There’s some interesting artwork on the timeshare computer…reminds me of the “nose art” on military aircraft. In my archival research I’ve come across a few instances of pinup-style material, especially ASCII art printouts.

The video below is from 1973, slightly after the timeframe of my research, but certainly interesting.

The Holmdel Computer Center, Part 1 – AT&T Archives (Wayback Machine link)

The year was 1973, and the computer operating system UNIX, invented at Bell Labs by Ken Thompson and Dennis Ritchie, had just morphed into its third iteration or improvement, and had just been rewritten in the C programming language. This film, made as an orientation for the computer center at the Bell Labs Holmdel location, is a rare glimpse into the operations and procedures of an early 1970s research-oriented computing center. And as the 1973 Holmdel Computer Center only had IBM computers, it wasn't running a UNIX installation: the system was only ported to IBM computers in the years to come. In 1973, UNIX as a system was limited to installations on DEC computers, and there were UNIX installations at other locations of Bell Laboratories such as Indian Hill, Whippany, and, of course, Murray Hill (where UNIX and C were developed). Computers in the Bell System weren't just relegated to computer science or the development of computer language. They were employed for all kinds of complex engineering calculations, telecommunications applications, and, very occasionally, for making art and music.

The original video isn’t available on the Wayback Machine, but the YouTube version is embedded below.

SITE BUILDING 002 - SCANNER BUILDING - LOOKING AT DISC STORAGE SYSTEMS A AND B

The year on the photo is listed as 1999, which seems too recent given the feel of the picture. In the high-resolution TIFF, however, the date can be seen on the bulletin board, “21 Oct 99”. The Cyber 170 was produced in the late 1970s, so this unit is at least 20 years old.

The photograph is part of this collection at LOC: Cape Cod Air Station, Technical Facility-Scanner Building & Power Plant, Massachusetts Military Reservation, Sandwich, Barnstable County, MA

Campus digital workhorse running final laps after 35 years (Wayback Machine link), by Barbara Palmer, Stanford Report, 2003:

The remarkable thing is not that the mainframe will be retired -- the 35-year-old system is "like a jet slowly losing its engines," said Dick Guertin, a software developer who has worked at Stanford since 1970. What is amazing, say those whose work lives have spanned much of the computer revolution, is that the mainframe system and the ground-breaking applications designed here to run on it have held up so well for so long.

At its peak, there were 30,000 accounts, including noncampus users, on the mainframe. Some of what McWilliam is doing requires real detective work, since many of the people who opened the accounts have long ago left Stanford or retired.

Also – Forsythe Mainframe Retirement (Wayback Machine link):

The mainframe era officially ended on December 15, 2003 when the last of the mainframe accounts was closed down.

Hello, Goodbye - CDS Bids Farewell to Mainframe, Ushers in New Beginning

In 1998 the Catalog Distribution Service of the Library of Congress shutoff its mainframe computer and switched to a new system.

During the 1970s, the mainframes were used primarily to print catalog cards, which CDS once produced by the tens of millions. In those early days, as many as 30 staff members were required simply to service the units, performing such tasks as changing tape reels, threading tape and programming. "It was physically demanding labor," said Mr. Billingsley.

In 1947 a moth was found in a relay switch on the Mark II electromechanical computer, a true computer "bug." What's most interesting here isn't that an insect was found in the machine, but that the computer operator taped the moth into the logbook. It's almost as if the moth was trapped in a thin sheet of amber, preserved as the pre-digital ancestor of the tricksters within our own modern devices. 

The insect was found by Grace Hopper (Wayback Machine link), a computer scientist and rear admiral in the US Navy. Google recently paid homage to Hopper with a "doodle" (below) showing her working on an early mainframe computer. Not only does the computer display an answer on a paper printout, but a moth also flies out at the end of the sequence.
