I'll always remember the first time that I encountered the Burroughs 205. I was a freshman at the University of Portland in the fall of 1963. Father Duffy was my Calculus teacher and during a class that autumn, he mentioned that the University was looking for someone to help out in the computer center. Was anyone interested? Uncharacteristically for me in those days, I quickly raised my hand.

A couple of days later I approached the computer room door. Two classrooms on the first floor of the Engineering Building had been converted into a computer center earlier that year. General Insurance Company of America, based in Seattle, had donated to the University a surplus B205 system that pretty well filled about eighty percent of the space. A bit of office space took up the balance of the area. As I walked through the door into the actual computer room, I was greeted by the combination of electronic hum and rush of air conditioning that was typical of early mainframe computers.

University of Portland computer center director, Peter C.
Knobloch explains some of the finer points of programmingBurroughs recommended an area of about twenty by forty feet for a computer room. This gave plenty of space to spread out the several refrigerator-sized cabinets that made up a computer in the 1960s.
The U of P computer room was pretty typical of mainframe installations at the time. The computer stood atop a four-inch thick raised floor. The floor served two purposes. First, it provided room to run the thick cables that interconnected the computer and its peripheral devices such as the IBM 407 accounting machine that served as a printer. Second, it served to allow the movement of cool air from the air-conditioning system into the bottoms of all the cabinets that were filled with heat-producing vacuum tubes.
The Datatron was already obsolete. With a 1954 introduction date, this was a nine year old design, and that was the reason that General Insurance was happy to part with it. But the computer still had plenty of life in it for educational and some administrative purposes.
For the University of Portland to have its own computer on campus was quite a
mark of distinction. We were a Catholic liberal arts university with
slightly over two thousand students. Our downtown state college rival,
Portland State College, couldn't boast of its own computer for educational purposes although it had a great
programming instructor, Dr.
Robert Broussard, who utilized another Datatron. Miles to the south,
the distinguished engineering school of Oregon
State University could only point to its ALWAC III-e, a machine of
comparable age, power and design.
The Datatron, From Consolidated Engineering to Burroughs
The Datatron has a fascinating background as it evolved from a "skunk works" project in the back room of an electronics instrument company in southern California to become the backbone of the Burroughs Corporation's tardy move into computers.
Consolidated Engineering Corporation (CEC) was a well established manufacturer of test instruments in the 1950s. Founded by Herbert Hoover, Jr., son of the former U.S. president, CEC developed test instrumentation for the petroleum industry. CEC was located in Pasadena and had a close working relationship with Cal Tech which included the presence of two Cal Tech faculty on the CEC board of directors. CEC developed a very successful line of Mass Spectrometers. Clifford Berry, as Chief Physicist at CEC held a number of patents in the Spectrometer field. Years earlier, Berry had been half of the Atanasoff-Berry team that developed the first rudimentary digital computer at Iowa State. (This machine was demonstrated to John Mauchly of ENIAC fame in 1941 and therein lies another chapter or two in everyone's modern day version of computer history.)
The major output of the Mass Spectrometer was data and lots of it. To produce the needed analysis, one had to solve a set of simultaneous linear equations. This required a lot of manual work with the calculators of the day. Cliff Berry and Sibyl Rock developed and patented an analog computer that produced excellent results solving a series of 12 simultaneous equations in 12 unknowns. This was now 1946 and this analog computer further cemented CEC's position in the Spectrometer business. As more years passed, Berry realized the potential for the digital computer to further enhance CEC's edge in his part of the business. He pressed CEC to develop their own digital computer. In 1951, CEC engaged Harry Huskey, then working on the National Bureau of Standards SWAC computer at nearby UCLA as a lecturer on digital technology to the project team.
Progress was relatively slow at first. CEC needed someone who could bridge the gap between Huskey and the design team. Another mathematician, this one an expert in number theory, the Norwegian Ernst Selmer, was lecturing at Cal Tech. Selmer had come to the United States to learn about electronic computing technology on an eighteen-month visit. He arrived in January of 1951 bound for Princeton where the IAS computer was being constructed for John Von Neumann. Selmer relates an amusing anecdote in this video as he describes his initial visit to the Institute. From Princeton, Selmer traveled to Berkeley where he contributed to the CALDIC computer being constructed by Paul Morton. He was hired by CEC management as a consultant late in 1951 and ultimately designed most of the logic for the Datatron.
