After further inspection of the photos I took, I can definitely say that C101 and C105 will need to be redone as they look the worst out of all of them.

What’s really weird about it is that the model number on the bottom is M1476 which is the model number for the LC 475. I tried to find clues by searching the hard drive (when the computer would boot) but it was pretty well cleaned out. At some point, someone must’ve swapped the floppy drive and...

Good news! The floppy drive fits and it looks identical to the one in the IIcx although the motorized eject mechanism looks slightly revised. I decided I should probably give some backstory on the LC 475. the LC 475 I have is a little strange. In fact, it was being sold as an LC III because for...

Thanks for the encouragement. I’ll let it rest for a while then come back to it like you said. In the mean time, at least I can make use of its floppy drive in my IIcx. One more question. In the future, should I continue to use electrolytic caps for replacement or ceramic caps?

Honestly, this project is becoming more trouble than it’s worth, and I may just sell the individual parts and put the money toward a 68040 accelerator card for the IIcx. On the plus side, at lest I can use the floppy drive in the IIcx. I didn’t pay too much for it so it’s not a huge loss...

Looking at these photos myself, I didn’t realize just how bad it all looks. This is by far the worst job I’ve ever done with SMD.

I decided to put the board into the dish washer. Once it’s out and dried off, I’ll take some pics of everything. I don’t know if this info helps, but my method of installing the new caps was solder paste and a hot air reflow station.

Just now recapped the PSU no difference. Although, when powered off, the clicking lasts longer.

I got all the caps installed and redid the jumper wire solution. Unfortunately, the power supply decided to quit. I made the mistake of opening it to check the caps. They looked good so I put it back together. I must’ve done something wrong however, because now the power supply just makes a...

Alright I now have the other end on the bottom side of the board. The reason I have it wrapped around is for extra durability.

Good point. Would something like this work?

Can I use the cover on the ADB, serial, or printer port as a ground if I have a long enough wire?

Yup. It was set to F. And yes I was indeed struggling to melt solder. It melted the flux just fine although I guess that’s to be expected. I will be sure to use 572F in the future. This is my second time doing this sort of project, so I’m still a beginner and I appreciate the help :-). I don’t...

Another quick question, for future reference, what temperature should I set my hot air station to for desoldering/soldering? 370F is what it was set at when I tore up the pad.

At the moment my problem is my equipment. All I have is a hot air station and a cheap Walmart soldering iron. The hot air station works great when all goes according to plan especially since I use solder paste. However for doing small repairs that wouldn’t work great with the hot air station...
