It's real easy. When going from hex to decimal, convert the prefix first, the 
prefix is the first two digits. For Mitsubishi it's 86 which converts to 134 
in decimal. Then take the remaining 6 digits and convert them to decimal, put 
the prefix on the front and the remaining 8 decimal digits on the back and 
you're all set.
To go from Decimal to hex, convert the first three digits to hex, then the 
remaining 8 digits to hex.
There are cases where an esn will come out with one less digit, when that 
happens you need to put in a zero after the prefix so that the esn converts 
from 8 to 11 digits or 11 back to 8.
Should be fairly easy to program up in quick basic.
