DavidMil Posted January 27, 2017 Share Posted January 27, 2017 Are the 830 and 835 power supplies the same (under the hood) with different parts numbers and text on the outside? If memory serves me correctly, they were about the same size and shape and had the same size connectors. DavidMil Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted January 28, 2017 Share Posted January 28, 2017 (edited) It looks as if it will work. Look here: http://atariage.com/forums/topic/178588-atari-835-power-supply/?do=findComment&comment=2231698 Edit: Also read the message below the one linked above.

DavidMil Posted January 28, 2017 Author Share Posted January 28, 2017 This was a long time ago but I remembered that my old 830 had a 24 volt power supply. Anyway, I was looking online when I came across a article in Atarimania that showed that there were two power supplies for the 830. One was 24volts @150mA 3.6VA (CA016751), and the other was 20Volts @ 400mA 8VA. The 835 fits right in between there: 20Volts @ 330mA 6.6VA (CO60479) & (CA060535).

fujidude Posted January 28, 2017 Share Posted January 28, 2017 (edited) Keep in mind modern computer power supplies provide a +12 and a -12V DC, so if you wire across them you get 24V DC. And older ones still even had a -5V DC (in addition to the +5V DC). Edited January 28, 2017 by fujidude Quote Link to comment Share on other sites More sharing options...

I understand what you are saying , it's the similar to the way we get 240volts AC (off of two 120v legs that are 180 degrees out of sync). Did you post this on the wrong thread or maybe I didn't make it clear that we are talking about little 9Volt AC power supplies. Nothing to do with DC.

Nothing to do with DC. See (your post) #3 above. 24V was interjected into the conversation at that point. I was just responding to that thinking you were referring to 24V DC (you didn't specify AC or DC). I didn't have something to offer on the 9V AC right then, but thought a quick foot note about that would be alright. That's all. Quote Link to comment Share on other sites More sharing options...

fujidude Posted January 30, 2017 Share Posted January 30, 2017 My fault. Sorry, David Milsop I can't see any fault or anything to be sorry for... I have a habit of putting forth more information than perhaps is necessary anyway. Quote Link to comment Share on other sites More sharing options...
