SDCardShield/README.mdSDCardShield
A version of the SD Card shield that was originally developed by Corsham Technologies for the SWTPC. It has been modified to work with the MECB I/O board (PIA port) and makes use of Adafruit modules to implement the realtime clock:

Questions
How big is the SDCardShield PCB?
It measures 139.8 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SDCardShield use?
26 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 SDCardShield KiCad files?
From the epaell/MECB repository on GitHub, at the commit this page was made from: the board is SDCardShield/SDCardShield.kicad_pcb and its schematic 68008Tester/68008test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SDCardShield design in my own project?
Its repository states no licence, so its author keeps all rights: ask epaell before reusing the design.
