minimOS
Please note that this doc is OBSOLETE. Read about updated details in the new architecture.md file.
Minimalistic, portable, scalable Operating System for everything from embedded devices to (quasi) full-featured desktop computers!
Purpose
Currently in a VERY early development stage, hopefully will become a common reference platform for deployment of computer-related appliances -- think about embedded systems, like the original intent: an Actual Exposure Time Meter for classic photographic cameras. But by virtue of its modularity and scalability would equally serve to a whole breed of home-made, retro-inspided computers.
Future ports
Initial target is the venerable 65(C)02 and its big brother, the 16-bit enabled 65816 (port known as minimos·16) which will keep compatibility with existing '02 code. But other ports to many CPU architectures are in mind, like the Motorola 68xx / Hitachi 63xx series (minimOS·63, with the interesting 6809/6309 branch as minimOS·69), 680x0 (minimOS·68), 8080/8085/Z80 (minimOS·80), even (God forbid! :-) the commonly used x86 (minimOS·86). I really have little-to-no knowledge about this CPU family, nor about the usual IBM-based PC architecture; hopefully someone will be able to port minimOS without too much of a chore, that would give a very interesting 'breath' to (otherwise useless) older PCs.

Questions
How big is the Durango PCB?
It measures 177.8 × 130.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Durango use?
159 parts, built around the 74HC245D, 74HC367D, 74HC157D and 74HC257D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Durango KiCad files?
From the zuiko21/minimOS repository on GitHub, at the commit this page was made from: the board is hard/kicad/durango/v2/v2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Durango design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
