On trouvera ci-joint le catalogue de ces machines en There were four generations of card punch equipment preceding by Bull. That product line is based on the 80 columns punched card.
However, most models were also available with the 45 columns round holes option. Since the Calculatriec patents were invalidated in France inthe product line was limited to 80 columns cards. The Optional machines were: However, if the program connections panel is specific of each machine tabulator, sorter, calculator Data on punched cards are fixed length unit records.
Fields may be numeric, and may be subject to arithmetic operations or alphanumeric essentially for printing. Data are represented on 12 positions rows.
Often a field is used as a record key, allowing specific processing of a group of cards. Equipments use essentially electro-mechanical technology as were the first generations born before Second World War.
Electricity is used in powering the motors and the electro-magnets that command the clutches, the printer or the punch hammers. The reading of the cards is made by metallic brushes that made electric contacts through the holes in the card -the card paper being an insulator.
The big relays were similar to those used in the s for telecommunications calfulatrice.
The main part of the logic is mechanical and required appropriate adjustments. The use of relay-based logic was relatively limited.

Compagnie des Machines Bull was developed from the s in France to exploit Frederick Rosing Bull’s patents, by card board paper manufacturers, the Callies family. The reading of the cards is made by metallic brushes that made electric contacts through the holes in the card -the card paper being an insulator- The big relays were similar to those used in the s for telecommunications equipments.
Punched card equipments were the workhorse of the Compagnie des Machines Bull from its creation.
