70340A options

I would like to upgrade my 70340A, of course no longer supported, to the options:
1E8 1Hz frequency resolution. I guess, after reading the manual, it is a software related option ; is it tied with the serial number and does anybody in the factory  still get the unlock key ? It seems common with the 83731A.
1E1 step attenuator : I have got a 90db attenuator from a 83731A and the piece of cable coming with it is a still available part. But, how can I tell the microprocessor, there is an attenuator ? It was very easy with the 8340/1 and 8360X : you had to change by the front panel a documented cal constant in the CPU...
Thanks
