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!

IOW100Paddle: common questions

How big is the IOW100Paddle PCB?

The IOW100Paddle measures 83.8 × 167.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the IOW100Paddle?

106 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the IOW100Paddle design files?

From the mrieker/pdp8v repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IOW100Paddle design in my own project?

The repository has no license, so all rights stay with mrieker. Use it as a reference, and ask the author before reusing the design.
