There is an entire VM available for download, when run will provide an entire virtual Atari 8bit (via Altirra & wine) and AppleII (via AppleWin/Linux) that connects to the ‘virtual’ FujiNet (aka FujiNet-PC).
It’s a simple download of an ova file that can be opened by virtualBox (still free from Oracle) and run on your desktop.

Enjoy FujiNet powered Atari or AppleII today without buying a thing. Hopefully you like it enough to buy one for your real hardware and enjoy the power that FujiNet brings these platforms.
