And along the way, write some interesting code.</p> <p>We are coming up on the 50th anniversary of the first release of UCSD Pascal, and I thought it would be fun to poke around inside of it, and develop some tools (in Rust) to bring this "portable operating system" to modern hardware.</p> <p>The series of blog posts is ongoing, but it starts here:<br> <a href="https://markbessey.blog/2025/04/14/a-blast-from-the-past/" rel="noopener noreferrer">A Blast From The Past</a></p> <p>I'd love to hear if you have any memories of the p-System, Apple Pascal, or any of the other topics I touch on in the posts.</p> programming rust computerscience