By May of 1952, Chief Engineer, L. P. Robinson, was able to describe the Datatron (then known as the CEC 30-201) as part of a Navy symposium at the Pentagon on "Commercially Available General-Purpose Electronic Digital Computers of Moderate Price." To describe the Datatron as "commercially available" at this point was a bit of a stretch. It would be a full year until the first "breadboard" version of the machine was complete and over two years until the first production unit shipped.
Datatron Breadboard as it appeared in the 1952 CEC Annual Report
While the technical team went about engineering the computer, CEC management had other worries. They understood that the computer business was far different from the instrument business that they were in. In 1952, they designated the development group as a separate Computer Division and during the summer of that year the team of about thirty people moved into a vacant market building at 717 North Lake Avenue in Pasadena.
Realizing that the continued development of the CEC computer was going to take a great deal of money, CEC management decided to spin off the Computer Division as a separate corporation but retained a thirty-six percent ownership in the new company, ElectroData Corporation. ElectroData went public on the American Stock Exchange at $3.50 a share in April of 1954. It would rise as high as $21 in spite of a lack of profits.
Formal announcement of the ElectroData 203 computer took place in February of 1954. In April of 1954, the New York Times noted the introduction of a new "electronic brain" by ElectroData at the bargain rate of about $125,000. During 1954 ElectroData was running ads in Fortune promoting their Electronic Data-Processing Equipment for Science, Industry and Commerce. In June of 1954, the first production model shipped to the nearby Jet Propulsion Laboratory at Cal Tech. A total of seven systems were shipped in 1954 followed by thirteen more in 1955. The production line was humming.
ElectroData Production Line in 1955
Since competitive pressures required that computer be available via lease, costs continued to mount, however, and revenue was comparatively slim. The new corporation had outgrown their first home and moved to a larger facility at 460 Sierra Madre Villa, still in Pasadena. In early 1956, Phillip Fogg, Chairman of CEC set up a board meeting to consider the future of his ElectroData computer operation. ElectroData had now become the third largest manufacturer of computers in the world! Fogg and the board realized that while they had an excellent product, continued development, sales expense and rapid growth were going to require about $60 million over the next five years. This was twice the net worth of CEC. CEC/ElectroData was on the verge of throwing in the towel.
As fate would have it, that very day a phone call came in from John Coleman, the president of Burroughs Corporation. Now, Burroughs was a significant manufacturer of office computation equipment. That meant primarily mechanical adding machines and banking equipment at the time. Anyone who ever had to move one of these beasts from one table to another knows that if they were priced by the pound, Burroughs was probably doing all right financially. Realizing that office calculation was going electronic, their first venture into the marketplace was a timid one with a specialized machine lacking a stored program architecture, the E101, rather than a General Purpose computer. They found their customers saying, "No thanks, we are going with a full General Purpose computer."
As Burroughs management looked around for a way to jump start their entry into the computer field, they spotted ElectroData. On July 1, 1956 Burroughs purchased ElectroData Corporation from CEC in a stock swap with one share of Burroughs at $34 a share for each two shares of ElectroData.
Regardless of whether you see reference to the Datatron as a CEC 30-201,
CEC 30-203, an ElectroData 204 or 205, or a Burroughs 205, it is all the same
machine. The numbers primarily signify the development and addition of new
peripherals. The CEC 30-201 described at the Pentagon had only paper tape
input and Flexowriter output. That machine had the same architecture,
clock cycle and performance as the later Burroughs 205. While the 201 only had
34 instructions, most of what was added later were instructions to handle the
Tape, Cardatron and Floating Point units.
What Made the Datatron Special?
It seems that almost everyone who encountered the Burroughs 205 and continued
their involvement with computers developed a real affection for the
machine. There are reasons for this, of course.
