README
README.md#What is this?
This is the source repository for esppdp, which is a tiny VT-102 scale model housing an ESP32 emulating a PDP11. You can connect a BlueTooth keyboard to it and play the original Tetris, or do some die-hard computing on 2.11BSD.
#Why?
Well, someone had to put back the 'mini' in 'minicomputer', right?

Questions
How big is the Esppdp PCB?
It measures 43 × 49 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esppdp use?
55 parts, built around the CH340C, TP4056, S8050 and AO3400A. 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 Esppdp KiCad files?
From the Spritetm/esppdp repository on GitHub, at the commit this page was made from: the board is pcb/esppdp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esppdp design in my own project?
Its repository states no licence, so its author keeps all rights: ask Spritetm before reusing the design.
