|

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.
|
||||
A [Debugger Configuration](/devices/pc8080/machine/vt100/debugger/) is also available.
|
||||
|
||||
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.

From the SET-UP screen, you can press **4** to switch to LOCAL mode and verify local operation of most VT100

keys. The following keys have special meaning inside SET-UP Mode.
