Re: best LCD monitor working with ATARI SCART

@catmando: it seems I have to build a specific VGA cable right? It's not a big deal, but is there a list with "SCART ready" monitors? ( so I don't have to build any cable?)

best LCD monitor working with ATARI SCART

Hi, My SC1424 monitor died few month ago. I tested an LCD TV with a SCART input I have at home. It worked, but colors are totally different in SCART mode with the ATARI. It's awfull! Did anyone know a good PC monitor reference, supporting a SCART input, and have decent color when used with a STE ? t...

Re: CosmosEx and 520 STm - Flipo Demo HDD

in your left log, almost all offsets are multiple of 256 ( $00 at the end ). this should not happen! ( right values are from the right log ). Maybe you should investigate on that. It's like cosmoex driver only reads multiple of 256 bytes?

Re: CosmosEx and 520 STm - Flipo Demo HDD

ok your binary dump seems ok. I just do another check: when I decompress the MSA file (when I load it) I check that no tracks is bigger than 5120 bytes ( if bigger I display "bad msa" file). If any track is bigger than 5120bytes it's certainly because of bad MSA decompression Are you aware...

Re: CosmosEx and 520 STm - Flipo Demo HDD

As I said in my previous post this is a basic check: just compare first values of MSA to ensure it's a 10 sectors, 2 sides, 81 or 82 cylinders. But if your MSA is working with emulator, the check is ok and your image is ok too :) that's why I don't understand. The only way is to trace the code and l...

Re: CosmosEx and 520 STm - Flipo Demo HDD

I can't debug it myself. I guess someone already runs the demo with cosmoex. What's the difference with your ST? what do you mean by "STm" ? Is it a STE?

Re: Best emulator for debugging

I'm surely not very objective but you can use SainT for sure! Personnally I did all my ATARI coding with SainT ( assembling on PC, my tools generate my demo in MSA format, and I run SainT). I wrote and debug all "We Were @" demo using SainT and my PC toolchain. Anyway Steem is really cool....

Re: CosmosEx and 520 STm - Flipo Demo HDD

looks strange. first message means that the file itself is not found. (I use a findfirst with "flipo*.msa" to find either flipo.msa or flipo_p.msa) the second case means that MSA file is not a flipo demo. The test is really basic, it just check MSA header to see if it's 2 sides, 10 sectors...

Re: ATARI HDD low level info

Just put the PRG in the same directory of any flipo MSA file ( original MSA or my patched MSA ), and enjoy :) http://leonard.oxg.free.fr/SainT/Flipo_HD.prg If you don't have the MSA, you can get ...

Yes could be fast but I really needed almost 0% cpu in my music driver, because of all effects Player take an average of 1/3 of raster line. Unfortunatly no re...

Internal power supply compatibility

Hi, I have a ATARI STE ( 4MiB ), and my internal power supply is really weird: my STE switch off automatically quite often. To switch it on again, I have to "press" the power supply metal casing a bit! (gasp) A friend of mine will trash its 520 STF. question: do you know if the power suppl...

Re: ATARI HDD low level info

I think I can go like that: GGN told me it's safe to keep using GEMDOS file system if I use only memory at $10000 and more. So I will review the memory layout of the demo,I have plenty of room in the 4MB version. I think I'll keep $8 to $10000 for system. My kernel will go from $1000 to top of memor...
