Here is the answer folks… The croaked HDD that was still in the machine and connected was creating chaos on the data bus or so it appears. I disconnected it and SSD boot drive and the thing booted in 10 seconds. On my way to prepping new larger HDD to install in the machine. With Apple being Apple I'm expecting some boondoggle once I connect new spinning drive for it's first boot. Check back in a couple of hours if interested.
