INT 66 - Newkey v5.4 - INSTALLATION VECTOR
Return: immediately (IRET)
Program: Newkey is a shareware keyboard macro program by Frank A. Bell
Note:   the installation check consists of testing for the signature bytes
          FDh FCh FFh FEh at offset 03h in the interrupt handlers segment;
          Newkey may use any interrupt from 60h through 67h and will install
          on the highest vector in this range which is unused (normally 66h)
BUG:    the code obviously intends to use INT F0-FE, INT 70-77, and INT 68-6F
          before falling back to INT 60-67, but only uses the last of these
          ranges in v5.4
