Coding C64 screensaver.
I did this easily on the Oric and I think this could be done on the C64 too.
The idea is simple - I have installed an interrupt which counts the time since the last keypress and if it's more than the configured - the screen goes black. Since the Oric have fixed text/graphic pages address - I had to copy the whole video memory to somewhere else and set black image, and copy it back when the screen is on again. On the C64 this can be accomplished more easily - you just save the color registers, set all them to black and then return them back when an event occurs. And there are sprites which you can use for flying toasters, chickenlips or similar. This could be of no use for the BASIC mode, but in contiki it might prove useful, but I know almost noting about this OS so I will say pass here.
Regards.
P.S. The screensaver is useful if you like me use an old tube-style monitor. For the modern lcds it's useless I believe. |

Watch that you don't blow your SID when toggling power on the monitor. If the sound goes to a separate amp, you're probably fine. |

Groepaz: you are completely right, but would be a nice addition for the ROM, just like the jingle, hm ?
Aehm .. just stumbled over the thread ... a little late as always :)
