Yesterday evening I've browsed the web with my Atari for the 1st time :-) But I don't consider the port to the Atari ready yet. I made some serious hacks in the source to decrease the memory footprint. The selecton of programs is completely disabled and it jumps directly into the web browser. Among this I disabled the runtime configuration of the IP address and name server address. These addresses are currently hardcoded, so you need to recompile it to adapt it to your configuration :-( I'd like to have the runtime IP configuration included for a real Atari release. The current version loads at $2000 and uses memory up to $BAE4 (stack at $BC1F). So it doesn't work for e.g. Atari DOS 2.5 (lowest address available $244C with 4 drives), SpartaDOS works ($1FC0; addresses with R: handler for 850 loaded). I'm now looking into using some tiny loader DOS (MyPicoDOS, http://www.horus.com/~hias/atari/) where it could be loaded at $700 (w/o R: handler). But MyPicoDOS cannot yet load both the R: driver and then the contiki app. So I think I'll try to modify MyPicoDOS to load the R: driver by itself (should give some final load address at around $DC0 for contiki). Another idea is to get more memory by loading the 800 (not xl) BIOS into RAM which should make the area $C000 to $D000 available (not used by this BIOS), giving another 4k of RAM. If you're ready to compile your own version, I can send you my diffs for contiki-1.0. > Once its done, I'd be interested in programming some apps/utils for it! Looks very neat. The memory is very tight on the Atari, so it's not that straightforward... regards, chris ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo_at_musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.
