The company where I was an apprentice around 1970 also had two electronic computers in addition to plug-in programmed punch card machines: a Bull Gamma 30 (rca 301 , gamma 30, Bull, chr4inf9,) and a Siemens 4004. The Bull calculator was bought, I believe, for political reasons, because the owners were French. The downside for us was that we had to learn two punch card codes: the Bull Code and the Hollerith Code (which I personally found more elegant). Here is a comparative figure from the manual we got at the time.

Don’t miss the Bull Gamma 3, the machine that challenged IBM punchcard appliences to a degree that they eventually countered by the IBM 1401.

Oh, mistake. It was the Bull Code which I personally found more elegant.
