Not much of an update but @coonsgm is fiddling with the latest board in the background. I have not had time and probably won't do until the New Year to build up my new board.

However I did need to make measurements and had a hour to spare tonight amazingly! So I connected the 5.62 board up, which I know was working fine on my H5 some time ago.. But on the H4, amid some possible iffy connections, they basically would not reset and just had a white screen with a single green pixel line across the top. EMUTOS just said "EMUTOS 1.4" and nothing after. But that was basically a experimental build that I reversed on the next version and also made some other minor changes some months ago that I have completely forgotten about what I did and why.

So anyway, the more recent firmware (V4C2G) is running on the H4 now. I ran it though Claude and basically said the only thing it found was /AS was falling just before the rise of the clock, which, According to Claude, is wrong and should be after the rise. So That's been tweaked.. maybe someone off-hand knows which its supposed to be ? Too tired to go puzzling over datasheets tonight !

EDIT:

Quick measure of CLK8 and /AS and /AS falls on the rise of the clock. (stock H4)

Finally got my first build up and running (still trying to find likely a Xilinx soldering issue on the 2nd).

@coonsgm looks like you have no TTram?

Does TOS display the TTram check on a cold boot?

Also V4C2G is the current firmware.