- It Was Innovative
- B-Register The Datatron is generally recognized as the
first computer to be marketed with an index register. There are
references on the Internet to this register being named for
Burroughs. Since the register was named about five years before
Burroughs acquired ElectroData, in fact, even before ElectroData was
spun off from Consolidated Engineering, we can pretty well dismiss that
theory. In fact the B-Register's origins lie in England. The
University of Manchester had developed the index register concept for
the Mark I (also known as MADM) in 1949 and named it the B-Box to
distinguish it from the accumulator, or A-Box. Mathematician, Harry Huskey, was
aware of the B-box because he had contacts at Manchester built up during a one-year
appointment in England during 1947 where he worked under Alan Turing at
Teddington on
the ACE computer. He introduced the index register concept to the Datatron design
team where Ernst Selmer immediately grasped the importance. The
B-register served two purposes. The first was to provide address
modification and looping countdown. A more interesting purpose was
that the B-register could be utilized during program loading and that
allowed subroutines to be written with relative addressing. This
provided for easy relocation of subroutines, a godsend to scientific and
engineering calculation programs.
- High Speed Drum Access Technique. There were three
techniques that computer manufacturers used to deal with the fairly slow performance of a magnetic
drum as main storage. One was to simply spin the drum
faster. This puts limits on the size of drum and total memory
capacity suffers. A second technique was to use a system in which
each instruction specifies the address of the subsequent instruction
allowing optimum performance but making the programming quite
difficult. The Datatron used a third technique which placed a read
head one-tenth of a revolution apart from a write head and thus created
a sort of magnetic delay-line with access ten times as fast as the main
memory on the drum. This introduced some programming complexity
but not nearly as much as the previously described method.
- Ease of Programming. Customers noted three features that
made the Datatron easy to program. First was its use of the binary-coded-decimal
number system. Programmers and operators were looking at ten-digit
decimal numbers, where each digit was represented by a four bits having
the values of 1,2 4 and 8. Second was the presence of a breakpoint
switch on the console. Setting this switch allowed pre-coded
stopping points in the program to become active, halting the machine for
a readout of the registers. "Step Mode" allowed
execution of the program instructions, one at a time while observing the
results. The combination of step mode following a breakpoint,
allowed a programmer to follow the program flow in a style not
frequently seen until the introduction of the personal computer.
- Floating Point Arithmetic. The Datatron was optionally
equipped with hardware for floating point arithmetic. Implemented
by John Alrich, this was a refrigerator-sized cabinet that was attached
to the left end of the otherwise symmetric cabinet that made up the
Datatron CPU. With this option in place, the Datatron could handle
ten-digit numeric computations or floating-point numbers with an eight
digit mantissa and two digit exponent. With full multiply and
divide capabilities the Datatron now could handle numbers ranging from
10-49 to 1050 When Alrich first encountered his
new marketing Vice President, Ed McCollister, McCollister told him that
the new cabinet was not worth its weight in gold, it is worth its weight
in diamonds. This box would give ElectroData and later Burroughs
access to the scientific engineering market as well as the commercial
market they were initially targeting.
- Tape subsystem. The three-quarter inch wide magnetic
tapes used on the Datatron had individually addressable blocks of
data. A single tape held two sets of tracks, each with ten
thousand blocks. Each block contained twenty words of data.
With five alphanumeric characters in a word this gave you a maximum of
two million characters of data on a reel of tape. Not much by
today's standard. But in those days, we would look at it as
containing twenty-five thousand IBM cards and that is a stack almost
seventeen feet tall. That was a lot of student records, utility
bills or insurance records. The beauty of the Datatron tape system
was that it could search for a block of data on the tape without
stopping to wait. The CPU would give the tape controller a command
to search for block 4963 and the tape controller would handle the
job. The CPU just had to check back periodically and see if the
block was found yet. Up to ten tape drives could be hung on a
system. When a block was read into memory, it could be modified
and written back out onto the tape. (Yes you might want to make a
backup before beginning this type of update!)
