why don't emulators such as the DM41X and V41 display the synthetic geese?

If my assumption is correct, I thinbk this answers the original question ...

Thomas, You are Correct!!!

I just did a quick and dirty patch for A=A-1, when A[MS] = F and in decimal arithmatic to force A[MS]=8.

Now I can see the goose (left and right).

More tests...
It seems the arithmetic mode doesn't really matter.

Patching A=A-1 (1BE) as:
if A[MS] = 0xF then A[MS] = 0x8
and it still works.


BTW: '1.234567891 E13' is displayed as '1"#$%&'()!'
