The 534 works fine in the ST. I am using one in my 520STM, flashed with @agranlund 's firmware as seen here:
https://github.com/agranlund/tf534/tree/master/bin

You will need either TOS2.06 (which will have to be decoded) or one of the 192K EMUTOS images flashed onto the 2(6?) ROM chips on your motherboard. The older versions of TOS will not boot with a 68030 processor.

More info on the 192K EMUTOS (and download below) :

There may be newer versions of this in the forum, but it is what I used with no issue in my 6 chip 520STM before building the decoder.

Hope this helps.

Yes thanks EzdineG, it was agranlund's thread I was following.

I'd say you're likely to get more 030 software expecting an FPU on the Atari side than the Amiga too, so the 534 does look like a good option for the ST all around.

I assume memory accesses are *phenomenally* fast on a 534 too, on account of the SRAM?

How did you end up flashing the chips on the TF534 board because I can't get mine to work right now?
