TI-92 bug (revisited)

I just picked up my TI-92 today, (un?)fortunately it is only a ROM 1.7.
However, I was able to get 'undefined' for some removable singularities.
I'm curious whether the bug was introduced in later versions... In 1.7,
everything is as it should be...


Define y1(x)=(x^2-6x+5)/(x-5)                    Done


y1(x)                                             x+1


y1(5)                                           undef


limit(y1(x),x,5)                                    4


ZoomDec               [graph of y1(x), hole at (5,4)]


Table: tblStart 2
       delta    .5

3.    2.
3.5   2.5
4.    3.
4.5   3.5
5.    undef


Now, if there is anyone with a ROM version other than 1.7 (especially later
ROMs) PLEASE reply via personal email, or to the list.  I want to be able to
see removable singularities, and if this problem exists in later versions,
I'd like to know before I exchange mine.  Also, reply via personal email if
there are any known bugs in 1.7...


TIA,
