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 throughout the museum. The chapters of that biography embody the makes use of manufactured from it, and the historic and interpretive tales it may be made to inform. This then is a biography of 1 merchandise that not too long ago 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 electronic 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 residing facility, and she or he needed to make a plan for this in depth 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 dying toll in america from Covid-19 was nearing 100,000, with a vaccine shot for me nonetheless months sooner or later. I used to be working from residence 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. companies—first IBM, then RCA, and eventually Xerox. The gathering wasn’t far-off, and maybe there was a manner 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 might be secure for me to overview 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’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 troublesome time for CHM. And as my colleagues and I’d ultimately uncover, Dunlop’s assortment provided a rare 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 the gathering in that New Hampshire storage, one merchandise intrigued me. It was an early video recording, made in 1968, that clearly had nice which 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 surface, together with an extended letter from him tucked inside. Each notes informed of an ingenious pc 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 tools to get well the recording. Because the tape rested in my fingers, I puzzled the identical factor—ought to I even acquire 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 possibilities and acquire it.
To get well the recording from the out of date tape, the museum turned to George Blood LP, an organization that makes a speciality of archival audio and video. Penny Ahlstrand
The Dunlop assortment began its new life within the museum, fastidiously rehoused into archival storage bins 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 among the audiovisual supplies in our assortment. Once I was consulted about priorities, one of many objects I chosen was Dunlop’s 1968 video recording. Might 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 companies, boasting an unlimited assortment of apparatus—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 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 dwell 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” offered 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 serious computing convention in San Francisco, displayed the options and capabilities of his group’s “oN-Line System,” generally known as NLS. The system included many parts 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 gadget, the pc mouse.
This exceptional 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 superb and available on-line as we speak.
The NLS was pushed by a specific 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 part of collectively into groups and organizations, immediately utilizing new computing instruments and approaches for creating and utilizing data, and in doing so, “augmenting human mind” to higher resolve advanced issues.
Dunlop’s video recording, it turned out, additionally contained an indication of one other superior computing system that additionally befell 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 slightly on the idea of rank. The system was generally known as the IBM Company Headquarters Data Heart, 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 exceptional 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 deal with this extraordinary development, Dunlop labored on what he and others there referred to as “administration data techniques”—pc techniques serving the informational wants of IBM managers.
As Dunlop famous in an unpublished discuss, IBM managers have been more and more embracing data processing within the type of the corporate’s personal timesharing pc merchandise. A number of inside IBM techniques gave customers distant entry to timesharing computer systems, with modified electrical typewriters serving because the consumer “terminals.” A classy messaging system allowed staff 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 techniques for storing paperwork and formatting them in advanced methods, with a single pc supporting as much as 40 typewriter terminal customers. Lastly, there have been what as we speak we’d name database techniques, containing details about the enterprise and the group, with a question language and monetary fashions, once more obtainable from the customers’ typewriter terminals.
IBM’s Government Warfare Room
As these techniques have been more and more adopted by what Dunlop referred to as “operational and center managers,” he led a sequence of initiatives to see if IBM might create terminals and administration data techniques that could possibly be productively utilized by IBM’s “prime executives.” The techniques would enable 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 immediately linked to real-time information, monetary fashions, and abstract paperwork concerning 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 interviews and surveys, he concluded that the failure was because of the executives’ “self-role idea.” They held themselves to be “very excessive standing” decision-makers who acquired data 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 prime administration. Nonetheless, those self same prime managers had observed that center managers across the agency had established “struggle rooms,” during which workers built-in data from all the assorted terminal-based techniques: messaging, textual content, and database. At IBM company headquarters, the highest executives needed a struggle room of their very own.
This need led Dunlop and others to create the IBM Headquarters Data Heart. Right here, “data specialists” would reply to inquiries by high-ranking executives. The specialists had entry to messaging, textual content, database, and monetary modeling techniques accessed by typewriter and CRT terminals, in addition to an array of printed supplies, microform holdings, and audiovisual supplies. In brief, the data middle was a reference library, staffed with reference librarians, of the kind that will change into commonplace within the Nineteen Eighties.
An previous recording with typed notes from Dunlop turned out to include a beforehand unknown 1968 demonstration of an IBM system referred to as the Government Terminal. Penny Ahlstrand
With the brand new IBM Headquarters Data Heart in place, Dunlop noticed the chance to run one other experiment in 1967-68, which he referred to as the “Government Terminal.” The lead data specialist within the data middle would sit at a video-mixing and management console, outfitted with a video digicam, microphone, and even lighting. In the meantime, the chief consumer can be of their workplace with their Government Terminal, a modified tv set with an audio and video connection to the console within the data middle.
The chief pressed a button to summon the data specialist and their dwell video picture to the display. Remaining unseen, the chief might then place an inquiry. The knowledge specialist would direct different workers within the data middle to assemble the suitable data to reply the request: Fashions have been run on CRT terminals, paperwork and information have been gathered on typewriter terminals, microform could possibly be loaded right into a video reader, paper paperwork could possibly be positioned on a video seize unit. As soon as the outcomes have been assembled, the data specialist conveyed all this data to the chief, slicing from one video feed to a different, guided by the chief’s curiosity and route.
Dunlop’s 1968 video demonstration of the Government Terminal and the Data Heart proceeds in three acts.
The primary 10 minutes of the video present the data specialist and different workers responding to an govt’s request, discovering and getting ready all of the supplies for video presentation, utilizing the typewriter and CRT terminals, and even partaking in video conferencing with one other worker:
The following 5 minutes present the chief utilizing the Government Terminal to obtain the outcomes and directing the show and circulate of the data:
The ultimate jiffy present the data 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 in the end grew to become of IBM’s Government Terminal and the Data Heart, as they seem to have left little to no historic traces past just a few 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 exceptional 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 setting 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 identical superior applied sciences could possibly 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 data, and taking motion.
Within the Data Heart at IBM Headquarters, in Armonk, N.Y., data 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 deal with advanced issues. For Dunlop, the Government Terminal was a solution to his query, “Can we make higher selections, at larger ranges, by higher data 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 enhancing 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.
