A $15 rs422 to usb adapter and dj sures internet adapter software

The NABU computer is a great deal. You can buy one directly from [http://www.pellmill.com/](Pell Mill) and with efforts made by DJ Sures and others at https://nabu.ca there is a thriving infrastructure and community around it. Its z80 based and capable of running CP/M. From there you can run the MSX emulator and play many MSX games.
