Finally got the Quadra 650 hooked up, but she's not doing too well. Trying to get her to boot up to Mac OS, but had to use the optical drive to do so, and barely at that. Trying to see what to clean things up as best I can.

I may have to look into buying a soldering iron very soon. 

Welp, for sure the SCSI hard drive is shot. Doesn't want to boot up at all, and isn't even detected anymore. Shame, because I had some files in there, but most of them were just apps which I have elsewhere. I did have a SCSI to IDE adapter somewhere, so I could possibly toss an IDE hard drive in there. Some of these laptops ones here should work fine if I can find the adapter.
@mmarcott For sure, but I need money for that.
