Located in Raleigh, NC I agree with UE8. The legs aren’t crumbling but they aren’t very pretty either 

Another update, I went ahead and removed that UD8. Most of the legs disintegrated when touched after all. Removing the chip shows damage to pads 1, 2, and 11. i don’t feel comfortable attempting a fix with my novice skills, so if anyone knows someone who can soldier on a new UD8 for me, I’d...

I've searched the chip number 74F253 and found three on Mouser that are surface mount...not too sure what the difference between these are. EDIT: Comparing the datasheets of the two top chips below (the two they have in stock), all pages of the datasheets are completely identical. The product...

After soaking in 70% isopropyl alcohol for only an hour (going to let it soak for at least a few more hours), it has really brought out how bad UD8 is. It really brought out the damage, so I want to say UD8 is my culprit. I’ll have to look into maybe finding someone to replace it. If anyone...

I did, but just to be sure, I just removed the ROM and RAM chips and I have it soaking in 70% isopropyl alcohol in a plastic container, we will see if that helps anything! Does anyone know of someone on here that would be willing to replace UD8 and maybe UE8?

The pins are definitely very corroded...one was broken on UD8 and I tried to reconnect it to the pad. Maybe that chip is just toast at this point. I don't think I have the soldering skills or proper tools to really replace that chip though, maybe i'll have to send my board to someone for full...

Do you know how I would check that and what voltages I should be getting?

Oh interesting! Good info! Maybe I do have some bad ram then, who knows!    no chime/sound, I should gave mentioned that! I’ll attach a photo of the screen (ignore the tiny happy Mac taped to it haha, it’s stored on my desk at work)

Hello all! First post on here. I found a free SE/30 in my area and have been trying to repair it. It had leaky caps so I recapped them (I’m not the best at soldering, but I can get by). The one cap (C4) took its pads and some trace with it, so I found the schematic and wired a replacement cap...
