@fcab100 I believe that you are mixing tables. X variable was defined in the nex table, so DSY9 enable (200, 100, Men, Dec and Trig).
The table to which I refer is only for Y. If I'm not mistaken Y variable directly affects only to the new features.
Cheers.

Code table: Use DSYX for a official key, and use VSYX for a trial key.
X 200, 100, Mem, Dec, Trig
A none
B == == == == on
C == == == on ==
D == == == on on
E == == on == ==
F == == on == on
G == == on on ==
H == == on on on
Note: keys A..H wont change the model, only ADD an option.
2102:
J == on == == ==
K == on == == on
L == on == on ==
M == on == on on
N == on on == ==
P == on on == on
Q == on on on ==
R == on on on on <- All 2102

T on == == == on
U on == == on ==
V on == == on on
W on == on == ==
X on == on == on
Y on == on on ==
Z on == on on on <- All 2202
DONT USE BELOW Not recommended, as activates 2102 and also 2202:
2 on on == == ==
3 on on == == on
4 on on == on ==
5 on on == on on
6 on on on == ==
7 on on on == on
