Alright here they are:

*1: Menu no  pause no
*2: Menu yes pause yes
*3: Menu yes pause no

0607688 I-0692  *1
0608737 I-0692  *1
0736033 I-0792  *1
0858919 I-0892  *1
XXXXXXX I-0892  *1  (wasn't given entire SN)
1019705 I-1092  *2  (this is my calculator)
0614771 I-0693C *3
0622644 I-0693C *3
0726585 I-0793C *3

There appears to be a sort of pattern here.
Notice that all of the SNs that end with C are of type *3.
Someone has suggested that the numbers after the I- is a date
(ie I-0892 = August 1992)  I'm guessing that this is the date of
manufacture.  The C may represent a ROM revision.  This is all speculation
so don't blame me if I'm wrong.

It does seem weird though that the first set of calculators(by date) are
the ones that weren't suceptible to either "trick" and therefore seem to
be superior.

I just realized something very peculiar, mine is the only one that follows
the conditions of type 2.  I wonder why.
