 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,
