It appears to me that each merchandise within the
Computer History Museum’s assortment has a biography of types—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 embrace the makes use of fabricated from 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 Might 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 laptop, a Xerox Star, in New Hampshire. These had 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 assume?

For me, the Dunlop assortment was a lightweight 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 dwelling in Massachusetts however I used to be nervous as a result of the museum—like all locations that rely partly 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 giant, high-technology U.S. corporations—first IBM, then RCA, and at last Xerox. The gathering wasn’t far-off, and maybe there was a manner I might safely go and take a look.
I discovered 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 will be protected for me to evaluation the supplies alone, sporting 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’d 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 tough time for CHM. And as my colleagues and I’d finally uncover, Dunlop’s assortment provided a rare glimpse right into a transformative time in superior computing, and an interesting undertaking that had been wholly unknown to the history of computing till now.
A Discovery

As I went by way 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 observe by Dunlop taped to the surface, together with an extended letter from him tucked inside. Each notes advised of an ingenious laptop system at IBM headquarters that I’d by no means heard of. In accordance 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 gear to get better the recording. Because the tape rested in my arms, I puzzled the identical factor—ought to I even acquire this if it’s inconceivable to observe? 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 acquire it.
To get better 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 containers and added to our backlog for archival processing. In 2023, a grant to the museum from the
Gordon and Betty Moore Foundation offered a chance to digitize a few of the audiovisual supplies in our assortment. Once I was consulted about priorities, one of many gadgets I chosen was Dunlop’s 1968 video recording. May we give it a strive?
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 outdoors of Philadelphia. The corporate is a serious supplier of audio and moving-picture preservation providers, boasting an infinite assortment of kit—together with, because it occurs, an Ampex video unit able to recovering video from Dunlop’s tape, which Blood referred to as a “very early know-how.” Blood and his colleagues made painstaking changes and experiments and had been lastly capable of get better 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.
Chances are you’ll already concentrate on the “Mother of All Demos” offered by Doug Engelbart and the members of his Stanford Analysis Institute heart on the shut of 1968. This presentation, with Engelbart on stage at a serious 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 had 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 know-how, the standard of the surviving recording is superb and available on-line as we speak.
The NLS was pushed by a selected imaginative and prescient for the long run 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, instantly utilizing new computing instruments and approaches for creating and utilizing information, and in doing so, “augmenting human mind” to raised clear up complicated issues.
Dunlop’s video recording, it turned out, additionally contained an indication of one other superior computing system that additionally happened 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 completely 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 fairly on the idea of rank. The system was referred to as the IBM Company Headquarters Info Middle, and it was the end result of Dunlop’s experiments with executive-computer interplay on the firm.
Dunlop’s profession at IBM throughout the Sixties coincided with a very outstanding interval of development 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 cope with this extraordinary development, Dunlop labored on what he and others there referred to as “administration info methods”—laptop methods serving the informational wants of IBM managers.
As Dunlop famous in an unpublished discuss, IBM managers had been more and more embracing info processing within the type of the corporate’s personal timesharing laptop merchandise. A number of inside IBM methods gave customers distant entry to timesharing computer systems, with modified electrical typewriters serving because the person “terminals.” A classy messaging system allowed staff to ship each other telegram-like messages from one terminal to a different, on the fee 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 laptop supporting as much as 40 typewriter terminal customers. Lastly, there have been what as we speak we’d 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 Warfare Room
As these methods had been more and more adopted by what Dunlop referred to as “operational and center managers,” he led a collection of tasks to see if IBM might create terminals and administration info methods that may very well be productively utilized by IBM’s “prime executives.” The methods would permit the executives to make strategic choices 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 instantly linked to real-time information, monetary fashions, and abstract paperwork concerning the agency. The terminals went untouched, rapidly 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 end result 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 know-how was insufficient for making a terminal-based administration system for prime administration. Nonetheless, those self same prime managers had observed that center managers across the agency had established “warfare rooms,” through which employees built-in info from all the varied 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 way of typewriter and CRT terminals, in addition to an array of printed supplies, microform holdings, and audiovisual supplies. In brief, the knowledge heart was a reference library, staffed with reference librarians, of the kind that will develop into commonplace within the Nineteen 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 referred to as the “Government Terminal.” The lead info specialist within the info heart 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 could be of their workplace with their Government Terminal, a modified tv set with an audio and video connection to the console within the info heart.
The manager pressed a button to summon the knowledge specialist and their stay video picture to the display. Remaining unseen, the chief might then place an inquiry. The knowledge specialist would direct different employees within the info heart to assemble the suitable info to reply the request: Fashions had been run on CRT terminals, paperwork and information had 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 had been assembled, the knowledge specialist conveyed all this info to the chief, slicing 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 employees 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 stream of the knowledge:
The ultimate jiffy present the knowledge specialist engaged on an IBM 2260 video laptop 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 completely different instructions in superior computing. Engelbart’s Mom of All Demos confirmed how superior computing might create a shared, collaborative surroundings of allied people, all direct customers of the identical system, befitting of a laboratory of laptop fanatics in Menlo Park, Calif. Dunlop’s Government Terminal demo confirmed what number of of those identical 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 had been very completely different and maybe opposing instructions, they shared a typical dedication to using superior computing for organizing and analyzing info, and taking motion.
Within the Info Middle at IBM Headquarters, in Armonk, N.Y., info specialists had 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 tackle complicated issues. For Dunlop, the Government Terminal was a solution to his query, “Can we make higher choices, at greater ranges, by way of higher info processes?”
There are echoes of Engelbart’s Mom of All Demos round us on daily basis—the hyperlinks of the Internet, the scuttling of laptop 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 as we speak.
The Laptop 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.
