Is it possible to convert a 6574A power supply to a 6674A? My understanding is that the only difference between the 2 is the GPIB capability on the 6674A. Is it simply a matter of installing a GPIB board into the 6574A and then running the initialization program in the service manual?
There is a Retrofit kit to add GPIB to 655XA & 657XA as shown below.
There is also a video use the link described below.
