Surprisingly, I can. It is a Tektronix 561A, with non-Tektronix plugins (probably connected through the back of the instrument): https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcQzHRwchWaaWZKs1_qjVGMwDxdTnL9rO9n81pcc-F02xDxpDxyX&usqp=CAU Here's another picture of the same LINC computer as the New York Times article: https://en.wikipedia.org/wiki/LINC ... with the same woman, Mary Ann Wilkes, at her home in 1965. One of the first home computers, which is //pretty damned cool//. The rectangular CRT and narrow plugins distinguish it from older 500 series oscillopscopes, and the knob placement on the right of the display narrow it down. There are many oscilloscopes (and photos of them) at the Vintage Tek museum: https://vintagetek.org Also manuals at http://w140.com/tekwiki/ I identified the 561a from the manual pdf at that website. I used debris from a 561 and other electronics scrap to design and build my first oscilloscope during high school. If I had known about Mary Ann Wilkes at that time (circa 1970), I would have developed a secret adolescent crush on her ... but mostly on her computer, sending circuit boards rather than flowers. Keith P.S. The vintageTek museum (on the Tektronix Beaverton campus) is shut down for COVID. When/if it reopens to the public, it will be open for guided tours on Friday and Saturday afternoons. Full-immersion geekiness; worth a visit. Most of the volunteers are old, and a very few are Fox-noisy; I hope they survive lethal misinformation. -- Keith Lofstrom [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
