I want one…someday! The PDP 11/70 is what I started my computer career on. I first used it in college, where I also ran it as a tutor/operator. Here is a nice article about running RSTS/E on it. The PiDP-11 is a replica of the PDP-11/70. It’s smaller but the switches, colors and even the block “digital” brand recessed into the panel plastic…look to my eyes/memory exact. Here is a great picture. It uses a Raspberry Pi to emulate the PDP 11/70. I remembered the toggle switch settings to bootstrap the OS, probably at least 10 years after our company moved on to an IBM mainframe.
