And today we found out that people used to write operating systems in Pascal. One such example is the classic Mac OS (not the modern macOS): https://twitter.com/pikuma/status/1767613616214188179


And then there is ToroOS - an operating system written in Pascal.

Another discovery - pikuma.com has great classes and is a wonderful learning resource.
