That is most probably a linear type. Usually, they are pretty simple to fix. The transformers (the most expensive part) is pretty reliable. I would look at the main power caps and maybe the output pass transistor(s). You can probably get that unit working again for just a few bucks.
The thing about modding computer PS units is that they are all different. The modding scheme is the same (and usually pretty easy to do), but the details will vary.
Edit: I just checked, that motorola PS is rated for ~ 10A @ 14v. You may have just been pushing it too hard for too long. You sure you just don't have a blown fuse or something simple?
