Voodoo mode is the ultimate test. Imagine having access to 4GB of memory from real mode.

Shameless plug for my https://blogsystem5.substack.com/p/beyond-the-1-mb-barrier-i... article from a couple of years ago. You'll find a deep dive on unreal mode (I just learned it's also known as "vodoo mode") and some hands-on code to play with it ;-P

Interesting article. I learned some things.

How hard would it be for Mr Github to add rss/atom feeds, I wonder?

wasn't this basically the consensus among numerical analysts like 20 years ago? i remeber reading similar arguments in goldberg's paper and various game dev forums circa 2005, so genuinely curious what keeps making this idea feel "new" to each generation of programmers who rediscovers it

I think you’re missing the point. This person is implementing various CPU cores on FPGA. The insights they can share from that complex process are sometimes interesting, because they are looking at the system from a new angle.
