Hello everybody,
not sure if somebody already didnt post that, but I found another source for TF530 FPGA processor socket. This should be good alternative to:
https://www.ebay.com/itm/250474705812

One I already ordered is here:
http://www.buyicnow.com/it.php?i=297

Hope that it can be useful..

Can anyone confirm if "State Of The Art" demo runs with KS 3.1 on an accelerated Amiga 500 (TF530 preferably) with a GoTek? My system read 2 tracks and then bombs out.

I just have the HD converted exe on my Amikit installation - no problems to run on 030 emu and KS 3.9.

Yeah emulation isnt what he's asking about here. Specifically a real 030 accelerator and a gotek.

Did you check if it works without accelerator? There are 2 different variants of SOTA, one requires 1M chip and other that works with 0.5M+0.5M. 1M chip version without 1M chip will hang/crash in few seconds after booting.

Ooooo. I didn't know that. I actually was using my 68SEC000 accelerator (but I didn't want to diverge too much from thread topic) and my OCS patient 0 Amiga 500 only has 512K ChipRAM. I was actually thinking I have an issue with some strange DMA cycle or exploit fixed in the 68SEC000 which was being taken advantage of. I will check that out!

good evening dear Amigans and Retrofans!
Have some news i wanna share here. Some of You heard on Stephen's streams that he plans to send some TF534 prototype boards to beta testers.
He kept his word - have thankfully received one of his TF534 boards. Of course i was so excited that i started to build it same day - luckily i had almost all parts here already..Of course i have choosed different RAM type (Cypress instread of Alliance) as mentioned in the BOM, have done it as a proof of concept, as i am a beta tester - will give my two pennies also and test different parts to find out incompatibilities and possible bugs.
Today i got Amiga firmware, flashed the card....and it just works! What a good feeling!!!
My card is running @24Mhz currently, and it does very well and stable. Havent noticed any crashes, glitches or freezes. Seems this successor of our beloved TF530 is well designed, runs really smooth and stable.
Next steps will be try a higher frequency and of course i will move to my favourite Amiga - A2000 and test this card throughly on it. Cheers,

Viktor

PS
Thank You very much Stephen, i owe you a lot of beer now.. Have You ever planned to visit Munich and Oktoberfest?

You will need the DMA fixes from the Atari ST before that will work well. I will sort it soon.

Not a hope. I am a father who spends his weekends learning to write again in his (once) native language. Its seriously cutting in my playtime

Victor. If you have a scope it may be worth getting a trace of the CPUCLK line and comparing it with a TF530.. Hopefully much cleaner

That's good idea, will compare!
Have tried 40 & 32Mhz oscillators, 40 reports RAM as defective, 32Mhz starts to boot, but hangs, so swapped back to 24Mhz atm
it's Cypress RAM after all, so i am happy it works at all

I had issues with ram until i used multilayer caps on the board. I used X7Rs under the ram chips. You added all the caps?

Yes, all caps are present, are MLCC's. Not sure X7R or X5R's...
i am happy card works nice and stable, that's a good start point. Will add ROM/SPI IC later

I guess the alliance ram was actually much better spec than advertised.

What is the speed of that cypress stuff?
