Hey Ike,
just a few random thoughts I had when looking at Uniserver's problem:
I guess you checked everything around the SWIM that has to do with writes: write (WR), write request (WRREQ), FPH3 (write strobe). I'd also just make sure that there are no shorts between any pins on the swim.
But I think you've done most of that already, so I reckon the write signal doesn't make it to the floppy drive. Did you check everything around UH7 (especially pin 4 and 16 to swim /floppy connector). Also check the pins on UH7 that go to the GLUE chip (page 3 of the SE/30 schematics that can be found on net) because that's responsible for inverting that WR line...if any of those are faulty could be a prob.
Finally did you check around L22 inductor/C67 cap and R30 resistor (around SWIM and floppy connector) as they are all part of the WR line...long shot though!
Hope you'll get it working
