The ‘Penn State Automatic Computer’ →

Some local history on one of the first large-scale university computers.

They secured $25,000 in University funds and $17,000 from the National Science Foundation for constructing PENNSTAC — Penn State Automatic Computer. The machine they envisioned would cost $300,000 on the commercial market. Yet building it from scratch, Tarpley said, would provide his team of faculty and graduate students invaluable hands-on experience.

And this:

According to a 1957 account in the Daily Collegian student newspaper, PENNSTAC could “perform 1,400 additions of 10-digit numbers in one second, and its magnetic drum can store 2.5 thousand 10-digit figures.”
