Note that, unlike most emulators, PC8080 (like PCx86) has a *[Bus](/modules/pc8080/lib/bus.js)* architecture,
allowing components to "plug in" different kinds of memory or memory-mapped devices at different addresses,
and to register specific functions for specific I/O ports.
For example, Space Invaders has 8Kb of ROM at addresses 0x0000 through 0x1FFF, which means that if any 8080 code
attempts to write to those addresses, nothing should happen. Unfortunately, most emulators treat the entire address
space as one contiguous array of bytes. Which means either that the ROM is susceptible to corruption *or* that every
write operation must check the address to determine its validity, which hurts the performance of *all* writes.
In PC8080 (and PCx86), all writes are equally fast, and all ROMs are fully protected. An exception is made for the
Debugger, which allows you to use the "e" command to modify ("patch") ROM code on the fly, but that is completely
outside and independent of the 8080 code being emulated.

Unlike other VT100 emulators, it is not simply an emulation of VT100 protocols. It is a simulation of the original VT100
machine, running the [VT100 Firmware](/devices/pc8080/rom/vt100/) inside the [PC8080](/modules/pc8080/) CPU emulator.
Admittedly, terminals aren't that useful in isolation, since they're designed to be connected to other (host) machines.
But once this PCjs VT100 Terminal simulation is fully operational, you can expect to see it used in conjunction with a variety
of other PCjs machines.
For now, play with the [Debugger Configuration](/devices/pc8080/machine/vt100/debugger/), which also provides information
about VT100 internals and links to other technical resources.

VT100 Memory Usage
------------------
As described in the [Technical Manual (July 1982)](http://bitsavers.informatik.uni-stuttgart.de/pdf/dec/terminal/vt100/EK-VT100-TM-003_VT100_Technical_Manual_Jul82.pdf),
p. 4-15, 8Kb (0x2000) of ROM is located at 0x0000, and 3Kb (0x0C00) of RAM immediately follows it at 0x2000. The ROM at
0x0000 contains all the VT100's 8080 code. The VT100 also contains a 2Kb character generator ROM, but that ROM is not
addressable by the CPU; it is used directly by the Video Processor.
See [DEC VT100 ROMs](/devices/pc8080/rom/vt100/) for more information about the ROMs.
[vt100romhax](http://vt100romhax.tumblr.com/post/90697428973/the-vt100-memory-map-and-8080-disassembly)
(aka [phooky](https://github.com/phooky) aka Adam Mayer) further explains VT100 memory usage:
Start End Size Description
0x0000 0x1fff 8K Basic ROM
0x2000 0x2012 18B Blank lines for refresh (6 x 3B)
0x2012 0x204f 61B Stack area (grows down from 0x204e)
0x204f 0x22d0 641B Scratch Pad/Setup Area(?)
0x22d0 0x2c00 2352B Screen RAM
VT100 I/O Ports
---------------
From p. 4-17 of the Technical Manual:
READ OR WRITE
00H PUSART data bus
01H PUSART command port
WRITE ONLY (Decoded with I/O WR L)
02H Baud rate generator
42H Brightness D/A latch
62H NVR latch
82H Keyboard UART data input
A2H Video processor DC012
C2H Video processor DC011
E2H Graphics port
READ ONLY (Decoded with I/O RD L)
22H Modem buffer
42H Flags buffer
82H Keyboard UART data output
The PC8080 ChipSet component deals with the ER1400's Non-volatile RAM (NVR) ports, the Flags buffer, and the
DC011 and DC012 circuits, while the Keyboard component deals with the Keyboard UART.
You might wonder why the PC8080 Video component doesn't manage the DC011 and DC012. In fact, the above labels are misleading.
If you look at the Functional Diagram on p. 4-53 of the Technical Manual, you'll see that DC011 and DC012 are really
peripheral components providing inputs to the Video Processor. Moreover, they are not exclusive to the Video Processor.
For example, the LBA7 output of the DC011 is also used to clock the NVR chip.
In most respects, the VT100 Technical Manual provides a phenomenal amount of detail.
However, documentation for some of the above ports is almost non-existent. It's only thanks to
[third parties](https://github.com/phooky/VT100-Hax/blob/master/Platform%20Notes.md) that we have, for example, the following
information about the Flags buffer (port 0x42):
Bit Active? Description
7 H KBD Transmit Buffer Empty
6 H LBA 7(?) (It's a pin on the backplane connector...) - used to clock NVR - line buffer address
5 H NVR DATA
4 L EVEN FIELD (comes out of the video timing generator)
3 H OPTION PRESENT (terminal output option???)
2 L GRAPHICS FLAG (is VT52 graphics card present) [I think he meant VT125 -JP]
1 L ADVANCED VIDEO (is AVO present)
0 H XMIT FLAG
VT100 Video Processor
---------------------
Normally, the PC8080 Video component allocates its own video buffer, based on the specified buffer address
(*bufferAddr*) and other dimensions (eg, *bufferCols* and *bufferRows*), but the VT100 is a little unusual:
it has a custom Video Processor that uses DMA to request character data from any region of RAM, one line at a time.
It always defaults to address 0x2000 for the first line of character data, but each line terminates with 3 bytes
containing the attributes and address of the next line, so the location of subsequent lines will vary, depending
on the type of line:
- Single-wide characters (80 or 132 columns)
- Double-wide characters (40 or 66 columns)
In addition to single-wide vs. double-wide, line attributes can also specify double-high, along with whether the
top or bottom halves of the double-high characters should be displayed, because double-high always implies double-wide
(ie, there is no support for double-high, single-wide characters).
Conssequently, a VT100 [machine XML file](machine.xml) must set the Video component's *bufferRAM* property
to "true", indicating that existing RAM should be used, and a new property, *bufferFormat* must be set to "vt100",
enabling support for the VT100's line data format; eg:
<ram id="ram" addr="0x2000" size="0x0C00"/>
<video id="video" screenWidth="1600" screenHeight="960" bufferAddr="0x2000" bufferRAM="true" bufferFormat="vt100" bufferCols="80" bufferRows="24" ...>
VT100 Screen and Character Dimensions
-------------------------------------
Ordinarily, the VT100 screen displays 800 dots per horizontal scan, and a total of 240 horizontal scans, and by default,
it uses a 10x10 character cell, for a total of 80 columns and 24 rows of characters. However, in 132-column mode, it
uses a 9x10 character cell instead, implying a total of 1188 dots displayed per horizontal scan. This means we will have
to dynamically reallocate our internal buffers whenever the horizontal dimensions change. Also, if no AVO expansion
card is present, there is only enough RAM available for 14 rows of characters in 132-column mode.
For optimum scaling, I define the virtual screen size using multiples of the VT100's default "dot" dimensions; eg, 1600x960
(a horizontal multiplier of 2 and a vertical multiplier of 4). That gives us a virtual screen aspect ratio of 1.67.
According to the Technical Manual, a physical VT100 screen measures 12 inches diagonally, and in 80-column mode, characters
measure 2.0mm x 3.35mm (in 132-column mode, they measure 1.3mm x 3.35mm), which suggests that the text area of the screen is
roughly 160mm x 80mm, implying a screen aspect ratio of 2.0. However, after visually comparing the Technical Manual's SET-UP
screenshots to our test screens, 1.67 appears to be closer to reality than 2.0. I'll revisit this issue at a later date.
