I haven't looked through your SIMH procedure carefully, so there may be 
errors in it, but:

 - Unit 6 is the line printer.  I didn't see an "attach" for the LPS or LPT
   device, so you probably won't get any output.  Unit 1 is the console,
   so try "WRITE(1,99)".  (The mapping of units to SIMH devices is a
   function of which drivers are loaded in "sio16k11.abs".  The above
   mappings are typical.)

 - "R" format specifiers are not supported in HP FORTRAN (II).  FORTRAN IV
   does support "R".  Try "FORMAT(4HCIAO)" instead.

 - The correct manual for HP FORTRAN is 02116-9015, available from
   hpmuseum.net.  Later manuals describe FORTRAN IV and Fortran 77, which
   will have features that will not apply to the software.

That's it.

If you still have trouble after trying the above, let us know.
