Hello Don,
I think there may be a misunderstanding on your part. The CDs that you receive as part of Developer Suite do not actually contain "updates" to a previously installed version of LabVIEW; they are stand-alone installers. Every quarterly shipment of the Developer Suite CDs contains the full version of LabVIEW, along with the included toolkits and other National Instruments software.
In other words, if you have any set of Developer Suite CDs, you can start a new install of LabVIEW et al. immediately. You don't need any so-called "original" CDs.
Good luck!
Mike N.
