@tERBO Something worked!   

I flashed that image you shared.  It was not promising; as the VFD display was not working.   
 
I redownloaded Multitool and a different Armbian image from @jock's stable folder and flashed a different microSD using a different computer.  

Happy to report that I have a live system now!  I wish I had asked sooner before wasting nearly a day going in circles!   Thanks for the assistance - was nearly ready to send this board to eWaste recycling.
