Based on the docs I got from Ashley I was able to re-arrange the memory 
section to be sane, cards were in the wrong slots. I was also able to get 
the jumpers set right on the G110 card. Now when I power up I can definitely 
read core correctly. There's a random assortment of data in sequential 
locations and returning to those same locations I always get the same value. 
That's a plus.

However, I can't store anything. Anytime I store a new value in a location, 
that location gets all zeros. Moving to another location I get data, and 
moving back - zeros. So it appears to be challenged in writing, but not 
reading, memory. The plot thickens :)

One thing I can't be sure of that the docs from Ashley don't say for sure is 
how to configure a less than full section of memory. I ASSumed you start 
from right to left, but in the HP core section that would be a bad 
assumption. Humm... But if I had that wrong, I'm suprised I'd be able to 
consistently read memory locations. A different G231 and G110 and H214 
didn't change the problem.
