It makes all the beeps and chirps you’d expect from the real hardware, and there’s even some OpenGL trickery used to mimic an old CRT display, complete with scan lines and a soft glow around characters. The idea here is that an an 8080 emulator actually runs an original VT100 firmware ROM, warts and all.

So he went ahead and started developing a custom terminal simulator for it to run. He loved the look of the printed VT100, and thought it deserved better than a generic terminal emulator. The addition of an RS-232 Serial HAT to the Raspberry Pi meant that the 3D printed VT100 could actually operate as a serial terminal using software such as minicom. But as any hacker knows, some projects end up developing a life of their own. A peek into the case revealed nothing more exotic than a Raspberry Pi running its default operating system, making the terminal just as well suited to emulating classic games as it was dialing into a remote system. When finished his scaled down DEC VT100 replica a few months ago, he made it very clear that the project was only meant to look like a vintage terminal on the outside.
