Great news!
I managed to get the screen up and running.
I will try to be extra clear if someone else stumbles upon this as I did. To begin with the machine had a blank/black crt screen. The CNC Control came to life when hitting the ON buttonn on the operators control but no screen at all.
I also would like to give cred to Mr. Caprirs here on the forum who has written guidelines on how to carry out the procedure to re-initialize after battery went low and machine lost its concept.
In this thread there is a good write up. This one clearly states that you should start from top with the dip-switches and count 1,3 and 5.

What I did was exactly these steps:
0) Replaced battery (pre-requirement)
1) Main switch turned off.
2) On the MC1619 card flip switches 1,3 and 5 to the right.
(counting from top, I was confused by them being labeled 0-7 and unsure if guidelines referred to the actual count of labeling of dip switch)
3) Turned main switch on
4) Hit the green ON button on the control panel
5) Waited for 30sec
6) Hit the red OFF button on the control panel
7) Turned off main switch
8) Flipped switch 1,3 and 5 back to the left
9 Tuned on main switch
10) Hit green ON button
11) BLAAM Screen comes back to life
Unsure if the main switch has to be turned on/off. But I felt safer when standing with my nose in the electric cabin.
Next step would be to try load canned cycles and params. But that will have to wait for some days. Right now I'm just happy to get this far..
