=== Generic Array Logic (GAL) ===
GALs, were introduced in the mid-1980s, came towards coinciding with the end of the 8-bit computer era , but they still found applications use in later designs and modifications. One of their main advantages was being electrically erasable and reprogrammable, which distinguished them from traditional PALs. This feature allowed developers to easily make adjustments without needing new chips.
Key differences from PALs:* Electrically erasable, allowing for reprogramming* Often GALs were also often pin-compatible with PALs, making it easy to swap them popular in for prototyping and upgrades. This compatibility led to their popularity in various applications, especially where quick changes were needed.
Applications:* In practice, GALs were often frequently used in for aftermarket upgrades or and modifications to existing 8-bit computer designscomputers.* They allowed hobbyists and small companies to create custom expansions more easily, promoting innovation in computing. Overall, GALs played an important role in linking classic 8-bit systems with newer technology demands.
