This could be a picture of me - I worked on 7094 Serial #3 at JPL. The core memory was oil-cooled. The repair guy changed the oil. | |||||||||||||
Model 7094 computer system c. 1965 Model 7094 Console The Model 7094 was an extension of the Model 7090, which was a transistorized version of the earlier Model 709 vacuum tube computer. Popular for scientific applications, IBMs customers included NASA, which used the machines for its Apollo space program. Shown here is the operators console. The entire system, including peripherals, occupied 2,000 square feet. It was highly successful, with almost 200 systems sold.

This could be a picture of me (surprise!). I have the magnetic tape from JPL with the Fortran program I wrote to drive the Stromberg Carlson SC4020 microfilm plotter. It took in data from a Mariner satellite and plotted the terminator (line between day and night) on Mars and the outline of Mars. The output was just a circle with a line through it. I still think it is the first computer generated graphic of a planet. If JPL asked me to just draw a circle with a line, then they had not done it. This was outsourcing - IBM Federal Systems was contract programming. The JPL guys told me the algorithms and I simply implemented them in Fortran. The round white thing is a CRT (CHARACTRON) that projected light on microfilm. The little box on the extreme left is the microfilm roll. The rest of the box is photographic developer hemicals - one hour photo! |

April 7, 1964 - I was in IBM class at the punchcard building on Lincoln north of the airport. The computer was the IBM 1401. I recollect it was the last day of class when someone said IBM had announced a new computer. | |||||||||||||
At JPL I also worked on the development of HASP
- Houston Automatic Spooler. You ran programs on the expensive 7094 and wrote the output
to a connected 1401 which printed the output - compute on the expensive machine and print
using the cheap machine.Early 1960's: IBM 1401 Data Processing System |

Model 1401 1959 IBM Corporation, United States First introduced by IBM in 1959, the Model 1401 Data Processing System was popular with small businesses for applications such as payroll, inventory, and billing. In larger computer centers, the computer was often used as a print spooler to offload print jobs from a larger, more expensive system. Users programmed this variable-word-length character machine using Autocoder (assembly language), RPG, COBOL, and other languages.

http://www.thegalleryofoldiron.com/705.HTM My first computer - my senior highschool year I drove down to OU campus, took a computer class on the 705 in the morning and went to the football game in the afternoon. Glory days! | ||

You guys saw this printer at Comm-Pro at Goat Hill. Phone lines connected it and a card-reader to USC. Comm-Pro could run jobs without driving to USC. State-of-the-art! Took a forklift to lift it to the 2nd floor Goathill office. | ||

I walked into Xerox thinking I knew everything and saw pictures on a computer screen instead of characters! I was blown away. Apple walked in and saw it and copied it. The Mac is a ripoff of the Alto. Xerox stockholders should arrest the Xerox president of the time for failing to market what Xerox created! | |

Ricercatori alla Xerox PARC decidono di sviluppare un computer da usare per le ricerche e progettano un PC sperimentale denominato Alto, che usa il mouse, rete Ethernet ed una interfaccia utente grafica (GUI). Xerox ALTO personal computer Di questa macchina non ne furono venduti molti esemplari, dato l'alto costo, ma rappresentò il trampolino per lo sviluppo di personal computer ad interfaccia grafica. il rivoluzionario schermo verticale e interfaccia grafica di Xerox Alto |
The IMP is the first Internet router. UCLA had an IMP and USC Engineering PDP/11 connected to it which in turn was connected to our 360/65 machine via an infrared transmitter I installed. I have the IMP manual in the garage. | |||||||||||||
Interface Message Processor Interface Message Processor The Interface Message Processor (IMP) was the first packet router for the ARPANET, the predecessor of todays Internet. Inside was a Honeywell 516 minicomputer with only 6,000 words of software to monitor network status and gather statistics. The first ARPANET transmission occurred between the University of California in Los Angeles and Stanford Research Institute in Menlo Park, California, at 22:30 PST on October 29, 1969.

When the Soviet Union launched the Sputnik satellite
in 1957, the US government responded with dramatically increased support of
technology research and development, much of it funded through the new Advanced Research
Projects Agency (ARPA). In 1966 Bob Taylor of ARPAs computer research division obtained funding for a network called ARPANET to link computers so that resources and results could be shared more easily. He hired Larry Roberts of MIT to manage the project, which was based on newly-invented packet-switching technology. At the end of 1969 the ARPANET began operating with four nodes: University of California at Los Angeles and Santa Barbara, Stanford Research Institute, and University of Utah. That original ARPANET gradually grew into the Internet, which 30 years later had about 43 million nodes. |
