I had absolutely never heard of this. Super cool! I unfortunately don’t own any of the supported platforms but this is awesome regardless.

No problem! You don’t need to own the hardware. You can use the pre-built fujinet-pc if your platform is supported, or just run Altirra (works fine from WINE if you’re not on Windows) and install the fujinet SIO adapter.

It’s pretty cool stuff getting on the internet with an emulated atari running an emulated fujinet IMO :)
