Since 2021, I've volunteered as a mainframe operator at InfoAge Science and History Museums in Wall, New Jersey -- a former U.S. Army base (Camp Evans) where the first radar bounce off the moon was achieved in 1946. I maintain and demonstrate a UNIVAC 1219B, a 1962 military computer built by the Remington Rand division of Sperry Rand.

The 1219B was a naval fire-control computer originally installed aboard U.S. Navy warships. Its job was to compute real-time targeting solutions for the ship's guided missile systems -- the Terrier, Talos, and Tartar surface-to-air missiles. The machine weighs over half a ton, uses 30-bit words, magnetic core memory, and was designed to survive the shock and vibration of a ship at battle stations.

I give tours and live demonstrations to the public on weekends, walking visitors through the front panel, the card reader, and the core memory -- showing people what computing looked like before most of their parents were born. I also participate in Vintage Computer Festival East (VCF East), the annual gathering of computing history enthusiasts at InfoAge, where I demo the UNIVAC for hundreds of visitors each year.
