This is a great thread. I have struggled with the boards with this design a lot. Very hard to test outside the body and they are so frail. I have a CC apart for a couple of years. Booted once. Recapped both boards. Nothing. I will definitely visit this one again. Thanks for the great...

the shipping charge is caused by the taffifs. I have purchased from him before and these are very good. Somewhere the guy posted about the $50.00 charge and the cause. Also, some people suggested a group buy to offset the tarrif cost as these weigh next to nothing. Anyway, I wouldn't blame...

Amazing job. I have been following and your patience is to be rewarded. A lot of great tips too. I have also found that having other working parts is a big plus in trouble shooting the problems. It sure takes time to collect the pieces, tools, and knowledge to do a successful repair like...

Well, idiot me. It was working all the time. I should have dragged folders over at the bottom of the FPD. The top is blocked as it should be. This thread and the pictures really got me thinking and now I am a happy camper.

Have and LC 580 with proven good analog board. Logic board was recapped by someone else and it was not pretty. Trying to trace it out but hoping for a schematic to help me. The computer does not power up with this logic board. I have struggled with a few of these boards with the edge...

Oh No!!!

Appreciate the info. I believe I have the same set up. I have been able to get the FP Display working but cannot run both screens at same time. My Display is a really early one. I also downloaded some software that may allow both screens to display but I think my ROM may be incorrect...

Thanks for that follow up @jmacz I actually bought that kit from Amazon. Have not put board in the tower yet but I think there is enough room. I also found more corrosion on the traces and the battery connections were bad too. I am a real amateur on trace repair but it all works so that is a...

I did not realize it was a two piece deal. I just took one apart. That helps a lot, just knowing that. Although I am missing one of them. So my problem is half solved. That being said, the ones on a 6100 bombed board may have good plastic stands so that may solve the problem. It is not that...

The battery took out the switches on the logic board. Are they common and avaible to purchase? the buttons in the case are fine but it is the switches on the board itself that I cannot find. I have another battery bombed logic board that uses the same switches but they really look...

Oh, it is booting but just not recognizing the card. I have also applied Deoxit in all the slots. Have not been able to get the software on a floppy yet. I also assume it needs to be running System 8 too. I have some final assembly work to do including mounting the floppy cable into the...

Gottcha. Great feedback. I know I need the heat sink. It was like a sacrificial anode and I think protected the card itself. I think I can make what's left of it useful if I can remove one of the screws that is really stuck in the card. I just want to see if I can get the computer to...

the battery bombed one came with a very corroded Newer Tech upgrade card. The heat sink was really bad and I removed it. I really cleaned the card and have just tried it in the unbombed machine. No luck recognizing it though. It would be destroyed for all I know. Do I need drivers for the...

(y)Runs great on both 7.6.1 and 8.6. I think it is good to go. Reassembling with various better pieces from a battery bombed one.

Cleaned up my recap job and found one very close to traces. Picture attached. I cleaned up and coated the traces with lacquer. Now running again. I have installed a BlueSCSI and for whatever reason it thinks it is ID 1. I set up the image as HD00.hda. It is working but I do not understand why...

Thanks. Not sure the boards are that similar. The pin goes to a via and I have not been able to trace yet.

Had a working 6100. I recapped and ISO cleaned. Now will not boot. I am probing what I believe is the egret chip and get signal all around except nothing on pin 7. A schematic would help or someone knowing where that pin goes. I have double checked all the caps I changed and am not finding any...

Thanks for the quick response. I really don;t want to part out the machine. Everything looks good except that part. First time I have run into that. For some reason the ground connectors to the lugs were missing. Not sure why. That is what made it loose.

Repairing an LC logic board with a bad 15 pin video connector. Can these be sourced or do I need to rob from a bad board? The only bad board I have is for a Quadra 700. Visually it looks slightly different. Do I need to find a bad LC board? Computer booted and runs fine. I was planning on...

Well, it only works in one direction so it is in correctly. I put the original expansion card in and it reads correctly. So I am starting to believe that maybe this card was never good. 2MB isn't bad and I have no plans to push this hard. Just wanted to make sure I was not doing it wrong. I...
