Super cool. And thanks for links to the original manuals for those that want to take a deep dive. Feature request: I was wanting for a bit more sound… I mean,

Super cool. And thanks for links to the original manuals for those that want to take a deep dive. Feature request: I was wanting for a bit more sound… I mean, when I see "relay computer", I'm heading there for lots of soft clicks.

More…?! :) I totally feel you - the one reservation is that I’m using (gasp) not the original Minivac Relay sound. I need to go to a Computer Museum that will let me record one to offer a more authentic simulated experience. So tldr - let me get a clean real sound and then we can come back to this question :)

  I heard some clicks. I thought they were just the sounds of the switches I was toggling. Are there other (relay) sounds I somehow missed?

    Just to make sure I'm not misunderstanding: The relay click sound you're hearing should only happen when a relay turns on, and when it turns off. There is no sound when a button is pressed - you can check this by loading an empty simulator and pressing any of the buttons at the bottom (the simulator won't make any sound): https://minivac.greg.technology/simulator/ https://minivac.greg.technology/simulator/ ((Once/if I get to see a Minivac in real life, I may learn that buttons do make sounds..)) When a relay turns on and off, a sound is played. In the following circuit, check this by pressing and releasing the button 1: https://minivac.greg.technology/simulator/#wires=1%2B%2F1C%201F%2F1X%201Y%2F1- https://minivac.greg.technology/simulator/#wires=1%2B%2F1C%2...

  You may not need to get a museum's cooperation. After a quick search it seems these come up for sale from time to time. I saw one on the Vintage Computer Federation forums offered in 2021 for $500. You may be able to find a collector online who has one and will record the relays for you. A lot of folks have pretty high-quality USB mics for conferencing/podcasting these days. An alternative might be going to a regional VCF show where one will be (possibly by pre-arrangement with a collector). There are five or six shows held around the country every year. Unlike a museum almost all the devices there are available for hands-on interaction.
