At least you can think of the cards as spares.  That always makes me feel
better in that situation...

Others have pointed out the machines that had transcended the 512MB limit.
I had wondered about which machines these messages in VMS SYSBOOT.EXE were
relevant:

-W-CPUREV, CPU rev level prevents use of memory above 512Mb
-W-XMIREV, XMI adapter rev level prevents use of memory above 512Mb
-W-OLDBIDEV, old BI device prevents use of memory above 512Mb
-F-Pageable system space exceeds 512 MB

I never had a problem. I think you had also mentioned changing the serial
number the boards reported so they matched your original system.  I wonder
if that feature might just be intended for VMS licenses keyed for a
specific hardware ID and not a functional necessity otherwise.
