Only TOS 1.X works btw. I see you have a dual TOS ROM with 2.06 and 1.04. Is the jumper set for right TOS?

Tried with both TOS positions... I got a feeling one of my custom Atari chips got damaged in removal from the old board. Unfortunately I don't have any spares at all. I might need to ask one of you kind gentlemen to have a play with my board? Everything is socketed so swapping chips is no chore.

Bit of progress today with @Steve's H5.
It now consistently boots to a garbage screen.
(Ignore the yellow its my monitor lead playing up)
I think once I connect the serial up on this then I'll get it diagnosed and up and running

If you carry on at this rate @PhilC your reputation for fixing things will surpass your one for breaking things

So the Serial port arrived the other day and is now fitted to the H5 but now I'm even more confused 
I worked out that part of the problem was with the MFP and swapping that for another new one has made the H5 more consistent.
When I boot the H5 with Diagrom it gets to the main menu but looks like a bit is stuck somewhere on the serial , so I get mostly garbage on that.
When I try and boot with tos1.04 and a diagcart installed I get this via serial:
ˇ....Q. Leklqvg Bmk Ejjwj pavdtqvg..Vw 0Q.1 ejjwj....
On the screen I get:
testing MFP, glue Timing, Video
E9 Bad instruction fetch.
I think I either have a bad data line or something similar.
