Hi Todd and ??, thanks for your answers! I think it is a good suggestion to try to see first whether the Eproms are intact. Firmware is Version 3.11 and I have ordered new EProms to put a copy of the 3.11 firmware on them, the one from https://xdevs.com/fix/d1281/#manual . I will fire up my programmer the moment they arrive.
What makes me ponder is that there were suddenly apparently two errors after a couple of month's inactivity. If two errors appear out of the blue more or less at the same time, IMHO it is likely that there is a common reason. Hence first the Eprom test. Then perhaps the voltages, I still need to figure out what they are supposed to be at the test points of the undocumented digital board. (I am not sure whether the NVRAM error came exactly at the same first turn-on as the "9005.7 No Rtx 001B42" error, because it flashes only briefly and I might have overlooked it at first. I only noticed it after a few subsequent turn ons, when I tried to made a picture to the "9005.7 No Rtx 001B42" error display.) Assuming that nothing of the above works, which is likely, then there is still the main question of what the "secondary" part of the NVRAM is supposed to be. If it happens just a secondary backup copy of the whoke memory, then there might be a chance to correct it (like for Solartron 7081 which does keep 2 copies of the data). I keep you posted. Thanks for your help.
