Civil Defense film strips

Below are some representative images from some Civil-Defense 35mm film strips I purchased from Xerxes Books' 'atomic ephemera' list. Content-wise these filmstrips are utterly predicatable -- fallout, basics of radiation dosage, radiacs, decontamination, shelters, etc, ad nauseum. The graphical style is pretty nice though, typical of the era. Unfortunately the quality of the images here suffer f...

The Earth's Satellite

This is a 45 rpm vinyl record made of the Soviet Unions Sputnik satellite circling the earth, a sound recording made from earth. It doesn't sound like much but it changed the world....

Armed Forces Special Weapons Project (AFSWP), and Manhattan Project badge

Manhattan Project badge, ca. 1945. The Army designed a patch for their staff at the Manhattan Project in Los Alamos New Mexico, a rather childishly-rendered but scary image of a brain (with Army star) splitting an atom; typical Army graphic design for badges is usually quite good; they must have been in a hurry on this one. This description of the patch is from Associated Press: "WASHINGTON...

COLD WAR 1 U.S. INFORMATIONAL FILMS

This is the official distribution of WPS-approved informational films originally distributed by various branches of the U.S. government. They are to be shown only by and to approved personnel. The original 16mm films were professionally cleaned and transferred to 3/4" master tapes, from which VHS copies were made. All tapes are 120-minute VHS format only. Tape 1 (VHS1, 68 minutes) contains: N...

An assortment of Radiacs

Tom Jennings, 1997 revised, 6 Feb 2000 'Radiac', or sometimes 'radiacmeter', is the generic word for radiation detection and measurement equipment, in the context of human hazard avoidance. Pocket dosimeters, hand-held, permanently-fixed, mobile and other devices are included. I have no idea how I ended up collecting this stuff. Some of it is intrinsically interesting, some I bought to pilfer ...

Device test images from wxvax7.esa.lanl.gov

In the late 1990's LANL (Los Alamos National Laboratory) had a public web server running on what later turned out to be a classified machine. I don't think any security breach occurred, but one day the machine simply disappeared. I wrote to the webmaster (back when you could do such a thing) who told me an audit discovered this alarming state and it was shut down. Luckily I'm a packrat and occasi...





Computation

INPUT/OUTPUT

by Tom Jennings Revised 27 July 1999 Input/output, I/O, is the klunky and crude write-off phrase for the only part of symbolic machinery that's of any use or interest, where the alien innards tie to the world, mainly people. The interface between people and their machines is pretty much the limiting factor in making symbolic machinery useful. It's historically been a bottleneck and a weak point,...

Burroughs Corp. Nixie and Panaplex application notes

While there's sufficient information in the net and elsewhere to light up Nixies and make them work (see my Nixie datasheets) but as far as subtleties go (off-cathode leakage, ionization time vs. multiplexing, the reason for the funny digit stacking order) there's little out there. But here are a few useful Burroughs Application Notes. If you are trying to work with Nixies read N101 and N102, as ...

the Charactron

1. THE HARDWARE The Charactron (sometimes branded a Typotron), a special-purpose electron tube, was a peculiar device with a brief life, but appears to have been an important fulcrum of sorts in the history of computer graphics and art. This Note rather rambles; there's simply too much untold story in here, so I've settled on nailing down some facts and connections. In the 1950's, before Moor...

COMPUTING MACHINERY AND INTELLIGENCE

I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to es...

U.S.TTY/ITA2 to ASCII translation programs

The original contents of this page have been superceded by the history of character codes page. It now only contains the ITA :: ASCII conversion programs, updated and corrected in August, 1999. NOTE: though commonly called "Baudot", the 5-level teleprinter code is really called ITA2; there is also a variant informally called "U.S. TTY" that has a few differences in the FIGS case; see the above ...

The Sharp PC-5000

The Sharp PC5000 is a portable MS-DOS compatible machine. This means the hardware is not IBM-PC compatible, and it uses a special version of MS-DOS. 2.00 in this case. In the early days (1983) of the PC this was not uncommon. The screen is 640 x 80, giving it 80 characters wide by 8 lines. The PC-5000 has its design faults: DO NOT try to move the display backwards when it is in position. From a s...

Librascope/General Precision LGP-21 Computer

Tom Jennings, updated 16 September 2004 15 February 2003 This is the documentation for my Librascope/General Precision LGP-21 computer restoration project. The LGP-21 is the transistorized "little brother" version of the LGP-30 computer, a very popular vacuum-tube machine first produced in 1954. Though only a third the speed of the LGP-30, the LGP-21 was very small and consumed only 300 watts of...

Royal McBee/Librascope General Precision LGP-30 serial drum electron tube computer

--> These are just a few photos I took of the Computer Museum's LGP-30. You can find a few documents about it on the net with a Google search. I may or may not expand this page, depending on what I do with the LPG-21 I have. The photos are really crappy, sorry, it was too dark in there....

