Remington Rand 90-koloms ponskaartsysteem
De informatie op deze en een vervolgpagina is verkregen van dhr. Oliver J. Jones, Garden City, NY, USA met als doel computerhistorie vast te leggen en te bewaren. Remington Rand, een concurrent van IBM, gebruikte 90 kolomsponskaarten bestaande uit twee rijen van 45 kolommen boven elkaar om het IBM patent te omzeilen. De ponsingen waren om dezelfde reden rond (IBM rechthoekig). Daardoor waren beide systemen incompatibel.
De gebruikte codering was overigens efficiënter dan IBM’s Hollerith code.

“I joined Remington Rand in 1947 and with the exception of the electronic sorter most of the equipment was already documented and running. I am amazed how little is known of Remingtons contribution to the computing field. Most of us were hired after WW II and at that time Remington Tabulating division had been in operation since the 1930’s. They had an exhibit at the 1939 Worlds Fair. We trained in Ilion New York a village in the Mohawk Valley and when a new piece of equipment came out, back we went to Ilion for more training.
I will try to give here the a background of Remington Rand and its contribution to the punch card tabulating business. The photos below are all from a book given to all new employees joining the service department at that time. We were a group of young men most of us recently veterans of WW II. The training was a six month course in Ilion, New York a small village in upstate New York Remington Rand concentrated. All its manufacturing was in this area and the school was located in the factory. Whenever a new machine was brought out you went back to Ilion for update training. We lived in furnished rooms and the winters in that area were severe salaries were very modest but the training was excellent. Upon graduation you were assigned to a regional office in the United States. I was assigned to New York.In that area we had many important customers like Macys Dept Store, The Tax Board of NYC, Brooklyn Union Gas, US Navy Medical Dept etc.
The machines were mechanical marvels and all parts were made in Ilion by engineers and machinists from the local area. Today it would be hard to find people with the skills of these men today its all electronic.
Some of the machines had over 40,000 small parts and tolerances were limited to .0005 + or -. You will not find today machinists with the skills to turn out the complex parts that were needed to make such mechanical marvels.
IBM became a real competitor in the late 1950s and featured a 80 column card with square holes and electronic tabulator. You may ask what happened that made IBM the leader in the field. I have a theory: Remington waited to long to convert to electronic small equipment. James Rand was a self made man and a tough boss which led to many labor disputes. IBM had a more aggressive sales force and publicity team. Unfortunately we waited to long to join the electronic wave. We purchased Univac to try to catch up and used some electronic systems from France ( BULL SYSTEMS ) but it was to late. The 80 column card became the norm and IBM won the business market. Today only Univac large systems survive.
Those mechanical systems I am sad to say all wound up as scrap. I doubt if one example survives today.
I left Remington Rand after twenty years in 1967. I joined a medical instrument company eventually becoming service manager of the seven north-eastern states and the Caribbean. I credit my success to the training and perseverance learned in those early days. What a shame not one of those early systems exist today. I retired in 1988 after 40 years in the customer service field.”

Below we show pages from a book on tabulating machines, the machines that processed punchcards as source of information. Moreover, a scans of a 90-column punch card i provided. Detailed technical graphs show part numbers of a Collating Reproducing Punch and an Electronic Sorter (Remington Rand types 420) here.
But first the punchcard:
