Actually, I was back over at my museum earlier this evening, to put the cleaned and repaired front panel on the 8/e... I took the time to power it up myself, and did a little playing with loadadrs and dep... I verified that I can address both fields (0 and 1)... it has 8k. I checked the EMA lights, and they all light. I tested the address lights and they all light... I checked out the data lights, they all light, at least in MD position... I've yet to check the other positions...
