Hey... That just tickled a long forgotten memory... Didn't Major Havoc use
two different crystals depending on if it was a kit or dedicated? (12MHz
vs. 10MHz?) Or am I totally making that up? ;-)

5% of 12,096,000 =604,800. So if the 12.096 MHz crystal was in spec at +/-
5% it could be less than 12MHz. Unless you are going for the world record
on the board the 12MHz crystals will be fine. I've used both for years with
no problems. I've even accidently used a 10Mhz crystal - the game worked
but the sounds were slower which gave it away.
