I would like to use a TF520 on a Atari ST with TOS 2.06 ...

For what are the Jumper?

- JP1 (Clocksel) ?
- JP2
- JP3 CPU Cache enable/disable
- JP7

JP1

Mainboard CPU Clock over Buffer chip - Clock In - 32Mhz Quarzoszillator

Setup= MST4 -> Lightning ST -> Magnum ST with 8MB -> TF520 with 32Mhz Onboard TF520 Oszillator

looks interesteing I have Atari 520 STfm and I'm waiting my Lightning board & Cloudy board. So I can use it with this. Anything to say how to set it up?

Is it possible to close case?

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?
