I want to trace out the bus grant signals on my /45 to make sure there's not a break somewhere. However, I don't see the backplane printsets on bitsavers. I could start at the first unibus slot in the system backplane and check BG4 through BG7. However, I'd rather start at wherever those 4 signals actually originate. It's pretty hard to identify visually what pins and where, so I wanted to check the prints. Then I can check from where BG4-7 orignate to the end of the bus and make sure I have continuity. Can some one point me in the right direction? Jay West
