DEC VT100 Terminal
This is an updated PCjs emulation of the 8080-based DEC VT100 Terminal.
Unlike other VT100 emulators, our VT100 is emulating the original VT100 hardware, running the VT100 Firmware inside the PCx80 CPU emulator.
This VT100 can connect to other PCjs emulations, like this IBM PC AT or even itself, as well as physical (remote) systems, like the vintage computer systems at SDF.ORG.
