The P80 manual card puch was used to create small decks of cards or to correct cards in cases of emergency. It was purely mechanical and operated without any need for electric power. The keyboard was numeric only, but the operator was able to punch several holes in a single column.
The Por Keypunch was derived from the P80, but was electrically powered.
The Porod was the same as Por but with an added alphanumeric keyboard
This machine was a block puncher (or gang punch) used mainly for reproducing card decks at a speed of up to 160 cpm. It had the option of punching cards from a numeric or an alphanumeric keyboard.
The Peler was a electrically powered serial keypunch, but with an automated feed and ejection mechanism within a ergonomic enclosure. It allowed reproduction of constant fields. The Peler had a numeric Keyboard.
The Pelerod was identical to the Peler with an added alphanumeric keyboard
It was the workhorse of keypunch shops until the 1970s
The Pelerod CV model means that cards are under the
operator visibility.(CV means "carte visible")
A master card is used to insert constant and control the field tabulations.
Peler and Pelerod were replaced in the early 1960s by a new model P112. While series 150 were decommissioned at the end of the 1960s, manual keypuncher were still used with Bull, GE and Honeywell computers during the 1970s.
In that machine, the control card was rotating on a mechanical drum. A numeric keypad was added to the alphanumeric keyboard.
P112 was used in Bull encoding format and was also available for punching IBM encoded cards that became standard in the early 1970s.
