khryssun Posted January 14, 2013 Share Posted January 14, 2013 Hi there, It's been years since my last visit... and oh god, there are so many wonderful new things here. Harmony looks realy fantastic and I can't wait to get one. But I'd like to know if I'll be able to use the Harmony cart with my modified 7800 (Eckhard Stolberg DevOS 0.2) without problems? (I lost the original 7800 BIOS ROM... I know I'am unforgivable). I've got another question related to the Harmony's Paypal order page: it's undergoing maintenance for more than 24 hours now, any idea when it will be operative? I visited this page for the first time yerterday, so maybe it lasts for longer? Anyways, I hope it will be back soon. Glad to be back. Thanks in advance for your answers. Cheers, Chris Quote Link to comment Share on other sites More sharing options...

LidLikesIntellivision Posted January 14, 2013 Share Posted January 14, 2013 What is a DevOS? I have a modded american 7800 with the Asteroids built-in and no Atari logo. Is this the DevOS or just the european Rom without the atari logo? Quote Link to comment Share on other sites More sharing options...
roland p Posted January 14, 2013 Share Posted January 14, 2013 It's a different OS made for loading roms through the joystick port (connected to your computers parallel port) and save them on a cart with ram iirc. Quote Link to comment Share on other sites More sharing options...

Thanks for the answer. Really cool to load a game from the joystick port! Quote Link to comment Share on other sites More sharing options...
Dauber Posted January 15, 2013 Share Posted January 15, 2013 I'd say, as long as your 7800 can play 2600 carts, the Harmony should work, modified OS or not...that's my guess... Quote Link to comment Share on other sites More sharing options...
shadow460 Posted January 15, 2013 Share Posted January 15, 2013 What is a DevOS? I have a modded american 7800 with the Asteroids built-in and no Atari logo. Is this the DevOS or just the european Rom without the atari logo? Dev OS has the capability to dump ROM images from both 7800 and 2600 carts into binary format. It also allows you to load bin files into a RAM cartridge for use on a 7800. I am told it gives the 7800 a very limited capability to burn EPROMS, but I have never done this. It's primarily a development tool. Quote Link to comment Share on other sites More sharing options...
khryssun Posted January 15, 2013 Author Share Posted January 15, 2013 (edited) Thank you all for your answers. I hope the Paypal's payment option will be back soon. For those who are curious about the devOS, here's the link to Eckhard's tools page : http://home.arcor.de...ools/index.html Cheers, Chris Edited January 15, 2013 by khryssun Quote Link to comment Share on other sites More sharing options...
