I highly recommend watching this YouTube channel[1]. It's the ultimate IBM 1401 simulator running on the Unreal engine. The level of detail is mind blowing. [1

  If I had the money, I would buy a VR headset for this developer in a heartbeat. It would be fascinating to see what that would add the experience. Especially if he added all of the sounds, to get that full HVAC experience...

  Here is the machine in action: https://www.youtube.com/watch?v=GZtLMMuLUuY https://www.youtube.com/watch?v=GZtLMMuLUuY Downloading the simulator is mandatory, since we're saving over $10 per minute in today's money compared with renting the original hardware. Also, the signs say “THANKS” instead of “THINK!” which is a nice touch :)

    Wow. 16,000 characters of memory (max), 11.5 microseconds cycle time, so 0.087 MHz = 87 kHz frequency. Wikipedia says $25k/month rental in today's dollars, which I calculate as being $34/hour. I could buy that much computer today with the loose change under my car seats.

      Indeed. The supercomputer in my pocket does high-resolution domain coloring and fractal generation in seconds or even just a fraction thereof, while the 1401 could probably have heated a house for a winter with the same compute load.
