The main difference between an IBM 24 keypunch and an IBM 26 keypunch lies in their functionality and design. The IBM 24 keypunch is designed for creating punched cards with up to 24 columns, primarily for data entry tasks. In contrast, the IBM 26 keypunch can handle 26 columns, allowing for more data to be encoded on each card, which enhances its efficiency for larger datasets. Additionally, the 26 keypunch generally incorporates more advanced features to facilitate higher-speed data entry.

A keypunch machine is used to encode data or instructions by punching holes in cards that will be read later by a computer using a punch card reader.
The average alphanumeric keypunch speed is around 8,000 to 10,000 keystrokes per hour. However, individual speeds can vary based on experience, skill level, and typing technique.
The keypunch operator entered all the data into the new system.
The 610 was called the "Autopoint Computer", it was basically a modified keypunch connected to an electronics chassis.

Because the computer can't read my thoughts and I need some way to tell it what I want it to do. When I first started using computers you used punched cards to do that and the keypunch that punched the cards had a keyboard but was not connected to the computer. You punched the deck using the keyboard on the keypunch, then took the deck to the computer's card reader.
