Everytime the computer thinks the NVRAM is okay, my keyboard refuses to work and when it is complaining or I just pull the RTC out of the socket it works. What is this? I am so frustrated ...
... I just don't see the connection, but soldering a new battery in is the last thing I can do ... but how can that fix the keyboard problem?
I wonder if there's an issue with the RS423 port. I'm not overly familiar with DEC computers, but the fact that those two types of keyboards require a fixed baud rate of 4800 leads me to believe that perhaps the garbage data the keyboard produces sometimes is an incorrect baud rate setting sneaking in somehow. Perhaps when you pull the RTC the baud rate issue is corrected temporarily.
Again, I have no experience directly with DECs, but if I had to guess where to look at this point, that would be next place. Hope that helps somewhat.
I bought the most recent RTC I could find on eBay, from 2011, because I do not have the right tools for a repair. So, the Keyboard works since two bootups. It looks like you can not chance change any baud rate in the SRM console, but the problem seems solved and I can boot OpenVMS in a graphical enviroment.
