not sure..but just in case  when i did so back in the day when i ran the 
lost gonzo bbs on applenet bbs dos software (penchenck? author) and tpro 
4.2f rpg bbs and
fv/metal 4.0xev back in the distant past

anyway

i ran a twgs modified to 14mhz by doing the cuts on the bow ties mentioned 
and it ran that stuff 24/7 for 10 yrs with the CDA stating it ran cool 
enough at 13.75mhz was the sweet spot not too flaky not too hot....

so back in the day YOU DID  cut the ties

BUT I'M NOT SURE NOW

the REASON i'm mentioning all this is if you find YOU DO have to cut said 
ties DON'T cut them with the X-ACTO KNIFE COLD

ie i did not know that supposedly it worked best with a heated up xacto 
knife to cut thru the plastic and the traces i did it cold and it took me 3 
TRIES ...i damn near had a heart attack on the first 2 tries the xacto knife 
skip'd merrily accross the back of the board as it skip'd .. i would feel my 
heart stop in my chest.....i'd re-test after 1st try all was well...psych 
myself up for like an hour cursing to get courage for 2nd try....IT REPEATS 
ABOVE AGAIN...i again hyperventilate for another  hour after testing all was 
still well and 3rd time took...

most annoying and scary apple ii mod i ever did

so again those who know more then me i think i am correct you have to be 
VERY VERY CAREFUL and again i THINK the recomended method is to heat the 
xacto knife before hand and have a very steady hand indeed i gather the 
heating of the exacto knife is to get thru that first layer of plastic over 
the bow ties without said skipping problem.....(shudders)

hopefully you don't have to cut those ties anymore with the new hopefully 
better methods to do so on these mods i'm not up to date

good luck

anyway my 2c worth

(mumbles to self wanders away prob gonna have that nightmare again)
