Hi Mark,
As Eric Norum pointed out, I have a typo in my original note; I am using EPICS R3.14.11.
And yes,  The original software still works in the original VME setup.
I have both, the old and the new VME systems side by side.
But, the original software uses older version of the Allen Bradley support module, whereas my new IOC uses R2.2.
I attempted to build the version of AB software used in the original IOC against EPICS R3.14.11 and vxWorks 6.6 and I got lots errors, so I decided to try the R2.2 version, which built without errors.

Now I am thinking that perhaps I should look more closely at the difference and make modifications to the older version to fix whatever is generating errors and give it a try.
I could also try using mvme2700, since I have one sitting on my shelf.

Thanks Mark,
Zen
