With the Lightning ST you can use TOS 2.06 but you have to build adapter for the two 32pin eproms in the 28pin rom sockets. The TF520 need TOS 2.06 or EmuTOS or you can use 6 pieces of 27C256 Eproms with KAOS TOS on it.

I'm getting Cloudy board from Team Thunderstorm with EmuTos.

Installing TF520 to Atari with Lighning is plug n' play?
