It's not operational yet, but as you can see below, pieces are starting to fall into place, including a test screen that
displays most of the VT100 font variations, built on-the-fly from the original VT100 Character Generator ROM, and LEDs that

as it processes the VT100's Non-Volatile RAM (NVR), and then it spins, awaiting further stimulus.
The VT100 KEYMAP table in [keyboard.js](/modules/pc8080/lib/keyboard.js) maps modern keys to VT100 key addresses,
and most of the mappings are 1-1. Function keys are mapped as follows:
- F1: PF1
- F2: PF2
- F3: PF3
- F4: PF4
- F6: BREAK
- F7: LINE FEED
- F8: NO SCROLL
- F9: SET-UP
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.
