contiki

Contiki OS for the C64 comes in three formats:

Three 171kB 1541 disk images (contiki-c64-1.d64, contiki-c64-2.d64 and contiki-c64-3.d64).
One 342kB 1571 disk image (contiki-c64.d71).
One 800kB 1581 disk image (contiki-c64.d81).

All five disk images are contained in the contiki-c64.zip file.

Contiki OS for the C64 supports the RR-Net and the ETH64 Ethernet devices.

By default a standard 1351 mouse is supported. By renaming an alternative mouse driver to CONTIKI.MOU a different mouse can be supported (INKWELL.MOU for an Inkwell Systems lightpen, JOY.MOU for a standard joystick, e.g. a 1350 mouse and POT.MOU for a potentiometer device, e.g. a Koala Pad).
