Any free (downloadable) Amiga turbo board PCB or circuit diagramm?

Since the "big" hardware manufacturer no more build any of the classic turbo card (68030/040/060), is there any pcb or circuit diagramm for free?

The Dave Haynie Archive has circuit diagrams and PAL code for most of the commodore CPU cards, like the A2630 and A3640.
Aminet have a few 14Mhz 68000 and 68010 mods.
Ermm, I think thats it.
back in the day there was a couple of magazines did A500 68030 designs for readers to build but none thats available on the net.

Back in December '88 Amiga Transactor published the LUCAS 020/881 board design for the A1000. I seem to remember a memory board for the LUCAS was published later.

Thanks, I find that. Sadly this design had its own limitations. Anyway it will be a good starting point for me.

the lucas board is very interesting but noisy electrically. add that to the electrial noise of the 1000 and you get instability many times. a loooooong time ago i tried cleaning up the design. it stated turning into my own accelerator design. then my a1000 died. not long after that i got a 1200
ive though of getting a 500 to goof around with since then, but now i have the 3000
