README
README.mdLoop Microcomputer
a minmal 8-bit machine that is...
-
... independent:
- contains all the tools required to design another version of itself
- does not require high soldering skills, uses through-hole parts only
- uses only "evergreen" parts that have been in production for decades and are still made today
-
... aproachable:
- simple through reduction
- NO hidden complexity behind brittle abstractions
- open source and self-documenting
-
... powerful, with it you can:
- learn/teach how computers work
- design electronics
- control CNC machines / 3d printers
- play games

Questions
How big is the Backplane PCB?
It measures 218.4 × 132.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Backplane use?
109 parts. 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 Backplane KiCad files?
From the Noah1989/loopmicro repository on GitHub, at the commit this page was made from: the board is hardware/ecb-prototype/backplane/backplane.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backplane 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).
