DECwriter Printing Terminals
DECwriter II LA36
(The LA-120 looks the same but 120 cps)
Dot matrix, 30 cps
char./inch horizontal, 6 vertical
Char. matrix: 7x7
Char. set: Complete US
ASCII (128 codes)
63 in ANSI X4.14-1971 typewriter layout
Aux. keypad: 19 keys (digits, arrows, function
Decwriter Printing terminals were the 'modern'
replacement for the Teletype KSR 33 in many offices that were
connected to timeshare computers. The LA36 DECwriter II was the company's first commercially successful keyboard terminal and became the de facto market standard.
The LA-36 utilizes all solid state logic and has an electronic keyboard. The only mechanical components are the 9-pin print head, the print head motion mechanism, and the paper line feed hardware.
The DECwriter progression
The DECwriter II -30 cps, also known as the LA36, is the second in a
series of printing terminals by Digital
Equipment Corporation, being introduced in 1974.
There are two versions, one with a keyboard and several switches,
called the LA36, and one with just the printing assembly and less
switches, designated LA35.
It was preceded by the DECwriter 30 cps in 1970.
It is succeeded by the DECwriter III in 1978.
The DECwriter IV, also known as the LA38, is the last in a series of
printing terminals by Digital Equipment Corporation, being introduced in
There are two versions, one with a keyboard and several switches,
called the LA38, and one with just the printing assembly and less
switches, designated LA34.
The DECwriter IV models ended the floorstanding design of the previous
DECwriters and are tabletop models, about the size of a large typewriter.
The DECwriter IV was the last of DEC's printing terminals.
History of the DECwriter III At SMECC
Ben Cohen tells us, "The DECwriter III was donated sometime in probably the early 90s by Honeywell to Community Information and Referral (http://www.cir.org/), a Phoenix nonprofit that maintains a database of community, state, and local services and a call center to help people find those services. The
DECwriter III was connected to a VAX 11/750 until 1995 when then VAX was replaced with a Sun
server running Sybase." - SMECC

A Chemical Teletype
of Chemical Documentation, 13, 2, 53-56, May 73
A Teletype Model 37 machine has been modified for the coding of
chemical structures. The coding rate of this model is higher than
that of other machines of this type. The rationale for choosing this
particular type of input equipment is presented.

|Virgil Bradshaw, 77; developed
Associated Press LaserPhoto
By Jack Williams
September 18, 2004
Virgil Bradshaw's idea of bringing The Associated Press up to speed was
the revolutionary LaserPhoto system.
As deputy director of the wire service's communications department in the
1970s, he introduced a breakthrough technology that, by processing photos
with heat, produced higher-quality images that could rapidly reach news
"Before that, the photos were transmitted slowly on a photo fax
machine and they were grainy in quality," said Patrick Bradshaw, Mr.
Bradshaw's son and chief of communications for AP in Indianapolis.
When Mr. Bradshaw retired from AP in 1985, he moved from New Jersey to
Ramona, where he became managing editor of the monthly San Vicente
He died Sept. 10 of complications from a stroke and congestive
heart failure at his Ramona home, his son said. He was 77.
In the competitive world of wire services, Mr. Bradshaw always looked
for an edge. "He was a driving force at AP in keeping it ahead of the
game," Patrick Bradshaw said.
In developing the LaserPhoto technology, Mr. Bradshaw consulted
professors and students at the Massachusetts Institute of Technology to
refine the concept and create a prototype. He then enlisted a Florida firm
to begin production.
The system entailed processing with heat instead of chemistry and the
application of a laser light source instead of conventional lamps.
AP updated the system in 1989 with computer technology that allowed
photos to be viewed on a computer screen.
Mr. Bradshaw, the son of an AP Teletype operator, was born in Hannibal,
He left his job as an AP copy boy in Kansas City, Mo., to join the Navy
during World War II. He served overseas as a yeoman third class, with a
specialty in journalism, aboard the destroyer escort Emery.
After the war, Mr. Bradshaw attended Rockford College and resumed his
job with AP in Kansas City, working his way up to Teletype operator.
He became chief of communications in AP's St. Louis office and
continued in that capacity in Indianapolis and Chicago. When he became
deputy director of communications, he oversaw chiefs in each AP bureau and
negotiated union contracts.
Seeking a milder climate, Mr. Bradshaw and his first wife, Mary, moved
from Matawan, N.J., to San Diego Country Estates after his retirement.
The idea of writing and editing appealed to him after a career on the
technical side of the news industry. So he began contributing photographs
to the San Vicente Valley News.
Before long, he was supervising a small staff, covering community
news and writing editorials. As the health of his wife began to
deteriorate before she died of cancer in 1995, he cut back on his
"The newspaper was a passion for him, and he enjoyed it
immensely," Patrick Bradshaw said. "He was always a bit of a
workaholic – always had to be doing something or going somewhere."
Despite the demands of his AP job, he always found time for his eight
children. "He never missed any of our games," son Mike Bradshaw
said. "Everybody played different sports in high school, and somehow
he was there for us."
A sports enthusiast, Mr. Bradshaw had played football in high school
and had umpired in a semiprofessional baseball league. He was an avid
hunter and tennis and table tennis player.
Survivors include his second wife, Perdita; daughters, Debbie
Gasikowski of New Jersey, Mary Murphy of Denver and Annette Bradshaw of
Escondido; sons, Mike Bradshaw of San Diego, Steve Bradshaw of New Jersey,
Patrick Bradshaw of Indianapolis, Tim Bradshaw of New Jersey and John
Bradshaw of Washington, D.C.; and 20 grandchildren.
Services were Wednesday at Immaculate Heart of Mary Catholic Church,
Ramona. Interment was at Nuevo Memory Gardens, Ramona. Donations are
suggested to the Elizabeth Hospice, 150 W. Crest St., Escondido, CA 92025
or Immaculate Heart of Mary Catholic Church, 537 E St., Ramona, CA 92065.

