Questions
How big is the Turbo r-1mb PCB?
It measures 70.3 × 27 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Turbo r-1mb use?
23 parts, built around the CD74HCT367E, CD74HCT30M and SN74LS670D. 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 Turbo r-1mb KiCad files?
From the timembedded/msx-hardware repository on GitHub, at the commit this page was made from: the board is fs-a1gt/turbo-r-1mb/turbo-r-1mb.kicad_pcb and its schematic fs-a1gt/turbo-r-1mb/turbo-r-1mb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Turbo r-1mb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
