mckafka99 Posted February 9, 2015 Share Posted February 9, 2015 You could try running a metal screwdriver along the cart edge connector..... Is that some kind of secret code / backdoor we haven't heard about? lol! Quote Link to comment Share on other sites More sharing options...
+Stephen Posted February 9, 2015 Share Posted February 9, 2015 You could try running a metal screwdriver along the cart edge connector..... I tried this, and the Jag just went to a black screen and now it won't boot with the Skunk (or any cart for that matter). Do you think it was because I used a Phillips instead of a flat blade? I'd like to get this up and running again. 4 Quote Link to comment Share on other sites More sharing options...

Philips screwdrivers are only recommended for use on the CDi's FMV adapter, its not compatible with Atari. 5 Quote Link to comment Share on other sites More sharing options...

I'm not going to suggest you go put it in the deep freeze - that would be silly - but how big is the ice box on your refrigerator? I've heard wonderful things.

DJ Vollkasko Posted March 8, 2015 Share Posted March 8, 2015 Well interestingly enough this thread sparked conversations at this years EJagfest. There was one known method to get external input into the Jag CDs VLM but it needed modding and extra hardware and a CD in the Jag CDrom: http://www.audiovisualizers.com/toolshak/vidsynth/jag_vlm/jag_vlm.htm Now what many may not know (and I didn't either until a kind soul told me about it at Jagfest) is that Glenn Bruner wrote a paper about Music Driven Graphical Visualization System which turns out to be a cartridge for the Jaguar with the VLM1 on it that allows external input!!!!! http://digitalcommons.calpoly.edu/cgi/viewcontent.cgi?article=1168&context=eesp Now this is exactly what I pictured. Imagine how cool it would be. You could just use your computers or even phone playlist and have the beautiful VLM1 without the need of a CDrom or even a CD not to speak of the modding mentioned for the CD Rom above. Just a cartridge. And if the issue could be fixed with not being able to save the selfmade effects, it would be even better than the original and we could all alter the 81 effects. (I used to record my effects on VCR but that is about 19 years ago or something and I don't have a vcr anymore ) The paper is from 2012. Now Glenn, how are our chances for you to produce this beautiful device for us? Sounds very fascinating! Any chance? If technically possible, an "AVM cartridge"/mod for 2600 would be neat, too.

Now Glenn, how are our chances for you to produce this beautiful device for us? That is interesting you guys found my senior project report. I had been wanting to build that for years and when it came time to finish my degree I saw working on external VLM as part of my senior project was a good opportunity. The one I ended up building and got working unfortunately uses an obsolete Philips chip. I was able to procure some from China but not very many of them. I had found another chip that I initially wanted to use because it was in production - but it did require the addition of a 3.3V regulator to the cartridge and logic level conversion from the 3.3V logic levels to TTL/CMOS. I was still learning about how to do PCB layout and get analog and digital circuits separate from each other and connecting their grounds. My first design was a horrible mess with all of the noise - digital dogs and analog cats don't get along with each other! I reverted to the Philips chip because it works with the 5V power and logic levels. A fellow student help me with getting a ground plane added to the board to help with the noise immunity. My biggest dilemma would be getting cartridge PCB's made. It is not cheap to have done. I was using Advanced PCB while I was a student which allowed me to take advantage of their very low pricing and fairly quick turn around.

It is not cheap to have done.If you can tolerate the delays, you can get your PCBs manufactured in China for reasonable prices.For example: https://www.seeedstudio.com/service/index.php?r=pcb 2 Quote Link to comment Share on other sites More sharing options...
