Hey all! I'm a completely new poster here, but I thought I might be able to add something...
I bought my first Saturn about a week ago, and last weekend I turned to modding it (installing a 50/60 Hz switch and a three region switch), planning on mainly using the method described at
http://www.mameworld.net/pc2jamma/satmod3.html (it involves building a small circuit with an hex inverter to control the jumpers) It soon turned out that my motherboard was of the type that has two of the three jumpers needed for region modding on one side, and another one on the other side of the board (croft was kind enough to post a 50/60 Hz modding guide earlier in this topic using the same board model). Now, being a complete newbie when it comes to soldering and the like, this kind of freaked me out. GameSX.com's modding guide didnt help much either, since my Saturn was just about the only version where they didn't have any good pictures of the jumpers.
Anyway, using a multimeter I soon figured it out (one of the jumpers, the "lone" one, is actually reversed!), and I made sure to document more or less the whole process using my digital camera, taking some real closeups along the way. I also took some closeups of the 50/60 Hz mod. I was going to offer these images to GameSX, but I was just wondering if anybode here is interested. I learned
a lot doing this mod, so I think I should be able to answer a few questions as well, if anyone has any.
Oh, and how did the modding go? Excellently! My Saturn works like a dream now, and I also think the installation turned out rather nice for someone who has never ever done anything like this before.
So, anyone interested in these images? I don't have any space to host them on ATM, unfortunately...
