+remowilliams Posted June 15, 2009 Share Posted June 15, 2009 Sorry about the Delay guys. the amiga version is complete but the atari version we are having some trouble with (has to do with the V-sync H-sync Conversion to C-sync) I've had a few annoying issues myself in that area. Including one which lead to my MSTE having the double VBL or 'twinsync' issue, that drove me absolutely bonkers for a bit. Quote Link to comment Share on other sites More sharing options...

Kjmann Posted June 17, 2009 Author Share Posted June 17, 2009 (edited) UPDATE: We've run into a problem with the Sync issue in the adapter. It seems to work on some ST's and not others. the Sync signals in an ST seem to vary depending upon what unit (what year and run of units it came out of) that a person has. It has something to do with the double VBL or 'twinsync' issue that Remo was taking about. we are not sure what to do about it or if it can be over come. It's seems to be very random as to which ST a person has. The only way we can see to be sure that the unit will work for anyone that buys one is to require the ST to have a Modulator in it. I'm still thinking about this decision. let me know what you all think. Edited June 17, 2009 by kjmann Quote Link to comment Share on other sites More sharing options...
+Allan Posted June 17, 2009 Share Posted June 17, 2009 Well, other RF equipped STs, is there any way to tell if an ST will work with it, even if you have to open one? I definately want one. Luckily my ST has an RF adapter. Allan Quote Link to comment Share on other sites More sharing options...

I definately want one. Luckily my ST has an RF adapter. Allan No. Unfortunately there is no way to tell if a person has one that will work. so if we change the requirements to include an RF equipped ST then we can be sure that customers that are buying it will not have to worry about whether or not it will work.

Goochman Posted June 18, 2009 Share Posted June 18, 2009 So bascially the 1040ST and Mega ST owners are out of luck? - That is prob the majority of units sold (atleast in the US). Quote Link to comment Share on other sites More sharing options...
Foster Posted June 18, 2009 Share Posted June 18, 2009 I've got ST's with and without RF so I'm in either way. I can understand the disappointment from those lacking RF though. Quote Link to comment Share on other sites More sharing options...
Kjmann Posted June 18, 2009 Author Share Posted June 18, 2009 Believe me. If we can release this with out an RF requirement, we will. Does anyone know if piping the H-Sync and V-Sync through an LM1881 would help our problem? Quote Link to comment Share on other sites More sharing options...
Goochman Posted June 18, 2009 Share Posted June 18, 2009 Would it be ok to offer us 1040/Mega ST owners the ability to test/return (Video 61?) - Of course Id pay for return shipping if it didnt work. Any easy way to add RF Mod to a Mega ST 2? Quote Link to comment Share on other sites More sharing options...
KLund1 Posted June 18, 2009 Share Posted June 18, 2009 Perhaps add an additional circuit, and rocker switch for ST's with and without modulator installed? It would terrible to exclude a huge population for ST users that don't have the 'right' ST. Also, in it's current state will it work for MSTE?

+remowilliams Posted June 18, 2009 Share Posted June 18, 2009 Does anyone know if piping the H-Sync and V-Sync through an LM1881 would help our problem? I didn't get far enough down the road to investigate ICs, but I'd hazard a guess that there is one that could help out. If you can prevent the twinsync issue on affected models, an H+V combined CSYNC should work on all the STs. Quote Link to comment Share on other sites More sharing options...

cfernan Posted June 20, 2009 Share Posted June 20, 2009 For the Atari ST with modulator RF already there exist several types of cables that allow to connect to monitors VGA and TV. The problem is for that we have Atari without RF: will not we have solution? Quote Link to comment Share on other sites More sharing options...
Forrest Posted June 20, 2009 Share Posted June 20, 2009 Many years ago when I was learning how to connect an Atari ST with a Sony KV20-XBR monitor (an RGB monitor with composite sync), I found the solution to connect the two was fairly simple. It involved connecting Hsync and Vsync with a switching diode and one or two resistors. Sorry I don't have the exact schematic - but I used this cable for years with a MegaST (no RF modulator).

Forrest Posted June 21, 2009 Share Posted June 21, 2009 I didn't want to hijack this topic, so I've uploaded the Sony cable article separately under it's own topic. Hopefully it's useful to someone. Quote Link to comment Share on other sites More sharing options...

We're still working on it. we keep running into a problem with the Sync signals. not sure why but they don't seem to be compatible with the decoder chip that we have used.

desiv Posted September 3, 2009 Share Posted September 3, 2009 We're still working on it. we keep running into a problem with the Sync signals. not sure why but they don't seem to be compatible with the decoder chip that we have used. No rush. Count me in. I picked up a 520ST, but hadn't researched them at all (as far as Video output) and it has no RF and I have no monitor. So it's just sitting. I'm also in Oregon so if you need another ST or testing or ??, just let me know.
