Q700 ADB or board kaput? Mouse clicks but no movement

Thanks for the links, @trag and @CC_333. There's not a whole lot of Iici-specific content in the last link to the Pina Mac II book and even less for troubleshooting ADB, but it seems like I'll want to check out the 4-pin EMI RFI board filters that I think are the black cubes with what I describe as having 4 staples (L3 is the filter parked behind the ADB ports)

I'm attaching some photos in case someone with better eyes sees anything obvious. The polyfuses (F3 in particular) look good/closed and I'm just not sure what else could have gone bad.
