Questions
How big is the Vga PCB?
It measures 127 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vga use?
39 parts, built around the 74HC273D, 74HCT574D, 74LS04PC and 74LS32SC. 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 Vga KiCad files?
From the rustbox/cuddly-robot repository on GitHub, at the commit this page was made from: the board is eeprom-sync/vga/vga/vga.kicad_pcb and its schematic eeprom-sync/eeprom-sync.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vga design in my own project?
Its repository states no licence, so its author keeps all rights: ask rustbox before reusing the design.

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.
