Hey I still have a couple programs I put on papertape via a Teletype mode 37 console in my very early days programming. It had a papertape punch/reader that used a Western Electric 5 bit code (often mistakenly called Baudot code) The same type paper tape was used in some communications computers I saw later in the Air Force on AN/UYK-7 systems.

Growing up we had a neighbor who had a player piano and they had several rolls of music which used holes in heavy paper to play the music. The wife worked for a well known '3 letter agency' and had arranged to have a few rolls that they played fairly often transferred to a mylar material roll. She said they used rolls of the same dimension to store keys for crypto systems and she kept a couple rolls at the office that they would use to test the punch machine after maintenance without having to use rolls that had to be secure. She said one of their guys rigged up a speaker so the computer could actually play the music as part of the test. This was back in the late 60s

Reality can be stranger than fiction!

I so want to do the opening notes from "Close Encounters..."

There is an updated version of the old piano rolls that was used to record Gershwin and others. You can actually listen to them:

If he donated that to a charity, would that make him an organ donor?

But player pianos ain't computers.

If they were, then record players, film projectors, televisions, cassette players, DVD players, etc. would all be considered computers as well.
