Roadmap IBM i.png

Prior to the arrival of IBM i, System/38 was highly regarded for its object-based design, integrated relational database and security. IBM aimed to merge its entire mid-range and mainframe product range. This project did not entirely succeed, but did result in a number of innovative products, notably the 9370 and the AS/400.

The AS/400 was released in 1988 to enable users to run applications written for the System/38 and System/36. The AS/400 gained a reputation for high reliability, low cost of ownership and ease of administration.
