It appears to me that each merchandise within the
Computer History Museum’s assortment has a biography of kinds—a life earlier than CHM, a story about the way it got here to us, and a life inside the museum. The chapters of that biography embody the makes use of product of it, and the historic and interpretive tales it may be made to inform. This then is a biography of 1 merchandise that just lately entered the museum’s assortment—an early Memorex videotape containing a recording from 1968—and the historic discovery it has afforded.
Our biography begins in Could 2020, with an e-mail. Debra Dunlop, a
dean at New England College, wrote to the museum about a big assortment of paperwork, audiovisual supplies, and a uncommon pc, a Xerox Star, in New Hampshire. These have been the skilled papers of Debra’s father, Robert Dunlop, and she or he knew how dearly he valued the gathering. She was serving to her father transfer to an assisted dwelling facility, and she or he needed to make a plan for this intensive assortment. What did the museum suppose?

For me, the Dunlop assortment was a light-weight within the darkness. It was nonetheless early days within the pandemic, and the demise toll in the US from Covid-19 was nearing 100,000, with a vaccine shot for me nonetheless months sooner or later. I used to be working from house in Massachusetts however I used to be nervous as a result of the museum—like all locations that rely partially on ticket gross sales—confronted strong financial pressures, and I didn’t understand how lengthy it might go on with its doorways closed. The Dunlop assortment sounded attention-grabbing. Robert Dunlop had been an industrial psychologist who spent his profession at massive, high-technology U.S. corporations—first IBM, then RCA, and eventually Xerox. The gathering wasn’t distant, and maybe there was a method I might safely go and take a look.
I realized extra about Robert Dunlop’s profession from Debra. She and her household moved the gathering to a storage the place, after we let it sit for per week, we felt it could be secure for me to evaluate the supplies alone, carrying a masks, with the storage doorways open.
After the go to, I mentioned what I had seen with my colleagues, and we agreed that I might return and choose, pack, and ship out a considerable portion of it. Debra and her household very kindly made a monetary donation to the museum to assist with the delivery bills in that troublesome time for CHM. And as my colleagues and I might ultimately uncover, Dunlop’s assortment provided a unprecedented glimpse right into a transformative time in superior computing, and a captivating mission that had been wholly unknown to the history of computing till now.
A Discovery

As I went by means of the gathering in that New Hampshire storage, one merchandise intrigued me. It was an early video recording, made in 1968, that clearly had nice that means for Robert Dunlop. The 1-inch format tape on an open reel had been fastidiously packaged and included an explanatory notice by Dunlop taped to the skin, together with an extended letter from him tucked inside. Each notes advised of an ingenious pc system at IBM headquarters that I’d by no means heard of. In keeping with the notes, a demo of the system was captured on the lengthy out of date video.
In 1995, when Dunlop wrote the notes, he had despaired of discovering any working tools to get well the recording. Because the tape rested in my palms, I puzzled the identical factor—ought to I even gather this if it’s not possible to look at? However then I assumed, “Maybe we are able to determine one thing out. And if not us, possibly one thing might occur sooner or later.” I made a decision to take my probabilities and gather it.
To get well the recording from the out of date tape, the museum turned to George Blood LP, an organization that focuses on archival audio and video. Penny Ahlstrand
The Dunlop assortment began its new life within the museum, fastidiously rehoused into archival storage packing containers and added to our backlog for archival processing. In 2023, a grant to the museum from the
Gordon and Betty Moore Foundation introduced a possibility to digitize among the audiovisual supplies in our assortment. After I was consulted about priorities, one of many gadgets I chosen was Dunlop’s 1968 video recording. May we give it a attempt?
Massimo Petrozzi, CHM’s Director of Archives and Digital Initiatives, reached out to his networks to see if there was somebody who might assist. A contact in Europe pointed again to the States, to George Blood and his agency George Blood LP exterior of Philadelphia. The corporate is a significant supplier of audio and moving-picture preservation companies, boasting an infinite assortment of apparatus—together with, because it occurs, an Ampex video unit able to recovering video from Dunlop’s tape, which Blood known as a “very early expertise.” Blood and his colleagues made painstaking changes and experiments and have been lastly capable of get well and digitize Dunlop’s silent video, fulfilling Robert Dunlop’s lengthy hopes. Sadly, Dunlop didn’t stay to see his recording once more. He died in July 2020.
