Bizarre SE/30 Problem

[CC_333]

Hi,

I am working on another SE/30 logic board, and have done a full recap. It works perfectly (good, loud bong and all), but I can't move the cursor. Now, what makes this odd is that it will still register clicks (the Apple menu will open when I click) and the keyboard works fine, but I can't move the cursor!

I've tried two mice, and they both behave the same way.

Why?

i'v had L1 go out before...

other wise its a trace issue.

i would check 

C13

Q3

UL11

we know F1 is good because the kbd works…  I'v had blown out F1 before as well.

OK, C13 is good I think, but Q3 is suspect (it took some relatively heavy corrosion).

I'll take a look at UL11 as well.