-
Datafile subsystem. One of the more remarkable peripherals ever developed for any computer. It was the brainchild of Duncan MacDonald who would later go on to become Director of Engineering and then General Manager at Pasadena. This was a random access device. Remember, the disk drive had not yet been invented and drum memory was frightfully expensive. Tape access was relatively slow. It would take about eight minutes to move to the end of a reel of tape. What the Datafile did, in effect, was to take five reels of magnetic tape and split it up into fifty small chunks. These were suspended parallel to one another in a large bin (Some called it a coffin) and could be addressed individually. Any of the one hundred thousand blocks could be accessed in an average of sixteen seconds. You could think of it as a disk drive with one hundred tracks but revolving very slowly at about two revolutions per minute. Put ten of these Datafile systems together and you would have random access to any of one million blocks of data. This was the key to to the door for Burroughs entry into several insurance companies who bought Datatrons. When introduced in December of 1956, Burroughs claimed a backlog or orders totaling $2 million for the $75,000 device.

- Cardatron subsystem. The input and output of data on the
Datatron was handled by conventional IBM punched card accounting
machines. In most cases an IBM 089 Collator served as card reader
and an IBM 407 Accounting Machine served as the printer. The
Cardatron Subsystem on the Datatron allowed a programmer to pre-program
and load a "format band" for the printer that handled spacing,
zero suppression etc. The programmer could subsequently send a
string of perhaps thirty characters to the Cardatron system that would
be spaced appropriately across the printed line. While the
Cardatron and printer were handling this line, the Datatron was
calculating and preparing the next line.
- B-Register The Datatron is generally recognized as the
first computer to be marketed with an index register. There are
references on the Internet to this register being named for
Burroughs. Since the register was named about five years before
Burroughs acquired ElectroData, in fact, even before ElectroData was
spun off from Consolidated Engineering, we can pretty well dismiss that
theory. In fact the B-Register's origins lie in England. The
University of Manchester had developed the index register concept for
the Mark I (also known as MADM) in 1949 and named it the B-Box to
distinguish it from the accumulator, or A-Box. Mathematician, Harry Huskey, was
aware of the B-box because he had contacts at Manchester built up during a one-year
appointment in England during 1947 where he worked under Alan Turing at
Teddington on
the ACE computer. He introduced the index register concept to the Datatron design
team where Ernst Selmer immediately grasped the importance. The
B-register served two purposes. The first was to provide address
modification and looping countdown. A more interesting purpose was
that the B-register could be utilized during program loading and that
allowed subroutines to be written with relative addressing. This
provided for easy relocation of subroutines, a godsend to scientific and
engineering calculation programs.
- It Had a Good Pedigree
- Cliff Berry of the ABC, Atanasoff-Berry-Computer, the predecessor to
all electronic computers. Berry was a senior scientist with
Consolidated Engineering specializing in the design of Mass
Spectrometers, Consolidated's principal product line. He was the
driving force behind Consolidated's venture into computers. He
and a colleague had earlier patented an analog computer for use in
handling the large amounts of data coming from his Mass
Spectrometers. Although he was not officially on the design team,
he sat in on the lectures by Selmer and Huskey that introduced
Consolidated's designers to the digital computer.
- Ernst Selmer, a Norwegian mathematician specializing in number
theory and cryptography. Selmer had spent time at Princeton working with
Von Neumann's group on the IAS computer in 1951. The IAS was the
fastest computer in the world when it was fully operational in
1952. Selmer had later moved out to California and in early 1952 and
was a visiting lecturer in the mathematics department at Cal
Tech. He also had consulted at Berkeley where he designed the
add-subtract control for the CALDIC. He was
recommended to CEC management by Von Neumann and ended up designing much
of the Datatron arithmetic unit. While Selmer is a very key player
in the Datatron development, he is difficult to research outside
of his Datatron role since his cryptographic work was so secret that he
was not allowed to even report his consulting income to the Norwegian
tax authorities.
- Harry Huskey, an American mathematician who had worked on the ENIAC
and EDVAC projects at the University of Pennsylvania, worked at
Teddington England with Alan
Turing in 1947 on the prototype Pilot ACE computer. He later moved to California and
designed the SWAC computer for the National Bureau of Standards on the
UCLA campus. Completed in July 1950, the SWAC was the fastest
computer in the world until Von Neumann's IAS computer was
completed. Huskey's contributions to the Datatron were of a
general educational nature for the design team.
