The [PC8080](/modules/pc8080/) machine below is configured to simulate a [VT100 Terminal](/devices/pc8080/machine/vt100/)
with a Control Panel and Debugger. It is running the original [VT100 Firmware](/devices/pc8080/rom/vt100/) inside the
[PC8080](/modules/pc8080/) CPU emulator.
[PC8080](/modules/pc8080/) CPU emulator. You'll also find assorted [Hardware Notes](#vt100-memory-usage) below.
Click the "Run" button to start the simulation. You'll also find assorted
[Hardware Notes](#vt100-memory-usage) below.
Click the "Run" button to start the simulation. 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
- F5: KEYPAD COMMA
- F6: BREAK
- F7: LINE FEED
- F8: NO SCROLL
- F9: SET-UP
The simulation is not fully operational yet, but it is now possible to access the SET-UP screen.

/*
* One of the many chips in the VT100 is an 8224, which operates at 24.8832MHz. That frequency is divided by 9
* to yield a 361.69ns clock period for the 8080 CPU, which means the CPU is running at 2.76Mhz (cycles per second).
* Hence the CPU component in the VT100's machine.xml is defined as:
* to yield a 361.69ns clock period for the 8080 CPU, which means (in theory) that the CPU is running at 2.76Mhz.
*
* Hence the CPU component in the VT100's machine.xml SHOULD be defined as:
*
* <cpu id="cpu8080" model="8080" cycles="2764800"/>
*
* where 2764800 = 24883200 / 9. You need to know this because we rely on the CPU frequency for simulating some
* of the other VT100 circuits.
* where 2764800 = 24883200 / 9. Unfortunately, the VT100 ROM decrements a countdown value in memory to determine
* cursor blink rate, and if we use 2764800 cycles per second, the cursor blinks MUCH too fast. It's surprising that
* the VT100 doesn't rely on vertical retrace interrupts for blink rate. Perhaps the designers were concerned about
* consistency across 60Hz and 50Hz display modes, although that seems like a minor concern, considering that the
* alternative means the ROM is now tied to a specific CPU operating frequency. However, short of rewriting portions
* of the ROM, we have to deal with it.
*
* And we deal with it by lowering cycles per second to 1000000 (1Mhz). I'm guessing that in a real VT100, the 8080
* gets bogged down by other factors (eg, the Video Processor's DMA requests), but we don't simulate the hardware to
* that level of detail, so the easiest solution is to lower the effective clock speed.
*
* NOTE: If you've noticed that the VT100 cursor blinks unevenly, you're right, and it's by design: the ROM uses a
* countdown value for the cursor's "on" state that is twice as large as that for the cursor's "off" state, so it's
* "on" twice as long as it's "off".
*
* WARNING: The choice of clock speed has an effect on other simulated VT100 circuits; see the DC011 Timing Chip
* discussion below, along with the getVT100LBA() function.
*
* For reference, here is a list of all the VT100 I/O ports, from /devices/pc8080/machine/vt100/debugger/README.md,
