From the project

PDP-8/V Vacuum Tube PDP-8 implementation

Vacuum tube implementation of PDP-8/V using a Raspberry PI for memory and I/O devices.

Website: https://www.outerworldapps.com/pdp8v

To generate PCBs (can be run from a PC or a RasPI): cd netgen make cd ../modules make << generates unrouted ACL, ALU, MA, PC, RPI, SEQ boards

open each of the above in its directory in the kicads directory ... and route route route!
