I have not yet, but have thought of it. Where would it be best to check them all from? I was thinking the PDS slot possibly?

I get the same issue with a floppy boot of OS 7 unfortunately. So something signal must be missing.

That is my beautiful badge wire for a broken pad.

There was not a whole lot of corrosion. The bodge seen was from me ripping a pad. Swapping from bank 0 and 1 or vice versa results in the same issues.

I've got a recapped Macintosh SE/30 board that I have been fighting with here and there over the years. It will boot into System 6 but will either freeze or system bomb on the ram test. Trying system 7 it will either bomb on boot or freeze on boot. I have tried many combos are verified ram Simms...

Well the issue is System 7 will not boot at all. It was suggested to me by someone else that System 7 needs a working RTC circuit unlike system 6, not sure if that is true. But I am still stumped on why it will not boot into any version of System 7 I’ve tried, it either hangs onto Welcome to...

Did both VIAs and the RTC chip, no change.

I haven’t really touched it since, so haven’t tried replacing those yet.

Just various ram stick it’s matched pairs installed, but no matter what combination they are in or if any, same results. I should be getting at least jail bars with nothing installed but I don’t.

Hello, I’ve got this SE/30 that I’ve been trying to troubleshoot for quite some time now. It’s been recapped, the analog board works with a working SE/30 board. I’ve tried and swapping all the swappable chips from my good SE/30 board to my bad one, no difference. Replaced UE8, UF8 and the...

Thanks for the suggestions. I spent a few more hours and found two more bad traces from the ROM to the CPU, and I assume the damage is under the ram slots. I tried fixing those two but it made things worse somehow. At this point I have spent too much time on it and will just part the machine...

I’ve got a Macintosh iisi that turns on and chimes. It will output either a grey, yellow or purple screen for a second then the monitor will turn off. With no ROM it will stay on a solid color indefinitely. It also does seem to boot off a floppy disk and the cpu does get warm. It seems like a...

It does chime and it does boot into the OS as I can hear Mac OS make some noises

Recapped the display on a powerbook 145, replaced one of the caps on the inverter and replaced the display cable with a new one. But I only get the backlight, nothing is displayed on the screen. I checked for continuity between each pad and trace for the caps and all were good. Any ideas what i...

Just read it now. I’m not familiar with the VIA chip but I’ll look for it when I get around to it tonight. What part of the board is it at?
