIKI.DATA contiki.dat
+
+On the Apple ][ enter the following commands on the Applesoft prompt (']') to
+create the Contiki startup program.
+
+NEW
+EXEC CONTIKI.TEXT
+SAVE CONTIKI
+
+Contiki uses the follwoing keys:
+
+toggle menu: ESC
+next widget: TAB
+prev widget: CONTROL-A
+next window: CONTROL-W
+
+eof
