liveboxandy/ZX-Spider-48ZX Spider 48K by 'Skoti' https://github.com/konkotgit/ZX-48-Spider recreated in Kicad 10 to get a full ibom including tracks and vias. The gerbers in the Gerbers folder are those from Skoti. I would NOT generate gerbers from this pcb and have boards made without fully checking every track and via for position.

This is yet another retro computer running CPM on an actual Z80 CPU with a twist. Instead of using a traditional UART for communications, it uses a RPi pico module that is no bigger and no more expensive than a UART.

Questions
How big is the ZX Spider-48 PCB?
It measures 213.5 × 130.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ZX Spider-48 use?
150 parts, built around the 74HCT240D, 27C256-17/J, 74HC04D and 74LS00SC. 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 ZX Spider-48 KiCad files?
From the liveboxandy/ZX-Spider-48 repository on GitHub, at the commit this page was made from: the board is ZXSpider48.kicad_pcb and its schematic AY2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZX Spider-48 design in my own project?
Its repository states no licence, so its author keeps all rights: ask liveboxandy before reusing the design.
