Questions
How big is the Sorcerer DreamDisk PCB?
It measures 130.4 × 90.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sorcerer DreamDisk use?
63 parts, built around the 74LS245SC, 74LS367PC, 74LS00SC and 74LS123FP-E. 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 Sorcerer DreamDisk KiCad files?
From the RetroStack/Sorcerer_DreamDisk repository on GitHub, at the commit this page was made from: the board is KiCAD/Sorcerer_DreamDisk.kicad_pcb and its schematic KiCAD/AddressDecoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sorcerer DreamDisk 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).
