About 20 years ago, flipping channels, I caught the end of some classic BBC sitcom of the 70s. Maybe The Two Ronnies? A long time ago but also a long time after its original showing. One of the Ronnies (the little one, if indeed it was the Ronnies*) was in an office when a mystery parcel arrived, which turned out to be a calculator similar to what Wow describes, accountants for the use of.
*Makes them almost sound like a Motown girl group.