|Doug offers the following insight into Teletype
Often in discussions of Teletype Corpration modules used in encryption
gear or in associated equipment we run into designations such as "LTPE".
The system used is curious, and "just growed", leading to some
curiosities, to say the least.
Let me mention first that on gear made by Teletype for the Bell Telephone
System, this system of codes was not used but rather a different one. As a
result, many people whose experience with Teletype gear was wholly though
work in the Bell system may have never, or only incidentally, encountered
this apparatus code system.
Except for some very ancient gear, the "apparatus codes" begin
with a letter indicating the "model number family" of the gear.
For the Model 28 family (and in fact Model 35 as well), that letter is
For the model 15 family that letter was "B"; for the Model 14
family, it was "F".
Following that was an alphabetic code that, somewhat mnemonically,
identified (functionally) the specific unit. For a keyboard, it was
For a typing unit (printer) it was P for a page printer, if the
family was page printer oriented (B or L), or a tape printer if the family
was tape oriented (F).
But if the family was page-printer oriented, then for the tape printer
it was TP. (T for "tape".)
For a perforator (mechanical input, usually from a keyboard), the
code was PE. If it also printed on the tape (a typing perforator),
it was TPE. (T for "typing" - oh, great!.)
For a signal-driven punch (a reperforator), the code was RP. If it
printed on the tape (a typing reperforator), the code was PR (P for
printing; yes, that is exactly the same thing as "typing". So
why not "T"? Well that could be confusing in certain cases.).
For tape reader that sent out a serial teletypewriter signal (a transmitter-distributor,
referred to colloquially as a "TD") the code was XD (X for transmit).
If a transmitter-distributor was closely integrated with a typing
reperforator (and the transmitter usually had a swinging head so it
could send out the last character punched), the consolidated unit had the
code RXD. (No letter to tell us that it was typing? No.)
If a transmitter-distributor was closely integrated with a perforator,
keyboard-driven, most often non-printing (again, the transmitter usually
had a swinging head so it could send out the last character punched), the
consolidated unit had the code PEX. (What about the
"distributor" function. Well, that was assumed.)
Back to the Bell System notation. A specific configuration Model 28
keyboard known inside Teletype Corporation as, for example (and I am just
making these up) LK51B might be known (and indicated on teh nameplate) in
teh Bell System as a 28J2.
Items such as cabinets and colors has paint color suffixed, again
different between Teletype and the Bell System. The only one I remember
just now (maybe) was that the standard green crackle finish for Model 28
items was "AB" in the Teletype coding system and "-40"
in the Bell System coding system. (And I may in fact remember that wrong -
its been a long time!)
And so on and so forth.
Aren't you glad you asked! Best regards, Doug
are 2 UPI teletypes next to each other in the news room.. why?

jfk history.... good history of journalism history.
I think I can give an educated guess,
but only from the AP side.
There were one or two TV stations in the North Carolina coverage which had
the M-20 service, normally for the newspapers, in addition to the M-15
service, which was the radio wire service.
Bear in mind, I've not really given this a lot of thought for 40 years or
so, so I might be a bit hazy.
I am thinking there were at least three slow speed 6-level wire services
in the state for the newspapers. One was the AM cycle, for the
morning newspapers, the second was the PM cycle, for the afternoon
The third 6-level service, if memory serves me correctly, was loaded with
feature stories and expanded news stories which weren't quite as time
sensitive as the AM and PM cycles.
Was there one or more other 6-level services in the North Carolina AP
service coverage? I Just can't remember.
Bottom line, I'd suspect the TV
station simply wanted more news than the radio wire could supply, either
in volume or depth.
