Yes, GPIB/IEEE-488 is/was a big standard for control of instruments in
for example electronic engineering. Any professional instrument up
until a few years ago had such interface (default or as an option).

Search for GPIB, HPIB or IEEE-488 on ebay.

But maybe the timing problems André Fachat refers to might break this?

I definitively remember connecting the PET IEEE bus to 16 inputs on a
PC in the late 90's and writing a DOS program that logged all bus
states and being able to capture what was going on and seeing that it
seemed to comply to what I knew of the IEEE 488 standard back then.
