cowdog360 Posted August 19, 2016 Share Posted August 19, 2016 Just a quick question here. How long can the Lynx II stay turned on while idle on AC? I swear I've had some that stay on nearly forever, and some that shut off after an hour or so. I know the Lynx I is different than the Lynx II in that regard. Any ideas? Thanks!

cowdog360 Posted August 19, 2016 Author Share Posted August 19, 2016 I'm actually wondering if this is a game/software issue. APB seems to shut off after an hour or two of idle time. I'm doing comparisons right now with two Lynx IIs and the diagnostic cartridge. So far they've both been on AC for about 1 hour 30 minutes. Any ideas if certain games shut the system down after too much idle time? Quote Link to comment Share on other sites More sharing options...
Level42 Posted August 19, 2016 Share Posted August 19, 2016 (edited) [AC connected] is fixed to +5V through a 100K resistor on Lynx II so it doesn't actually know if AC is connected or not.... So if it turns off, there has to be a software timer. Edited August 19, 2016 by Level42 Quote Link to comment Share on other sites More sharing options...
cowdog360 Posted August 19, 2016 Author Share Posted August 19, 2016 Just verified. With the Lynx diagnostic cart, I had it running for 3.5 hours on two identically modded Lynx II's. Then I booted Warbirds and left it on the title screen. Both turned off after an hour. APB does the same thing. So it has to be a game thing.

Level42 Posted August 19, 2016 Share Posted August 19, 2016 It couldn't be anything else really With the LTC2950 you could bring back the Power off after 4 minutes I guess....I don't think Atari changed the chipset between Lynx I and II.....

Level42 Posted August 21, 2016 Share Posted August 21, 2016 (edited) I just figured I could actually run this test on my Lynx I now too because I have the AC connected and Power On signals "disabled" (for now)..... I don't have APB and Warbirds on cartridge but I'll run them from the SD card. Edited August 21, 2016 by Level42 Quote Link to comment Share on other sites More sharing options...
Level42 Posted August 22, 2016 Share Posted August 22, 2016 Hey Cowdog, ran the test. Used Warbirds from SD card and set a timer. I measured Power on (inverted) after about 1 hour and 15 minutes and it was low, so yes, the game tried to turn the Lynx off.... Quote Link to comment Share on other sites More sharing options...
Glen's Retro Show Posted August 24, 2016 Share Posted August 24, 2016 Great job guys Quote Link to comment Share on other sites More sharing options...
Level42 Posted September 27, 2016 Share Posted September 27, 2016 Something interesting I noticed: Loderunner will not turn off the Lynx I after 4 minutes when idle on batteries.........so.....either there is some counter being reset in Loderunner or.....all the "official" games had the 4 minute timer built in....
