Congrats on getting the board to boot up, even with some unresolved issues. I’ve tackled two battery bombed SE/30s with the first resulting in a 98% working board with just some issues around the serial ports which causes a lock up when testing with snooper. The second board was much more badly damaged and after installing 40-50 bodge wires with probably the same again ahead of me, I called time on it and instead ordered up some “Bolle” reverse engineered PCBs and transferred the components over. I actually got some help from you regarding snooper and the loopback plug required at the time on one of the forums. This new PCB effectively worked first time, ignoring some preliminary checks with chips removed, and has resulted in a machine that could easily still be working in another 35 years. On one hand I was proud of my soldering but at the same time I was amazed that it all came together so relatively easily. To be honest, this gives me mixed feelings because it’s a bit like taking a racing car that competed in Monaco with Sir Stirling Moss at the wheel, and replacing the chassis because it was a bit damaged. It loses some authenticity right? But at the same time, the end result is so much more likely to last the distance. Not trying to put you off continuing with the repair but if it gets to a point where you just can’t make forward progress then please consider doing a second series where you replace the logic board with a modern replica and migrate the chips across. I think that would be a very interesting “season 2” of you project if it came to that. Keep up the good work, and thanks for playing your part in inspiring me to refurbish my SE/30s.

I have a SE-30 to restore this coming up winter I am glad it did not have any battery damage just need to replace those dreaded electrolytic capacitors and rebuild the analog board .

Great that you got it working! For the problematic via, how did you know there was “something in the middle”?
@BranchusCreations
@BranchusCreations Рік тому
By using the schematic and the multimeter. The signal was supposed to go to three locations on the board, but it was only going to two.

Moral of the story: always put a blob of solder in every via that you run a wire through.

Oh crap, these all in one Macs have internal layers in the PCB? My battery damaged Classic might be screwed then...
@BranchusCreations
@BranchusCreations Рік тому
You'll be pleased to hear that there are no internal data layers in the classic logic board, only power and ground. The Classic is a 4 layer board (the SE/30 is 6 layers).

@@BranchusCreations oh thank goodness! The battery nuked what I assume is either the address or data bus, so it's not power or ground 🤣 I'm still not super confident it will work when I'm done, but it's been fun working on it.

@@rpavlik1 Have you seen the Classic reloaded project? You can transfer all the components to to a brand new PCB if needed.

@rpavlik1 Рік тому
@@BranchusCreations yes I have. If this doesn't work that will be my next step. Right now I'm just trying to figure out how specific I need to be in my analog board capacitor replacements, trying to match series and things like max ripple and impedance. Had two definitely dead caps and of course I have nothing even close in capacitance and voltage rating, and so if I have to order I may as well order most or all of them...
