SE/30 with DayStar Turbo 040 Struggles

[jasonfortheworld]

So I decided to just see what happens with the SE/30 board that can't boot properly. I get stuck at the question mark floppy screen, but I can move the mouse normally.

I added the Bolle adapter, the Turbo040, 4x1mb of RAM, and the stock SE/30 ROM to the damaged board and booted.

To my surprise, I was able to get to the question mark screen and move the mouse around. Now, this may not be definitive proof as I have no idea what's wrong with the broken board, but I'd say that strongly suggests the Logic Board of my original SE/30 may have underlying issues I haven't discovered that are messing with the use of the Turbo040.

Now I just need to figure out my next step to troubleshoot the original SE/30 logic board.

So while progress hasn't been made, I was able to confirm that my logic board has some kind of underlying issue with it.

With the wonderful help of @AEChadwick I was able to use my Bolle riser and Turbo 040 on his SE/30 without any issue at all.

But that means I'm officially out of my comfort zone. I have zero skill with hunting down logic issues like this, so I'll need to find someone who's able and willing to take a look at this board.
