Re: TF534 Not run

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

Can you do a manual memory test? $4000000 - $403fffff if I remember correctly? @PhilC I cannot do a manual test, I only have the 8A1 board, the GOTEK and the mouse connected. But it does the test https://archive.org/details/Advanced_Amiga_Analyzer_v2.00_1995-03-30_Wilcom it's okay so far IMG_202008...

Re: TF534 Not run

Re: CURRENT STOCK STATUS

I'll get some new MEGA DULATOS PCBs made. Though I'm not doing a full kit for them again.

Because there is a chance to buy and install such an extension...

@rubber_jonnie

it was a photo of my conversion adapter.

But you are right, it turns out that I will have a few adapters from local sellers guaranteeing their operation in TL866 and none of them will work !!

tl866 can't see 27c4096

Has anyone managed to program the epprom 27c4096 with the TL866 programmer?

I have a PLCC44 to 40 adapter in which I made changes with user suggestions in this forum.
But TL866 still can't see epproms?

What else do you need to do?
