Hi,
would you check the difference between your mobo and this photo :

It seems that you have just 2 straps around W2 and W4 that enable the presence of the ROMs.
If you disable these straps, do you get back to the good old KICKSTART hand's screen ?

Try to dump the 2 roms, it's the only way to know if it's splitted by :
1st method : 16 bits word splitted in 2x 8bits word (1st in EVEN, 2nd in ODD... or may be the inverse !)
2nd method : simply divided in the 2 roms.
Keep the Faith !

I hope you'll get success in your research, i'm not sure that would get better than kick 1.3. And I also think that you'll need to dump the 2 others roms.

I wonder about the 2 jumpers, if they are "open" may it turn back to a "standard" A1000 ?
Keep the Faith !