A Competing Imaginative and prescient of Computing
The recording reveals a narrative as attention-grabbing as it’s seemingly forgotten.
It’s possible you’ll already pay attention to the “Mother of All Demos” introduced by Doug Engelbart and the members of his Stanford Analysis Institute middle on the shut of 1968. This presentation, with Engelbart on stage at a significant computing convention in San Francisco, displayed the options and capabilities of his group’s “oN-Line System,” referred to as NLS. The system included many components that have been terribly novel, even for the assembled computing professionals: networked computer systems, video conferencing, graphical interfaces, hypertext, collaborative phrase processing, and even a brand new enter system, the pc mouse.
This outstanding 1968 demonstration of the NLS was, a lot to our profit, recorded on videotape. Though comparatively early in video expertise, the standard of the surviving recording is great and available on-line at this time.
The NLS was pushed by a selected imaginative and prescient for the longer term use and observe of computing: a imaginative and prescient that centered on the notion of alliance. On this imaginative and prescient, people would be a part of collectively into groups and organizations, straight utilizing new computing instruments and approaches for creating and utilizing data, and in doing so, “augmenting human mind” to higher remedy complicated issues.
Dunlop’s video recording, it turned out, additionally contained an illustration of one other superior computing system that additionally came about in 1968. This second demo occurred on the East Coast, at IBM’s company headquarters in Armonk, N.Y., and was motivated by a far totally different—maybe one might go as far as to say an reverse—imaginative and prescient for the way forward for computing. This imaginative and prescient centered not on alliance, however reasonably on the idea of rank. The system was referred to as the IBM Company Headquarters Info Middle, and it was the fruits of Dunlop’s experiments with executive-computer interplay on the firm.
Dunlop’s profession at IBM throughout the Nineteen Sixties coincided with a very outstanding interval of progress for the agency. From 1964—the 12 months IBM introduced its
new System/360 line of digital computers—to 1970, the agency’s headcount and revenues each doubled.
To take care of this extraordinary progress, Dunlop labored on what he and others there known as “administration info methods”—pc methods serving the informational wants of IBM managers.
As Dunlop famous in an unpublished discuss, IBM managers have been more and more embracing info processing within the type of the corporate’s personal timesharing pc merchandise. A number of inner IBM methods gave customers distant entry to timesharing computer systems, with modified electrical typewriters serving because the person “terminals.” A complicated messaging system allowed workers to ship each other telegram-like messages from one terminal to a different, on the price of 25,000 messages per day. A mathematical utility, QUIKTRAN, let customers carry out easy in addition to refined calculations from their terminals. There was a proliferation of methods for storing paperwork and formatting them in complicated methods, with a single pc supporting as much as 40 typewriter terminal customers. Lastly, there have been what at this time we might name database methods, containing details about the enterprise and the group, with a question language and monetary fashions, once more accessible from the customers’ typewriter terminals.
IBM’s Government Struggle Room
As these methods have been more and more adopted by what Dunlop known as “operational and center managers,” he led a sequence of tasks to see if IBM might create terminals and administration info methods that may very well be productively utilized by IBM’s “high executives.” The methods would permit the executives to make strategic selections for the corporate in new methods afforded by the pc. His preliminary efforts all failed.
First, Dunlop experimented with offering high-ranking executives—VPs and the like— with typewriter terminals straight linked to real-time information, monetary fashions, and abstract paperwork in regards to the agency. The terminals went untouched, shortly migrating to the desks of the executives’ secretaries.
Dunlop then tried utilizing IBM’s new CRT-based terminal, the 2250, with a simplified keypad for enter. The outcome was unchanged. By way of interviews and surveys, he concluded that the failure was as a result of executives’ “self-role idea.” They held themselves to be “very excessive standing” decision-makers who obtained info from subordinates; any direct use of a typewriter or keyboard would “demean” them.
