Like any good plan, you should always start with the intention to build a time machine. That way if your future self succeeds, your current self doesn’t have to worry about actually doing it!
Well, unfortunately it hasn’t quite worked out for hosts of [Toymaker], but they have managed to make a pretty authentic Telecom Time Machine instead!
What they’ve created is something called a “dumb terminal”. Back in the days of yore before personal computers existed, if you wanted to get “online” you would have to do so at a dumb terminal. It’s essentially a monochrome monitor, a keyboard, and a serial port. You would have to actually connect to the mainframe to do anything — but back then, you couldn’t just hook up a modem — oh no, you had to use an acoustic coupler to connect. You had to play sounds through your telephone in order to communicate with the mainframe. How’s that for a bit of history with your morning coffee!?