Mel the Programmer

Though this was written in the 1980's, the LGP-30 was a vacuum tube machine from the late 1950's. Steve Simmons writes: "Found, after a long time of fumbling around. Note the `source' line for email address and date. Yes, that's when it was posted. And that's what email addresses looked like back then."...

Data General NOVA4

Tom Jennings, updated 2 Nov 2006 Tom Jennings, updated 8 March 2005 (Bob R. is now the lucky owner of this machine now. I was never going to find the time to repair the disk logic.) This is my old but nice Data General Nova 4/X minicomputer. At the moment it contains the Nova 4 CPU, hardware floating point, a Model 6070 10 megabyte fixed/10 megabyte removable hard disk, Model 6023 800 bpi vacu...

Burroughs Nixie additional datasheets

Here are a few random datasheets that don't quite fit in the rest of the tube database scheme. These are courtesy David Forbes (www.cathodecorner.com) and will eventually be worked better into the indices (that's dictionary for more than one index).

Bits, Bauds, & Modulation rates

Serial communications, here meaning RS-232 and current loop 1999, revised slightly February 2005 mark and space -------------- Serial lines are either spacing, or marking. I was always confused as to what mark or space meant, which was the state of the line when no characters were being sent, etc. I can't understand why now, it's amazingly simple. The resting state is called "spacing". Mark...

BURROUGHS CORP. NIXIE FAMILY INDICATOR TUBES.

by Tom Jennings, tomj @ wps . com; last updated 31 Jan 1999 The capabilities of informational displays have historically lagged other information and computation technologies, just as they do today. Unlike current bit-mapped displays, relatively un-bound to the symbols they present, historically display devices have generally had a one-to-one symbol-to-mechanism mapping -- character(s) silk-scree...

They cannot be killed; you can still buy expendables from Western Numerical Control. Built into a hefty grey-wrinkle cabinet that sits on the floor, the fantastically complex, utterly reliable purely mechanical device spews out upp...

On holy wars and a plea for peace

This 1980 tale by Danny Cohen documents a now-forgotten (but ever-present) story about how data is transmitted serially over data links. There was once a war of sorts over it, but most of the combatants are long dead. While you don't often get tripped up by Little-Endian vs. Big Endian any more, the underlying issues of the representation of number within computers still matters, and for the curre...

Real Programmers Don't Use Pascal

[ A letter to the editor of Datamation, volume 29 number 7, July 1983. I've long ago lost my dog-eared photocopy, but I believe this was written (and is copyright) by Ed Post, Graphic Software Systems, Wilsonville OR USA. The story of Mel is a related article. ] Back in the good old days-- the "Golden Era" of computers-- it was easy to separate the men from the boys (sometimes called "Real Men" ...

Civil Defense Logo Dies at 67, and Some Mourn Its Passing

The Civil Defense symbol, left, born in 1939 and familiar to generations of Americans, has been replaced by an emergency management logo. The stark insignia of civil defense - a C and D forming a red circle in a white triangle on a blue disk - died yesterday after a long eclipse. It was 67 years old and lived in the mind's eye of anyone who remembers air-raid drills, fallout shelters and metal ...

First Draft of a Report on the EDVAC

Below is a copy of John von Neumann's EDVAC Report, in 150dpi image form. For some reason I was unable to find a copy of this famous paper anywhere on the net, which is both a shame and a shock, considering it's importance. This copy was taken from a book owned by the Computer History Museum, who kindly let me photocopy it. OCR sounds reasonable enough, but all I have are photocopies, and the pape...

Semiconductor datasheets and catalogs

I am just beginning to scan and index my solid state component catalogs and datasheets, as I have done for most of my electron tube data. It's a little ahrder to index in that the "catalogs" are often folded sheets with one or few devices per page; additionally, there isn't a consistent numbering scheme across all manufacturers, and manufacturers themselves changed the names of processes and logic...

Electron tube database, 1958--1961

Updated 5 December, 2003 This database contains technical specifications on some 2000+ electron tubes, mainly obscure and hard-to-find devices, mainly American JEDEC numbers. The technical data is contained in the high-resolution color scans of over 20 original catalogs from 1958 to 1963, and nested HTML indices of all the devices in the catalogs. Note that devices considered "receiving tubes", ...

Fido and FidoNet

This is a work in progress, and is unstructured and not illustrated. I'd been using BBSs since 1976 or so, 300 baud accoustic coupler type, rotary-dialing Chicago busy signals, but in 1984 I wrote my own, called Fido, and shortly thereafter a thing called FidoNet, a store-and-foreward emailing and file-transmission system that was (1) the first such thing, ever; (2) the largest privately-owned co...

Classic Computer Scams: World Power Systems, Inc.

--> In 1979 an outfit calling itself "World Power Systems, Inc." appeared on the scene with an amazing assortment of microcomputer peripherals, mostly for TRS-80 and S-100 systems. Alas, they were scam artists, taking people's money and sending nothing in return. A hint of this is visible in a photograph of their 3S+P Interface Card, shown in one of their advertisments. Although it appears ...
