## What Jamie wrote

What an incredibly geeky and delightful project this is. I fondly remember the [6502](https://en.wikipedia.org/wiki/MOS_Technology_6502) in the Apple II and Apple IIe. It was also in the Atari 2600 but I don't think I knew that back then. The Commodore 64 and the original Nintendo also had the 6502. So, you get the era we are talking about.

What I really dig about this project is that he is actually bringing in some new concepts for the OS. 

> I’ve written before about how I’m using vectors (on memory page 2) to provide hooks allowing user programs in RAM to invoke OS commands in the ROM. I now have about 42 of these. Because I’ve given over all of page 2 to these vectors, and each is two bytes, I have room for 128, which should be enough.

How fun. 🤓
