BRAVO Herb; You are another scholar who again brought back memories for me. When EAI got too big for their britches, they got involved in full scope power plant simulators using SEL 32 mainframes and CDC Winchester drives. FORTRAN was the OS of the day on these mainframes modeling nuclear reactor vessels, and processes. I have a very good PHD friend living out in Hightstown, NJ who still uses FORTRAN from time to time in his modeling work. We worked together on the ANPP project out in AZ for AZ Public Service (back in the late 80's). I can drop him a line if he might be interested in helping in such a project. I helped him in showing him real life SCADA instrumentation dynamics so as he could get the software objects to respond and drive the instrumentation as fast as the real life analog processes did. ..... Not such an easy task. Count me as one who would want to see something similar run on big iron. I might be able to help with the peripheral instrumentation as well. If you are coming this weekend, we might talk further. Many Thanks for your continued "long view" insight for the mission statement. Bill Inderrieden In a message dated 5/5/2017 12:00:07 P.M.

The exhibit would be, a vintage computer running a FORTRAN program, which modeled some physical system - a chemical plant, an automobile engine, a nuclear power plant, whatever - and used some other computer or means (a reduced size model, etc.) to visually demonstrate what was being "computed"? An example of sorts, is David Gesswein's display at VCF-East 2017. He displayed graphical results (not the actual computations or the thing modeled) on graphical terminals and on paper with a plotter. It was a physically interesting exhibit, of these graphical instruments - that was the point, I understood that, I liked the exhibit. In short - is anyone interested in actual, useful *computations* from a vintage computer? And in seeing those results displayed in some simulation of a physical system? Or would such an exhibit, be lost among graphical games and videos? Or irrelevant among displaying the computers as various brands and models with this feature or that? Those are important considerations among vintage computer owners and visitors; so is what I'm talking about. Herb Johnson retro*technology*.com
