README
README.mdpicoMBC
picoMBC is a generic Pi Pico expansion card for the Sanyo MBC-1000 computer. The primary goal is to add an SD card interface for mass storage, but with some available I/O for future or alternate use.
The MBC-1000 expansion interface is a buffered breakout of the Z80 I/O interface. It does not provide the upper 8 bits of the Z80 address bus or signals required for memory space addressing or DMA. To save I/O, picoMBC multiplexes the 8-bit data and address busses.

Questions
How big is the PicoMBC PCB?
It measures 100 × 145 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoMBC use?
43 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 PicoMBC KiCad files?
From the techav-homebrew/picoMBC repository on GitHub, at the commit this page was made from: the board is hardware/picoMBC.kicad_pcb and its schematic hardware/picoMBC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoMBC design in my own project?
Its repository states no licence, so its author keeps all rights: ask techav-homebrew before reusing the design.
