My Ruby ‘816 pages:
- Build and initial Booting
- Hardware description
- Software (part 1)
- More software and the Bootstrap Paradox
- The importance of testing
- Premature optimisation and all that
- Solving the bootstrap paradox
For me, the 6502 processor is something of an icon. It was one of the first processors I used to write programs on and the first one I experienced assembly language programming with.
So for my 40th anniversary of using the 6502, I built my own 65C02 SBC and enjoyed using it. That’s all (mostly all!) documented here.
After the 6502 was the 65816. At the time, I never used one myself – the only real accessible system back then was the Apple IIgs and a good friend had one and it did seems good and fast (for the time), so after my Ruby 6502 board, I decided to make a Ruby 65816 board.
These pages are my logs and documents about that process and the software I’m using on it.
