The glory of vintage computer were all the blinkenlights!

The AN/FSQ-7 on TV and in the Movies
The USAF AN/FSQ-7 (SAGE) computer systems were the largest computers ever built, and were responsible for keeping a radar eye on our air space for more than 25 years until decommissioned in 1983. The Q7 was also a special effects dream, with more lights, switches and vacuum tubes than any other piece of hardware, and found its way into many science fiction movies and television programs over the years.
The IBM 7030 Stretch was a close second.
