Adria is my second attempt to build a simple computer, based on a WDC65C816 CPU.


After I built my first homebrew computer, Lilith, I found out I needed a modular design. I had trouble expanding Lilith.

Available Signals

All 4 expansion slots have a seperate /IOSEL signal on pin 19. All other signals are the same for expansion slots.
I am trying to use the /DEVSEL signal, together with the /IOSELx signal, as an on-card ROM select. With this I will try to load additional ROM, mapped, from the card.



Kicad Template

I made a template for "expansion cards" for use with Kicad.
You can find an archive here (for now)
