Questions
How big is the Vhd if c9d PCB?
It measures 145 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vhd if c9d use?
74 parts, built around the SN751701P, 27C256-17/J, 74LS30PC and 74LS02PC. 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 Vhd if c9d KiCad files?
From the popolonx/MSX_STUFF repository on GitHub, at the commit this page was made from: the board is vhd_c9d_card/vhd_if_c9d.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vhd if c9d design in my own project?
Its repository states no licence, so its author keeps all rights: ask popolonx before reusing the design.
