cbmeeks Posted April 2, 2016 Share Posted April 2, 2016 (edited) I just bought an original 520 ST for $29. It needs some cleaning and painting that I'm doing now. Original owner spilled red paint all over it!! Anyway, it didn't come with a power supply so I have no way to test it. My other ST's either don't have power supplies or they have them internal. This ST is the first. I'd rather use a modern PSU if I could. Anyone know where I can get something new or perhaps on how to build one? I have reasonable eletronic skills and can solder, etc. Thanks.

Here you go http://retrospec.sgn.net/users/tomcat/miodrag/Atari_ST/Atari_ST.htm look about half way down the page. You will need a Din 7 I actually installed a PicoPsu in my 520st its small enough that it fits Edited April 2, 2016 by goaltoss Quote Link to comment Share on other sites More sharing options...
galax Posted April 3, 2016 Share Posted April 3, 2016 You may be able to get away with supplying just the 5v, the +/- 12v seems to only be needed for the RS-232 port: http://www.atari-forum.com/viewtopic.php?t=28472 Quote Link to comment Share on other sites More sharing options...
