Very little of the stuff I've bought new has had such seals (with some
things, like my audio equipment, you are _expected_ to remove the
covers, the user manuals tell you how. They also include the full
schematics). Ditto test gear (if there is a seal it voids the
calibration only), computer stuff, etc.

I don't think DEC ever put such seals on their machines when new.
Certainly not on things like power supplies,]
