It supports a variety of instruction sets, including Basic and FORTRAN IV, making it versatile for various data processing applications.

The system's input and output methods primarily relied on punch cards and paper tapes, with a capacity of 80 columns and 80 rows for punch cards and 1,500 characters per inch for paper tapes. These input and output methods were commonly used during the era of the system's production due to their affordability, reliability, and ease of use. The TEAC EAS-20PW09 also features a built-in cassette tape drive for backup purposes, which could store up to 14,000 80-column records.

The printer for the TEAC EAS-20PW09 is an impact matric printer capable of printing up to 80 columns and 12 lines at 8 characters per inch. It was designed for ease-of-use, with a mandatory paper load function that simplified paper handling and guaranteed optimal print quality. The operator interface features a set of alphanumeric keys and control keys, allowing users to interact with the system via an intuitive and programmable console.
