It's available the first release of this emulator for x86 systems!.
It is still in beta and has a lot to do. It runs once downloaded typing rpix86 or rpix86 -? for detailed information. To exit, simply press ESC or CTRL-C
For now only runs on console, so exit the desktop environment and start reminiscing abandonware classic.
