Hi Roger,
actually I have an USB based GPIB adapter, but without controlling Software to read/write I won't be able to do much. The only I GPIB SW I use with this is Pete Millet's package for the HP 8903 distortion analyzer. Embarking on a big DIY effort to figure out the commands etc.. not really in my skill set. That's why I was looking for "spare parts" approach of swapping chips.
Thanks
Paba
