Finished building the 1st one this afternoon. I've spent the last few hours testing with a rev 6A A500 - all working fine! No issues whatsoever! Fast booting, although it reports around 800KB/s in benchmarks, I am not using an MMU with this board atm.
Great job Stephen! Really pleased with it =D Will test on my A2000 boards shortly!
I also then tested with the A590 fitted and it works with that too! Bare in mind the A590 is forced into a slower IO mode (like 100KB/second) - nothing to do with the 536! That same issue happens with the A4000, due to it not being able to DMA into the ZIII RAM. But the fact it works with the A590 is great stuff - had 64MB ZIII, 2MB ZII, and 1MB Chip RAM.
EDIT: PS - if you want to leave this doing a RAM test, go book a holiday and come back in a few days time

The bad news (I could be using the wrong firmware?) - I cannot get it to boot on my 3 x A2000 boards.
All behave the same way (I have 2 x rev 6 boards, and one rev 4 board). Factory fixes applied to the rev 4 and one of the 6 boards - so a good mix to test against.
Most of the time I just get a black screen, but I noticed something interesting - if I remove the CF card shows the rainbow coloured bands from the initial boot every time! Stick the CF card back in and the coloured lines seldom ever show - just a black screen.
And here's a short "private" clip of the behaviour - it did still show the coloured bands at the end of the video there after re-inserting the CF card, but 99% of the time the bands dont show if any of my CF cards are plugged in there. No rush on any kind of fix - just posting this to help Stephen, tbh I bought these for my A500's and they work fine in my rev 6A (I will test rev 5 and rev 3 later just out of curiosity more than anything), so I am happy =D If at some point it works in the A2000 too that's a bonus for me!
And to be sure the CF card and the A2000's are OK, I swapped back to the TF534 and they all boot without issue with the 534. Swapped a number of times between the 534 and 536 to make sure its not the CPU slot or the adapter too.
EDIT: Video is unlisted btw - please don't share anywhere. Just here to show behaviour. Will be deleted later!

How big block size did You used, Gadget?
I am not sure off the top of my head! I can check - where's the best place to see that (HDToolBox maybe?).
I can boot with various different CF cards though, some formatted myself, others from previous TF cards etc. They all work perfectly on the A500 for me. Just the A2000's at the moment I have issues with, but that might be me putting the wrong firmware on it or something.