From his failed experiments, Dunlop concluded that the state-of-the-art in computing expertise was insufficient for making a terminal-based administration system for high administration. Nonetheless, those self same high managers had observed that center managers across the agency had established “warfare rooms,” during which workers built-in info from all the assorted terminal-based methods: messaging, textual content, and database. At IBM company headquarters, the highest executives needed a warfare room of their very own.
This need led Dunlop and others to create the IBM Headquarters Info Middle. Right here, “info specialists” would reply to inquiries by high-ranking executives. The specialists had entry to messaging, textual content, database, and monetary modeling methods accessed by means of typewriter and CRT terminals, in addition to an array of printed supplies, microform holdings, and audiovisual supplies. In brief, the knowledge middle was a reference library, staffed with reference librarians, of the type that might turn out to be commonplace within the Eighties.

With the brand new IBM Headquarters Info Middle in place, Dunlop noticed the chance to run one other experiment in 1967-68, which he known as the “Government Terminal.” The lead info specialist within the info middle would sit at a video-mixing and management console, geared up with a video digital camera, microphone, and even lighting. In the meantime, the chief person can be of their workplace with their Government Terminal, a modified tv set with an audio and video connection to the console within the info middle.
The manager pressed a button to summon the knowledge specialist and their stay video picture to the display screen. Remaining unseen, the chief might then place an inquiry. The data specialist would direct different workers within the info middle to collect the suitable info to reply the request: Fashions have been run on CRT terminals, paperwork and information have been gathered on typewriter terminals, microform may very well be loaded right into a video reader, paper paperwork may very well be positioned on a video seize unit. As soon as the outcomes have been assembled, the knowledge specialist conveyed all this info to the chief, reducing from one video feed to a different, guided by the chief’s curiosity and path.
Dunlop’s 1968 video demonstration of the Government Terminal and the Info Middle proceeds in three acts.
The primary 10 minutes of the video present the knowledge specialist and different workers responding to an government’s request, discovering and getting ready all of the supplies for video presentation, utilizing the typewriter and CRT terminals, and even participating in video conferencing with one other worker:
The subsequent 5 minutes present the chief utilizing the Government Terminal to obtain the outcomes and directing the show and circulate of the knowledge:
The ultimate jiffy present the knowledge specialist engaged on an IBM 2260 video pc terminal, on the time nonetheless a novelty that was used for database and mannequin entry:
Restoring Historical past
It’s unclear what finally grew to become of IBM’s Government Terminal and the Info Middle, as they seem to have left little to no historic traces past a number of paperwork—together with the unpublished discuss—some pictures, and Dunlop’s 1968 video recording.
With Engelbart’s and Dunlop’s 1968 demo movies, we now have a outstanding and contrasting snapshot of two very totally different instructions in superior computing. Engelbart’s Mom of All Demos confirmed how superior computing might create a shared, collaborative atmosphere of allied people, all direct customers of the identical system, befitting of a laboratory of pc fans in Menlo Park, Calif. Dunlop’s Government Terminal demo confirmed what number of of those similar superior applied sciences may very well be directed alongside one other path, that of a strictly hierarchical group, extremely attuned to rank and outlined roles and specialties. Whereas these have been very totally different and maybe opposing instructions, they shared a standard dedication to the usage of superior computing for organizing and analyzing info, and taking motion.
Within the Info Middle at IBM Headquarters, in Armonk, N.Y., info specialists have been on name to reply questions from customers.The Dunlop Assortment
Engelbart held that his system was for the “augmentation of the human mind,” in order that customers may higher handle complicated issues. For Dunlop, the Government Terminal was a solution to his query, “Can we make higher selections, at greater ranges, by means of higher info processes?”
There are echoes of Engelbart’s Mom of All Demos round us every single day—the hyperlinks of the Net, the scuttling of pc mice on desktops, the modifying of on-line paperwork, and extra. However simply as evident are the echoes of Dunlop’s Government Terminal demo, such because the video conferencing and screen-sharing practices so acquainted in Zooms, Groups, and Meets at this time.
The Pc Historical past Museum is happy to make public the entire video recording of Robert Dunlop’s 1968 demonstration, and with its launch, to revive a forgotten chapter within the historical past of computing.
