Finally, I verified that reassembling [VT100.asm](VT100.asm) with [asm8080](https://github.com/begoon/asm8080) produced the
original VT100.bin; after adding the correct number of `nop` instructions to the end to the source file, the binaries matched.
The other advantage of reassembling the code is that the resulting [VT100.lst](VT100.lst) makes it easy to export comments
The other advantage of reassembling the code is that the resulting [VT100.txt](VT100.txt) makes it easy to export comments
and other symbolic information to [VT100.map](VT100.map), which can then be included in the [VT100.json](VT100.json) ROM dump
and passed on to the PC8080 Debugger. Here are the rebuild steps:
asm8080 -lVT100.lst VT100.asm
grep -E "[0-9]+ [0-9A-D]+.*;;" VT100.lst | sed -E "s/ *[0-9]+ ([0-9A-F]+).*;(;.*)/ \1 . \2/" > VT100.map
asm8080 -lVT100.txt VT100.asm
grep -E "[0-9]+ [0-9A-D]+.*;;" VT100.txt | sed -E "s/ *[0-9]+ ([0-9A-F]+).*;(;.*)/ \1 . \2/" > VT100.map
filedump --file=VT100.bin --format=bytes --output=VT100.json --comments --overwrite
You can omit `--comments` from the filedump command to reduce the size of the [VT100.json](VT100.json) file.

Front Panel Basics
------------------
From the [PDP-11/70 Handbook (1979)](http://archive.pcjs.org/pubs/dec/pdp11/1170/PDP1170_Handbook_1979.pdf), Chapter 10, p. 325:
> ### CONSOLE OPERATION
> The PDP-11/70 console allows direct control of the computer system. It contains a power switch for the CPU,
which is also usually used as the Master Switch for the system. The console is used for starting, stopping, resetting,
and debugging. Lights and switches provide the facilities for monitoring operation, system control, and maintenance.
Debugging and detailed tracing of operations can be accomplished by having the computer execute single instructions or
single cycles. Contents of all locations can be examined, and data can be entered manually from the console switches.
The PDPjs Front Panel replicates most (but not all) the features of a real PDP-11/70 Front Panel. The switches, which
PDPjs displays as green to make them stand out from the rest of the pink-and-magenta controls, are summarized below.
### 0-21
These control bits 0 to 21 of the SWITCH register. The UP position represents a ONE, and the DOWN position
represents a ZERO. Once all the bits have been set, you can choose to load the contents of the SWITCH register into the
ADDRESS register (as displayed by the top row of LEDs), or directly into the memory location referenced by the ADDRESS
register (where it will become the DATA displayed by the second row of LEDs).
The SWITCH, ADDRESS, and DATA (aka DISPLAY) registers are all internal to the Front Panel hardware, and should not be
confused with CPU registers.
### TEST
This is a momentary switch that is normally in the DOWN position. When held in the UP position, it turns on all LEDs.
This "lamp test" was more important in the days when the lights were produced by bulbs with filaments that could burn out,
and if you didn't realize that a particular light was "burned out", you could mistake it for a zero.
While the TEST switch is more "cute" than useful on a virtual Front Panel, we have added one "innovation" to the switch:
pressing it also returns all the SWITCH register switches (0-21) to their DOWN position.
### LOAD
This is a momentary switch that is normally in the UP position. When pressed DOWN, it copies the SWITCH register to the
ADDRESS register.
### EXAM
This is a momentary switch that is normally in the UP position. When pressed DOWN, it reads the memory location referenced
by the ADDRESS register and displays it in the DATA register. If pressed repeatedly, each repetition also automatically
adds 2 to the ADDRESS register, making it easier to examine a series of words. Note that if the CPU registers are being
examined (starting at address 177700), the ADDRESS register will advance by 1 instead of 2.
Another "innovation" unique to PDPjs: if the STEP switch is toggled from the UP to the DOWN position, repeated EXAM operations
will decrease the ADDRESS register instead of increasing it.
### DEP
This is a momentary switch that is normally in the DOWN position. When pressed UP, it writes the contents of the SWITCH
register to the memory location referenced by the ADDRESS register, and displays the result in the DATA register. Like the
EXAM switch, if DEP is pressed repeatedly, each repetition also automatically adds 2 to the ADDRESS register, making it easier
to deposit the same value to a series of words.
### CONT
This is a momentary switch that is normally in the UP position. When pressed DOWN, it will start the CPU if it's currently
halted. If the CPU is already running, CONT has no effect. Also, if the ENABLE/HALT switch is in the DOWN (HALT) position,
then the CPU will continue for only ONE instruction and then stop again.
### ENABLE/HALT
This switch is a toggle that is normally in the UP (ENABLE) position. If it pressed DOWN while the CPU is running, the CPU will
stop. Once the CPU is stopped, this switch has no effect, other than determining what CONT will do when pressed.
### STEP
On a real PDP-11, this would select between cycle-stepping vs. instruction-stepping. Since PDPjs doesn't support cycle-stepping,
this switch has no effect (except as described above when the EXAM or DEP switches are pressed repeatedly).
### START
The START switch is similar to CONT, but it also performs the equivalent a RESET instruction before starting the CPU, so
unless you're starting execution at the beginning of a program, using START instead of CONT to continue execution is probably
not a good idea. Also, if the ENABLE/HALT switch is in the DOWN (HALT) position, START will still reset the machine but not
execute anything.

