Does anyone have front panel PCB dimensions and positions for all the UI components I could use? I can make a simple PCB design for each of the main areas (lamps, switch register, other switch groups) that will arrive at a few smaller PCBs, saving a ton of cost. I also have experience in LED display and switch matrix design so we won't need a thousand wires going everywhere when used with an emulator. For example, one USB cable for the entire front panel. There exists the amazing PiDP-8 ( http://obsolescence.wixsite.com/obsolescence/pidp-8) that has all of these items taken care of. But there does /not/ exist one for the PDP-8/e.

The purpose of this course is to teach the basic of computer design, build and Programing a computer they must build. This course is still a year down the road. I volunteer to accomplish the building of the prototype system using only the parts available at the time the orginal computer were built. The point of the build is, if a 70+ can sit down with the course material, and design and build a working model of the PDP-8i, the there is no excuse that each student attending the course, should not be able to accomplish the same task. 1. I would like to know if you still have your PDP-8i Front Panel still available? 2. What is the cost for the panel plus shipping to Tucson, Arizona? 3. I understands that you are attempting to re-manufacture the Switch Rocker Assembly? And possibly the PCB board for mounting the switches? a. If so, I would like to know status, and an estimated cost for a complete set? B. Would these items be compatible to with c&k 7000 u-frame series switches assembly? One other question I have is do you have any drawings that give both the dimensions and profile of the mounting frame? If so are they available? I want to Thank You for taking the time ahead of time in answering this E-mail. Respectfully; Ray Neal
