Lamont updates CoCo Docs and some Math

Chris Lomont has made several updates to his CoCo page since we last visited back in June (I really need to get out and about more). There's an article called "Retro Supercomputing" in which he tackles some heavy duty computational tasks with a CoCo 3. Okay, mathematics are not my strongest area, whereas Chris is a PhD, but just seeing the programs run on a CoCo is pretty darn amazing once you understand what they're doing inside. Chris's description of the inner workings of both the E and TM computations is clear and easy to follow in the article and in the programs themselves. The way he gets around some of the inherent programing limitations of the CoCo is pretty slick as well (such as overwriting an unused portion of the program itself to free up more RAM) and certainly worth studying if you're planning to do some memory intensive CoCo'ing. Can't wait to see what he does with Pi.

In other news, he recently updated his CoCo hardware programing documentation. It's easier to navigate around and there are many new additions from the last version. If, like me, you're learning assembler again, grab these docs right now. Just being able to see how all this stuff works and interrelates is a huge kick to the ol' learning curve. Between Mr. Lomont's docs and the Barden and Leventhal books, I'm actually starting to get it. Well, mostly, but way better than I was previously. If you're already a whiz with a CoCo assembler, Chris's docs will serve as a welcome and frequently used reference.

Angel's Luck,
