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 68008test PCB?
It measures 80 × 67.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 68008test use?
17 parts, built around the TC1232CPA. 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 68008test KiCad files?
From the epaell/MECB repository on GitHub, at the commit this page was made from: the board is 68008Tester/68008test.kicad_pcb and its schematic 68008Tester/68008test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 68008test design in my own project?
Its repository states no licence, so its author keeps all rights: ask epaell before reusing the design.
