Hello all, I've had an SE/30 that I've shuffled in and out of working on over the past year or so, along with my many other dead Macs. I managed to fix a video problem it had after recapping it, and it would boot, but only if nothing was on ADB. Thus, I tried swapping the ADB controller chip with a known working one from a Mac classic. Same markings, same footprint, so surely it should work, I thought. Nope! It caused the previously booting SE/30 to enter a state of permanent simasimac, even after restoring the original ADB chip. Have I fried something, or could it just be coincidence? I wouldn't think that it would completely break without the ADB controller, but with how fickle these machines are I wouldn't be surprised. There is no chime, no response to anything on the board other than the reset button. This thread is my last ditch effort before I bite the bullet and buy a new board for it, but I'm still holding out hope that maybe it's something obvious that I'm missing. Any help is greatly appreciated! | Posted by: djc6 on 2024-12-15 07:43:10
is the orientation of the new ADB chip correct? Any solder bridges between pins? There is some ADB troubleshooting in this thread: https://68kmla.org/bb/index.php?threads/se-30-with-dead-adb-ports.8279/ | Posted by: DannyDorito on 2024-12-15 10:52:42
No bridges, all pins seem to be connected and I'm sure it's oriented correctly, I took a picture before doing this, and it matches. Markings on the chip are properly oriented if looking at the board with the ports facing away from you. And still, would a dead chip prevent any activity elsewhere? | | 1 |
