Thanks Yvan. I was hopeful when the terminal output the standard status
line at the bottom with an 08 code in the lower right above the line and
a blue K in the bottom center below the line - which I assumed was a
keyboard not present error. I could not find the address switch
anywhere on that terminal to configure it. The previous owner said it
was the system console so I assumed it was already set for address 0
'somehow'.
I also assumed the hard drives were bad or the load on them was corrupt
when never saw any terminal output after nearly 30 minutes. First thing
I should see is the numerical countdown after 4-5 minutes, correct?
I have only disk 1 of SSP 3.0. When I try to start the machine using
function 3/1000, it throws SRC 210F which the code-manual describes as
not being able to find valid sector marks. Not sure if it's a problem
with the media or the drive at this point.
The machine came from a young man who didn't know much about it. He
said it was his fathers and it worked last time it was in-use. But that
was at least 15 years ago. It has been siting indoors for that time.
So there is hope. The bearings in the hard drives sound pretty bad.
But during what I assume is the normal IPL (with no terminal output),
the drives are spun-down and then back up again in sequence about 1-2
minutes in. I can also hear the heads engage and vigorously move about
a minute past that for a while - which I assume is the IPL trying to
load the CPU kernels - but I obviously never get to the IPL sign-on.

You will need the keyboard. Those terminals usually
don't come up without it. Good news tho if the keyboard has been nicked, the protocol
is compatible-ish with PS/2. I have successfully used $generic_ps2_keyboard with the right
plug for it. Make sure to not hit the Windows key (or any other 'new' keys) -
you'll lock up the terminal's firmware.
You will also have to configure the terminal to use address 0 - Twinax busses have an
address range of 0-7 and you need bus 0, address 0 for the console.
Generally speaking, bringing up the system is similar to bringing up early AS/400s.
