I would need a
dump of the chips or at least A04A2 / E102 on the Control
board.
Can you clarify? Is this a typo?
No, it is not a typo. Why do you think it is typo?

Page 91. M7261. E102 / A04A2.
When comparing my chip, which I removed and dumped, it is very different
from the listing. Maybe half the chip differs. The
problems in the
microcode flow definetely matches the contents of the dump.
I am getting a little worried that there are different versions of the
microcode. Anyone knows of different versions?
