The card works fine. It operates at a frequency of 33-50 MHz without FPU.
Failed to boot from FPU: x yellow screen
Now for permanent mounting on the ATARI 520ST.
What (* .jed) CPLD batch for ATARI?

Re: TF534 Not run
Don't run it at 50. The alliance 55ns ram can't cope with it. You should not go above 40.

Re: TF534 Not run
If you want ram to run reliably at 50MHz, use: CY62158ELL-45ZSX

@terriblefire @alenppc
i changed the oscillator to 33mhz. FPU has started and runs stably. Tests done with Amiga 500. THX
@8 Bit Dreams
I have uploaded the files from @agranlund
Atari starts up. But Ultrasatan doesn't work with TOS 2.06. Atari hangs when starting reading the SD card.
