Thank you! Will try after I mount the PiDP on the wall this morning. Bob Roswell bros...@syssrc.com

Given the success of the pdp-1 assembler version of lightpen motion prediction, a more advanced

I mounted my display behind the speaker panel. I used this one: https://www.amazon.co.uk/dp/

I'll add this to the version in my repo. I don't have write access to the original repo, so

Great reference, thank you! >The article featured a bland white machine, the PDP-1A prototype

Interesting method of mounting. Do you know of any documentation for installation in between the
