FT-990 Menu Functions

[rsolomon@cctds.textron.com]

     I believe there are several menu functions available (such as
     determining CPU version) on the FT-990, but the instruction manual
     is a little light on the subject. Can anyone tell me what they are
     or point me in the right direction to get the info ?
