That was what naturally came to my mind too as all of the scads of HP stuff I have here and use daily is a lot older and 040's were just that, the HP-IB, now GPIB port board. I sent him an email suggesting it might just be the Universal option for the I/O of the system as with my 5328A's they are the only thing that the 040 is something other than the com port. Just food for thought and I hope I have not made things worse for him or am confusing anything. Now I am curious too as the data is not readily had on the net and you posted from a 19 series, his was a 5335A wasn't it???
