Here it is, the Anomalies [BUGS] and the affected ROM levels

Anomaly                                                               Level
-------                                                               -----
The DEFINE command rounds numerical values in a user-defined            A
function definition according to the current display mode,
potentially losing accuracry in the stored definition.

Entry of a symbolic complex number in polar form '(A,<B)'             A,B,C,D
returns 'B*COS(A)-i*B*SIN(A)' instead of 'A*COS(B)+i*A*SIN(B)'

The NXEQ operation executed from the Graphics environment with          A
the Numerical Results flag (-3) set, may cause the current
equation to be overwritten with a numerical value.

The KGET command will cause calculator memory to be cleared if          A
you attempt to transfer a file of length 0 (zero) from your
computer.

If the Clock Format flag (-41) is set, so that the time is              A
displayed in 24-hour format, the Alarm Catalog will show the
incorrect ones-digit for minutes in the alram time.

The INV command returns an incorrect result if you attempt to          A,B,C
invert an 8 by 8 or larger matrix.

And, there they are...the sheet includes workaround and avoidance
procedures...but they're pretty stupid [like don't do it! kind of avoidance
steps].
