Hey everyone! For some reason I decided to build a CPU from scratch starting about five years ago. My BOM is NPN BJT transistors, 100/1k/10k ohm resistors, 47uF ceramic capacitors, and LEDs used as visual indicators/in-circuit debugging aids. The technology is basically RTL and compatible with TTL voltage levels. The components are designed and laid out by me using KiCad. The boards are manufactured by OSHPark. The ISA is my own design. I'm partially through board design and layout.

Documentation, schematics, stdlib/BIOS source code, simulator, assembler/disassembler, and other utilities are all available here: https://github.com/dragonMinded/minidragon

For those who have followed me awhile, especially when I was on my previous instance, this is not news. It might even be why you followed me. But, I wanted something to pin to my profile. Also, I wanted somewhere to post that I am going to be using the #MiniDragon hashtag in CPU-related posts from now on if that's all you're interested in seeing.
