Programming tools for emulator of eight bit computer ORAO
...It literally emulates every peace of hardware installed in real computer.

Unfortunately programming on emulator is also not so easy as it was on real computer, considering today modern tools. There are some external tools that enables writing program code in external text processor, and converting it to document acceptable by emulator.
DKU is an embedded parallel language, or "piggy-back" language that uses function calls to invoke the language's execution model. It tunes task-size to the hardware while hiding hardware details for high performance portability of parallel code.
Extensible language for portable parallelism. Any visual element may be used to extend program syntax and a re-writing rule defined for it. Syntactic elements have properties attached, enabling symbolic manipulation to specialize to hardware.
