OK - done. I attach a link showing the Channel1/channel2 readings for the address lines/UB3-UC3 testing.
Couple of points to note:
1. The legs on UB2 and UC3 were hard to get readings from - I had to scrape a bit. I guess the only way to confirm all is really OK is to take readings from underneath the motherboard and I didn't do that. They all got a reading eventually.
2. Nearly all readings looked like you said they would - the same shape waves, but the 6502 waves were consistently longer than the UB3/UC3 waves (see document)
3. The only one that looked in any way inconsistent to me was 6502 pin 19, UB3 pin 16 - again, see the document for the graph.
Beer.
