wouldn't have any data on what, exactly, the voltages and timing for the
 1702A would be, would you?  
 If he doesn't, then I have the Intel 1702A data sheets and schematics for 
 their programmer, as used in the MCS8I (I think that's for the 1702A, not 
 the 1702, but I would have to check). I also have schematics, etc for at 
 least one DIY 1702A programmer (the PE CHAMP-PROG, FWIW).

 Be warned these are not friendly chips to program. Several of the pins 
 have to be raised to 40V-ish voltage levels.... 
  A -47V programming pulse comes to mind, in particular...
