This old computer is comprised of four big boxes, three of which are ever actually used.

The UNIVAC 1219. This is the brains of the system. It controls the operations of every other device. This is what I'm referring to when I'm not gesturing to the UNIVAC 1219 as a whole.

The UNIVAC 1540. This is the DDR, or Digital Data Recorder. It holds, writes, and reads the magnetic tape operators load into the machine.

The Digital to Analog Converter. The UNIVAC 1219 was the first digital computer on most U.S. Navy ships, most of which had analog weapons systems. This hulking mass of steel translated the digital signals from the computer to the analog signals of the weapon systems and vice versa in regards to the radar.

The UNIVAC 1532. The I/O console managed the...you guessed it, input and output of the UNIVAC 1219. You can load and punch paper tape for programs more bite-sized than would be used for magnetic tape.

In addition, we have two teletype machines. You can think of them like typewriters that don't receive human input (except the one that can if we want), but instead output what the computer tells it to.  We have a Teletype Corporation teletype that is optimized for character compatability and a Kleinschmidt teletype that is optimized for speed. Both rely on the I/O console to send and receive data.

The real ingenuity begins with the floppy drive. Duane, who's career revolved around this system, developed a way for a floppy drive to imitate the I/O console. The computer thinks it is reading and writing to a paper tape, when it is in fact reading and writing to a 5.25in floppy inside an ancient CNC machine floppy drive.

And this, dear reader, is where the magic happens. This framework was originally built for interfacing with the 1219 via BIN files over Serial port and was easily changed to support BIN files over floppy. Duane has been working on an off adapting our purple converter box with a raspi to let the 1219 read and write BIN files over Bluetooth.

Make no mistake, you cannot simply SSH into this machine as tons of setup and channel changes must be performed to ready it to receive and send data. That being said, I don't see any other UNIVAC mainframes with Bluetooth [or any other running UNIVAC 1219s at all :(], so I will take what I can get.

Oh my goodness, my first question! Well, in a sentence, the UNIVAC 1219 was used to point and fire missiles at enemy aircraft. Now, we can break this down:

The UNIVAC 1219 is a militarized version of the UNIVAC 418. This thing has better resistance to salty air and other things you’d want a seafaring computer going into battle to have, but at their hearts they’re the same. There were three different missile systems the UNIVAC was a part of: Talos, Terrier, and Tartar. These three systems were among the first sea-to-air missile systems fielded by the U.S. Navy.

The UNIVAC 1219 would receive data from the AN/SPG-55 radar and analyze the data it received. Running one of dozens of programs lost to time (or on a single last-of-its-kind magnetic tape we are worried about damaging), it will pass on the results of its calculations to the missile system itself. The missile will go where it is told, and hit an enemy plane.

But our UNIVAC 1219 is unique! The specific machines here are from the John Hopkins Applied Physics Laboratory. At John Hopkins, they developed the fire control programs ran on Navy ships! They had a radar and everything, and I only wish we had a radar and missile battery too ;D.

As for what we do for demonstrations, we have assortments of cool programs we run, and I encourage you to swing by and see for yourself. Our oldest party trick is printing ASCII art of Spock and George Washington, but maybe if this post performs well I will divulge some other cool things we do ;).

How AI Can Modernize Legacy Systems

Classic ASP still powers critical business applications across industries - and abandoning them isn't always the smartest move. Sometimes the smartest move is finding someone who actually knows how to work with them.

The right Classic ASP developer doesn't just keep the lights on - they optimize, patch vulnerabilities, integrate with modern APIs, and extend the life of your system so you get more value before any migration is even necessary.

That's real ROI. That's not settling - that's strategy.

AI ROI at Risk? Is Your Legacy Tech Stack Blocking AI Success?

Many organizations are investing in AI, but few realize that outdated systems and fragmented architectures can quietly undermine results. Is your legacy tech stack helping AI deliver value or preventing it from reaching its full potential?

Despite the rise of modern frontend frameworks and evolving web technologies, AngularJS continues to survive in many enterprise environments. While officially considered a legacy framework, countless organizations still rely on AngularJS-powered systems for mission-critical applications and long-established digital platforms.

In 2026, companies continue using AngularJS for:

• Enterprise dashboard and internal business systems • Legacy web applications with large user bases • Long-term corporate software infrastructures • Stable workflow management platforms • Cost-sensitive modernization strategies

One of the biggest reasons AngularJS remains relevant is the enormous investment organizations made in large-scale applications over the past decade. Rebuilding entire enterprise systems from scratch often requires significant time, budget, and operational risk.

AngularJS also introduced concepts that shaped modern frontend development, including two-way data binding, dependency injection, and modular architecture — features that were revolutionary during its peak adoption years.

For many businesses, maintaining stable and functional legacy systems is often more practical than immediate migration, especially when existing applications continue meeting operational requirements effectively.

However, organizations still face growing challenges including security maintenance, developer availability, scalability limitations, and integration with modern cloud-native ecosystems.

The story of AngularJS in 2026 is not just about outdated technology — it is about the reality of enterprise software lifecycles, technical debt, and the complexity of digital transformation.

Sometimes the hardest systems to replace are the ones that still work.
