Each year Compuseum celebrates in solidarity with Philly Tech Week.
Philly Tech Week presented by Comcast is an annual love fest with "all things tech" in Philly.
Bringing together the #PhillyTech community for a week of events showcasing the city’s vibrant ecosystem.
Welcome to Compuseum's Philly Tech Week Event
This event is organized by Compuseum
This is a Virtual Event with a pre-recorded presentation of annual World Computer Day topics. It is free; courtesy of Sponsor generosity.
5PM-7PM (eastern USA) on Zoom platform on Wednesday, the middle of Tech Week.
Two Hour Virtual Presentation. 10 VIP speakers, 15 minutes each.
Join in for short period or for entire event. Talk with folks you know or meet new friends!
Feel free to bring libation of choice!
Did you know that Philly is the "Foundry of Modern Computing?" Join us for this exciting event, including a deep dive into the technologies that launched the "Computer Age" right here in the Delaware Valley. This event provides a unique opportunity to engage with the speakers in a Q&A following the presentation by experts in the field. Chat with the masons of the computer generation who laid down the original building blocks in the birthplace of electronic computing.

The Selectron was an early form of digital computer memory. Constructed in Lancaster, Pennsylvania and developed by the Radio Corporation of America (RCA). It was a vacuum tube that stored digital data as electrostatic charges using technology similar to the Williams tube storage device. A stepping stone in memory devices that then led to the magnetic-core memory which became almost universal.

Philco was one of the pioneers of transistorized computers. After the company developed the surface barrier transistor in Lansdale, Pennsylvania, which was much faster than previous point-contact types, it was awarded contracts for military and government computers. Commercialized derivatives of some of these designs became successful business and scientific computers. The TRANSAC (Transistor Automatic Computer) Model S-1000 was released as a scientific computer. The TRANSAC S-2000 mainframe computer system, marketed as the "fastest computer in the world, was first produced in 1958, and a family of compatible machines, with increasing performance, was released over the next several years.

The ILLIAC (Illinois Automatic Computer) was a series of supercomputers built at a variety of locations, some at the University of Illinois at Urbana-Champaign. In all, five computers were built in this series between 1951 and 1974. The most inspirational was the Illiac IV constructed in Paoli, Pennsylvania having one of the first attempts at a massively parallel computer. Key to the design as conceived by Daniel Slotnick, the director of the project, was fairly high parallelism with up to 256 processors, used to allow the machine to work on large data sets in what would later be known as array processing.

The System Source Computer Museum displays technology from the inception of computing. Founders Bob Roswell and Maury Weinstein opened ComputerLand, a predecessor to System Source, in 1981. Rapid advances in technology in the early 1980’s made some ComputerLand inventory obsolete before it could be sold. Bob and Maury’s old ComputerLand store on Redwood Street had a bank vault in the basement, so they filled it with vintage technology. Today, the extensive collection is at the headquarters of System Source, an IT systems integrator in Hunt Valley, Maryland. Bob enjoys leading tour groups, building the museum’s collection and sharing stories of vintage computers with Museum visitors.
