 Unlike other VT100 emulators, this isn't simply an emulation of VT100 protocols.  It's a simulation of the VT100's
 8080 CPU, running the original [VT100 Firmware](/devices/pc8080/rom/vt100/) inside the [PC8080](/modules/pc8080/)
 CPU emulator, along with other key components that the CPU interacts with to drive the display, keyboard, and serial port.

 The initial goal for the simulation is to provide a virtual terminal that can communicate with other PCjs machines
 and provide a realistic serial communication experience, all from the comfort of your web browser.
