EAI 680 Scientific Computing System, c1968

Last week I came across a stash of fabulous photographs in a folder labeled “Bio Medical Engr.” Only some of them are dated but they all seem to have been taken from roughly 1968-1970. Let’s start off the week with this beauty:

Is it an analog computer? Does anyone know who the guy is? Also, I’m hoping someone with better photoshop skills than I have can make out what it says on that piece of paper.

Bonus: I also heart elec.

  1. The Tektronix 561a oscilloscope dates from about 1969. More information here: https://physicsmuseum.uq.edu.au/oscilloscope-type-561a.

    This machine is at least part analog because of the programming plugboard. A lifetime ago I programmed a Univac 1004 via plugboard.

    Not to mention the Champion spark plugs….:)

    I can enhance it enough to recognize cursive in light pencil or ink, but no idea what it says.

  5. In the late 1970’s, I remember that bio-medical engineering (essentially Dr. Clark), had an analog computer. They also had a PDP-12, which was an laboratory computer which combined a PDP-8 and a LINC. It was very useful for data acquisition. The EAI 680 looks like an earlier design for the same purpose.


    The PDP-12 was sold from 1969-72, so it was probably already at Rice when I arrived in 1975.