- Ida Rhodes,
one of the pioneers of the computer industry. Better known for her
role with the SEAC at the National Bureau of Standards and work with the
Univac at the Census Bureau, Rhodes was another consultant hired by CEC
during late 1952. She suggested the Breakpoint technique that was
ultimately incorporated into the Datatron. Gerturd
Blanch, Ida Rhodes' mentor was also directly employed by CEC for a
few months in late 1953.
- Frederic
G Withington, later a noted author and industry consultant,
wrote the Cardatron manual. He describes that first assignment in
an article here. (Since that link leads you to the IEEE's $19
electronic brick wall, I'll quote a bit of it for you.)
As soon as I had reported, he said, Write the Cardatron manual. I wondered, how do you write? and whats a manual? and verbalized the question whats the Cardatron? He said, Find out from the design engineers and let us know.
- Cliff Berry of the ABC, Atanasoff-Berry-Computer, the predecessor to
all electronic computers. Berry was a senior scientist with
Consolidated Engineering specializing in the design of Mass
Spectrometers, Consolidated's principal product line. He was the
driving force behind Consolidated's venture into computers. He
and a colleague had earlier patented an analog computer for use in

Spectrometers. Although he was not officially on the design team,
he sat in on the lectures by Selmer and Huskey that introduced
Consolidated's designers to the digital computer.
- It Did the Right Stuff - Perhaps Being A Bit of a Publicity
Hog too.
Now, as you read this, you might wonder what kind of people put all this publicity together? Fred Withington was not the only writer who was an ElectroData employee. Bob Forest, who would later become the renowned editor of Datamation magazine was hard at work under the direction of public relations manager, Dick Behm. Behm would also later serve at Datamation. Bill Rolph and Ray Hannon also moved into Datamation. For more on these figures here are a Forest biography and an article on the glory days of Datamation. (Yes both of those links lead you to the IEEE's $19 electronic brick wall.)
- On Friday night, December 30 of 1955, the Datatron forecast the
results for the five major bowl games. It correctly forecast the
winners of the Rose, Orange, Sugar and Cotton bowls and the results were
announced on the 6:15 newscast of KCOP-TV, channel 13. The only
miss was on the Alligator bowl where the Datatron had forecast a
tie. This is most likely the first widely disseminated
"computer prediction" for a sports event.
- In 1956 it is credited with composing the first computer-generated
melodies. The composition, "Push-Button Bertha" with
lyrics by composer Jack Owens was featured on KABC-TV in Los Angeles
- In 1957 it was the star of the show, playing blackjack as CalTech
showed off their Electronic Brains."
- In 1957 it translated the headlines in Pravda from Russian to English.
- On February 28, 1957, the New York Times introduced the new Standard
& Poor 500 Stock Index calculated hourly in Boston on a the
Datatron 205. A second article about the new average mentioning
the Datatron appeared on March 5. (The S&P was at 44.06)
- In 1961 during the first launch of a Saturn rocket, the Datatron 205
analyzed real-time guidance data from a tar-paper shack at Cape
Canaveral.

- It Had a Great Name
- Datatron Say it out loud! Even the later Burroughs
models had this name emblazoned on the CPU cabinet. And the name
has an interesting origin. In 1954, planners at IBM had begun
looking at a new machine that would unify their commercial and
scientific machine architectures. The proposed new system was
defined in a series of thirty-eight memos and with a project name of Datatron.
Shortly after this system was shelved, ElectroData hired IBMer, Ed
McCollister, in early 1955 to head the marketing division for their new computer.
He brought the name with him.

What Made a Datatron Installation Successful?
Success or failure of an individual Datatron site depended largely on the capability of the maintenance staff. Known as "Field Engineers" based on CEC's earlier designation, these intrepid folks had to master and in some cases invent techniques for minimizing the frequency and duration of machine outages. On a separate page I have described some of these techniques as practiced by one of the best.