Other interesting things to know about this machine:
* It includes an [M9312 ROM](/devices/pdp11/rom/M9312/) at address 165000. The exact ROM is [23-616F1](/devices/pdp11/rom/M9312/23-616F1.txt).
Toggle-Ins
----------
As DEC notes in the [PDP-11/70 Maintenance Service Guide](http://archive.pcjs.org/pubs/dec/pdp11/1170/PDP1170_Maintenance_Service_Guide_Apr88.pdf),
Chapter 4: "There are several useful toggle-ins that are probably not very well known." Excerpts are provided below.
Chapter 4: "There are several useful toggle-ins that are probably not very well known." Excerpts are provided below. If you're
not sure how "toggle in" code using a Front Panel, check out [Front Panel Basics](/devices/pdp11/machine/1170/panel/#front-panel-basics).
However, since the above machine also includes the PDPjs Debugger, you'll find that it's much easier to use the Debugger commands
described below to load and execute these "toggle-ins".

PDP-11 M9312 ROM Images
-----------------------
An assortment of M9312 ROM images, source listings, etc, are available from Don North's [website](http://www.ak6dn.com/PDP-11/M9312/),
some of which we have reproduced here.
Initially, all we had was this [256-word ROM](M9312.json) obtained from Paul Nankervis' [website](http://skn.noip.me/pdp11/iopage.js).
Cross-referencing that ROM with Don North's [M9312 PROM Files](http://www.ak6dn.com/PDP-11/M9312/) revealed that it came from
DEC P/N [23-616F1](23-616F1.txt): "11/60,70 Diagnostic/Console", albeit with some unexpected changes:
165322 022716 165320 L26: cmp #N2,(sp) ; 165320 changed to 000320
...
165332 012716 165342 L27: mov #N3,(sp) ; 165342 changed to 000342
...
165344 012746 165354 mov #N4,-(sp) ; 165354 changed to 000354
...
165354 000137 165362 N4: jmp @#N5 ; 165362 changed to 000362
165360 000000 halt ; 000000 changed to 000200
...
165372 012737 165400 000004 mov #N6,@#4 ; 165400 changed to 000400
...
165406 012737 165714 000114 mov #N12,@#114 ; 165714 changed to 000714
The unmodified [23-616F1](23-616F1.json) ROM can be seen at address 165000 when configured in a
[PDP-11/70](/devices/pdp11/machine/1170/panel/debugger/) like so:
<rom id="m9312" addr="0xEA00" size="0x200" file="/devices/pdp11/rom/M9312/23-616F1.json"/>
As this [PDP-11 website](http://www.pdp-11.nl/pdp11-34a/cpu/options/bootstrap-info.html) explains:
> The M9312 Bootstrap/terminator module contains a complete set of UNIBUS termination resistors and 512 words of ROM that can
be used for diagnostic routines, the console emulation routine and bootstrap programs. The module has 12 jumpers, W1 thu W12,
and five sockets to put ROMs in. One socket is used for a diagnostic ROM for the PDP-11/60 or PDP-11/70, or for a ROM that
contains the console emulation routine and diagnostics for all other PDP-11s. The other four sockets accept ROMs that contain
bootstrap programs.
