Thank youYes. I've attached the SE/30 schematic. The first page has the PDS slot. Pins 4, 44, and 84 are the 3 Interrupt ReQuests (IRQs). Slot pin 84 (IRQ1) should have continuity to pin 2 of the chip at UK11 (page 4 of the PDF). Pin 44 (IRQ2) should have continuity to pin 3 of UK11, and pin 4 on the slot should have continuity to pin 4 of UK11.
