My only suggestion is to try the other 2 firmware as they run the CPU at 8mhz and see if IDE behaves then..

Trying a different CF card now...if that doesn't work I'll try the other firmware

Might also be an idea to show how you fitted the patch board.. it's odd as @Steve and @Badwolf seem to be stable now but not you :shrug: by the sounds of it, the changes didn't help at all ? So can only assume you have a different issue :shrug:

So BW is stable now? What did he do?

Same as you..

Here's a photo of the patch board.

Ah I suppose that means removing the cap and osc. Because last I knew he'd installed the board, but was unstable.

Seems fine...

It was unstable, then he removed the cap and was fine...

My concern is , why is the timing so sensitive to start with... If I go back to the original TF536 timings, TTram doesn't work at all... Even on the ST536..

My only idea at this point would be to move to a 288xl PLD as I can only think some timings off due to the compiler struggling to fit the code in a 144.

@Steve Which cap did you remove? I assume the oscillator is the one closest to the patch board.
