Please also note that Equi doesn't specify any graphical or sound output capabilities. If such support is required, it generally must be implemented, as with any other peripheral, via the port I/O interface (`P`) instruction specific to a particular hardware/software implementation. Same goes for how standard serial terminal input/output is processed: Equi specification doesn't enforce any particular way. On the desktop/laptop PCs, however, it is advised, especially for software-based implementations/VMs, that the terminal I/O should be VT100-compatible, including, for instance, control character support and the output of an audiovisual bell for ASCII 0x07 (`\a` or `^G`). Depending on the target, these features may already be supported by the underlying OS's terminal emulator or may be implemented as a part of the VM itself.
See [FizzBuzz](examples/fizzbuzz.equi) for a more thorough example of how different features of the current Equi specification are used.
## Reference implementation
Being a purely PC-oriented low-level runtime/programming environment, Equi has the reference implementation emulator/VM written in C (ANSI C89 standard), `equi.c`, compilable and runnable on all the systems supporting standard I/O. Note that, for portability reasons, this emulator:
