Unfortunately, one instrument computer is running DOS and I've never found a way to get USB working. I do have one of the adapters and it works seamlessly for newer implementations. If it works for DOS, it is beyond my skill level. By the way, this instrument is still world class in terms of accuracy and precision. To replace it would be 6 figures, not to mention having to deal with modern software, which is so much worse. I did think I could potentially use the USB to GPIB and interact directly over serial. There's one paper from the early 90s that describes the existence of a programming manual for the instrument, and gives a couple BASIC examples for how to do a certain type of analysis. But the actual programming manual itself seems lost to time. So for now, we are just limping along from vintage PC to vintage PC. We finally got one that uses ATX power supplies, so it should be easier to maintain.
