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?

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

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.
Card without FPU
