This is an EXTERNAL version of the FujiNet 1.5. It is for ALL Atari 8-bit computers (Atari 400/800/1200XL/600XL/800XL/130XE/100XEL/1088XLD/576NUC+)
You will need an SIO cable to connect it to your 80-bit. It is NOT an end of chain device, you can put it anywhere in your SIO chain.
I still have to design the XE and 800 series cases. That may be awhile, so let me know if you want one to hurry me along.
