Questions
How big is the A520 ACCEL RAM IDE PCB?
It measures 82.6 × 83.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the A520 ACCEL RAM IDE use?
46 parts, built around the MC68020RC20E and LM1117-3.3. 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 A520 ACCEL RAM IDE KiCad files?
From the PR77/A520_ACCEL_RAM_IDE repository on GitHub, at the commit this page was made from: the board is Hardware/A520_ACCEL_RAM_IDE.kicad_pcb and its schematic Hardware/A520_ACCEL_RAM_IDE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the A520 ACCEL RAM IDE design in my own project?
Its repository publishes it under the AGPL-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).
