This photo is my amateur radio station in 1954. My interest in electronics and amateur radio would determine my career for the next 51 years.
Graduated from Oregon State University in 1963 after a 2 years of duty in the Navy.

|David Larsen 1957 computer school|
|David did complete the training|
While in training for the Navy at Remington Rand Univac I did manager to complete several courses of study.
This was my first experience with computers and it created a curiosity about computers that has lasted to this very day.
|David's First design project at VT|
This photo taken in 1968 was one of my first projects at VT. I designed some circuits that would take the output of a digital multimeter and print & punch out the information on paper tape using the ASR33 teletype. It may not seem like much now but data was read off a strip chart recorder and then manually digitized for computer entry before I designed this automated digital data logger. A few years later I did some consulting for IBM and Analog Devices and they both built and sold commercial products using my ideas.

Interfacing workshop 1970
This photo is one of the early workshops using a PDP-8L Minicomputer about 1970. I did not do this work alone and was joined by various faculty during the 31 years at VT. Some of my colleagues were professors Dessy, Rony and Field, Jon Titus & Chris Titus at the Blacksburg Group and others on various occasions.
|Outboards - digital teaching aids|
About 1974 I designed some very simple digital teaching modules and called them "Outboards". They were marketed by E & L Instruments of Derby, CT along with the Bugbooks and other products developed my colleagues at the Blacksburg Group.
A catalog page from E & L Instruments showing a few of the "Outboards" in 1975. E & L also sold most of the digital products developed by our "Blacksburg Group" - some of the products were Jon Titus's MMD-1 computer, Bugbooks, Outboards, and other digital teaching equipment. See more here "CLICK"

These folks are using the Outboards and powering the experiments with a 6 volt lanter battery.
That is me leaning over at the back of the room near the screen in 1974.
