On power-up, the Console shows all 0000000 and the
'Run' led...
data can be entered into the disply but apparently not deposited...
There is no SLU response on power-up, and I have an RS232 sniffer in
the line and it indicates the proper static levels, but no data.
Sure looks like a bus grant problem. I think there's an NPR/NPG jumper
problem, a loose bus grant chip (plug), or a not too well seated
terminator some where.
