Latest source code (including wireless XU), see the Feb 2 blog post for more details:
Previous version (ok to keep using if you don’t need the wireless XU):
The gerber files for the shim board to connect CYC1000 to a PiDP-11 console (see CYC1000 page for more info):
The gerbers are according to Seeed’s design and cam job rules. I’m not sure if they work for other vendors – please check, and let me know if you need a different format.
For convenience, I’m putting up my base image of 2.11BSD here. It’s installed according to the page under the HOWTO section, and patches have been applied up to #469.
